CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This patent application claims priority to U.S. Provisional Patent Application Ser. No. 62/280,553, filed Jan. 19, 2016, which is incorporated herein by reference in its entirety. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    The embodiments described herein relate to a seed planter and, more particularly, to a user interface for a control system for real-time monitoring and controlling seed depth placement during operation of the seed planter. 
         [0003]    Conventional planting implements currently used in no-till farming, commonly referred to as “planters” utilize a seed channel opener, typically in the form of a disc, that creates a channel or furrow in the soil for seed placement. No-till planting involves planting the seeds into untilled ground. Because the ground is untilled, the field has greater variances in soil conditions. In other words, the untilled field has non-uniform field conditions. In general, three types of soil conditions are observed. First, under moist soil conditions, the seed bed can become compacted by excessive down pressure. Second, under hard, dry and/or compacted soil conditions, insufficient down pressure can result in a seed channel of inadequate depth or a seed channel simply not formed, resulting in seed placement on the soil surface. Third, in soft soil conditions, the seed channel can be cut too deeply by excessive down pressure, resulting in seed placement which is too deep. 
         [0004]    Prior efforts at controlling seed depth rely on a specified down force load/pressure exerted on a planter row unit, or bank of units. An assumption of seed depth is made based on the specified load/pressure. However, as described above, the soil conditions vary and therefore the planted seed depth is varied under a specified load/pressure. 
         [0005]    Negative consequences may result from soil variance. Consider the farmer who initially sets the down pressure of the planting implement to accommodate the average soil conditions in his field. When hard soil conditions are encountered, the down pressure exerted on the seed opener is not sufficient to create the seed channel. Thus, the seed is placed on top of the ground, thereby lowering crop yields. When wet or soft soil conditions are encountered, the down pressure exerted on the seed opener is excessive. In wetter soil, this excessive pressure will cause compacting on either side of the seed channel and can cause accumulation and pushing of mud. In softer soil, this excessive pressure can cause the seed channel to be cut too deep. These conditions also lower the crop yields. Finally, the excessive down pressure in both wet soil and soft soil conditions is an unnecessary burden to both the tractor pulling the planter and the depth control wheel bearing of the planter. 
         [0006]    Despite prior attempts to develop a planting implement capable of providing a constant depth of soil penetration, a need still exists for a planting implement and control system for providing real time control of a depth control device which can accurately and precisely control the depth of a seed channel being cut. 
       SUMMARY OF THE INVENTION 
       [0007]    In accordance with one aspect of the invention, a seed planter adjustment system includes at least one component of a seed planter that is adjustable for controlling a seed planting depth. Also included is a controller in operative communication with the at least one component. Further included is a user interface in electronic communication with the controller, the user interface receiving an adjustment command from an operator to remotely adjust the at least one component. 
         [0008]    In accordance with another aspect of the invention, a seed planter adjustment system includes a seed planter.

         [0009]    These and other advantages and features will become more apparent from the following description taken in conjunction with the drawings. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0010]    The subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other features, and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which: 
           [0011]      FIG. 1  schematically illustrates an embodiment of a seed planter described herein. 
       
    
    
