Hello, I would like to show you how to control electric linear actuator with Arduino. This is a simple Arduino board with edge bridge which controls DC motor. Position of exit shaft of this DC motor is controlled by simple encoder. Position is realized by simple converter, USB to serial converter and an application made in Python to control positions of the actuator. Here you can save fixed position where the actuator can go if you activate any input digital input of your board. For example we will save this position and the other position. So this position are saved in the memory of microcontroller. Now we will try to send the actuator to position 150. This field shows that the actuator will move forward. Here we have position 150 reached so we have information that drive is in position. Go back to position 0. We have information that drive is in position. Now to position for example 356 I have marked previously. Go to 0. You can see that all the time actual position of your actuator is marked here. I have made some function of emergency stop just to stop at any time our actuator. So we have stopped at 536 normally you should use a limit switches to disconnect electrically motor if there are any software problems. You can see that the motor slows down 10 points before reaching a position. This is just to eliminate any oscillation. Anyone go back to zero
