SainSmart Mobile Car Kit with Sensor Shield V5 + 4WD Mobile Platform + Dual H Bridge Stepper Motor Driver + HC-SR04 Ultrasonic Distance Sensor + UNO/UNO R3/Mega2560/Mega R3(optional) for Arduino (UNO, Silver)
Uno is a microcontroller board based on ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.UNO R3 is improved version. It uses an ATMega16U2. This allows for faster transfer rates and the ability to have the UNO show up as a keyboard, mouse, joystick, etc. No drivers needed for Linux or Mac.MEGA2560 is based on the ATmega2560. It has 54 digital input/output pins, 16 analog inputs, 4 UARTs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.MEGA2560 R3 uses an ATMega16U2 which allows for faster transfer rates and more memory. No drivers needed for Linux or Mac, and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. It also adds SDA and SCL pins next to the AREF.Sensor Shield V5 has the COM and I2C (IIC) ports separated, so that both ports can be utilized at the same time to increase the possibilities of use.4WD Drive Mobile Robot Platform can hold many controllers, drivers, sensors and RF modules etc. It supports plate with controller mounting holes, 2 dof pan. Tilt holds down groove, collision switch mounting hole, can be added with sensors.Ultrasonic Module HC-SR04 Distance Sensor: There are 4 pins out of the module : VCC , Trig, Echo, GND. So Distance = ((Duration of high level)*(Sonic :340m/s))/2Package Content1 x UNO/UNO R3/Mega2560/Mega2560 R31 x Sensor Shield V51 x 4WD Mobile Platform1 x Dual H Bridge Stepper Motor Driver1 x Distance Sensor* Brackets areNOTincluded.Note:Download documentation here:https://s3-ap-northeast-1.amazonaws.com/sain-amzn/20/20-011-C55/car-uno.rarhttps://s3-ap-northeast-1.amazonaws.com/sain-amzn/20/20-011-C56/car-mega.rar