     DETAILED DESCRIPTION 
       [0012]    Referring now to the  FIG. 1 , where the invention will be described with reference to specific embodiments, without limiting same, an automated electronic precision planting system is shown. 
         [0013]    Rather than requiring manual adjustment of individual elements of a modular row design for a planter  10  (e.g., hydraulically), the planter control system, as described herein, provides an operator the advantages of an automated adjustment system. As shown, the planter  10  includes a plurality of row units  12  that each individually plant seeds or other agricultural products. Although six rows are illustrated, it is to be appreciated that more or less rows may be included. The depth of planting of the seeds and/or products impacts the farming yield and efficiency. Therefore, adjusting the planting depth based on the soil conditions is often necessary. This may be done by adjusting the downforce applied with each row unit, for example. 
         [0014]    The system described herein allows an operator to remotely adjust the row units  12 . In some embodiments, a signal is sent in a wired manner to one or more elements of the planter  10  to adjust the row units  12 . In other embodiments, a signal is sent wirelessly to one or more elements to adjust the row units  12 . Irrespective of whether the signal is sent in a wired or wireless manner, a user interface  30  that is in operative communication with the planter  10  allows a user to remotely adjust elements of the planter  10  to control planting depth of the row units  12 . In some embodiments the user interface  30  includes a controller integrated therein. In other embodiments, the controller is in operative communication with the user interface  30  and the row units  12  and is disposed at an intermediate location. 
         [0015]    In the embodiment shown, the user interface  30  is located onboard a tractor  20 . The user interface  30  may include a touch screen, buttons or other interactive components that allows the operator to input commands. In some embodiments, the user interface  30  is permanently fixed to the tractor  20 . In other embodiments, the user interface  30  is a mobile device, such as a tablet, laptop, phone, smart watch, etc., that an operator may interact with. It is contemplated that a non-permanently fixed device, such as a mobile device, may be physically connected to the tractor  20  to establish a wired electrical connection to the planter  10 . 
         [0016]    Regardless of the specific type of user interface employed, the operator may adjust each of the modular row design elements for each respective individual row unit at the same time and consistently. Each row unit will have the same loads exerted based on the similar signal being sent to each unit. In another embodiment, different rows may be adjusted differently than adjacent rows. The individual rows may have a distinct signal being sent to different rows to affect the respective rows. In this way, adjacent rows may be adjusted differently. 
         [0017]    Disclosed is an electronic communication between the planter  10  and the tractor  20 . In the case of wireless communication, the communication may be provided by any wireless technique available. In an embodiment, the wireless technique is a Bluetooth connection, schematically represented with element  22 , utilizing any one of an Android, Apple, or any other input device having a human interface, as described above, with Bluetooth enabled technology. Other components of a wireless system  40  include a wireless gateway to a controller area network (CAN) bus  24 , an automation master control  26 , and ground speed sensors  28  that include GPS  38  in some embodiments. The wireless gateway to a CAN  24  bus utilizes a bi-directional gateway between planter  10 , the user interface  30 . A CAN 2.0 B 500 k band network may be employed in some embodiments. 
         [0018]    The automation master control  26  is a stand-alone automation master that does not rely on user interaction after setup is complete in some embodiments. The ground speed sensors  28  include GPS  38 , wheel speed  32 , radar  34 , or combinations of each to determine ground speed. 
         [0019]    In one embodiment the modular row design, as illustrated in individual rows  1 - 6 , utilizes an automated down force actuator  50  having a brushless motor driving ball screw via a worm gear. A PID controller calculates position and provides error reduction via a control algorithm. In the illustrated embodiment, each individual row unit  12  also includes an electronic driven seed plate  60 . Seed plate  60  utilizes a brushless motor driving seed plate via a worm gear speed reducer. A PID controller position based velocity error reduction is provided via a control algorithm. Optic seed sensors are monitored directly by the controller of the seed plate  60 . The seed plate controller includes advanced features of seed plate preload, and skip/doubles calculations. In one embodiment it also includes distributed calculation power. 
         [0020]    In the embodiment shown, each individual row unit  12  of the planter  10  includes remote electronic seed depth control  70 . Remote electronic seed depth control includes a brushed motor driven by a FET H-bridge controller with encoder position feedback. Other features include Binary speed control, and Tertiary direction control algorithm. 
         [0021]    The above-described sensors and components detect a number of conditions that affect seed planting depth at given downforce actuator settings. The detected conditions are sent to the controller and/or user interface  30  and processed to determine if an adjustment is required. Detection may be performed continuously in a nearly instantaneous manner or may occur at spaced intervals. 
         [0022]    Advantageously, an operator may remotely adjust components of the planter  10  to control planting depth, thereby eliminating the need to manually do so. Additionally, each row may be controlled to account for soil characteristic variation to optimize planting depth of all seeds and/or agricultural products. 
         [0023]    While the invention has been described in detail in connection with only a limited number of embodiments, it should be readily understood that the invention is not limited to such disclosed embodiments. Rather, the invention can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the invention. Additionally, while various embodiments of the invention have been described, it is to be understood that aspects of the invention may include only some of the described embodiments. Accordingly, the invention is not to be seen as limited by the foregoing description.
