Hello everyone As part of my school project, which has a modernizer a laser levelling (For building sites), I have to realize a program to control two DC motors using an Arduino UNO and the DRV8835 shield.
My objective is that the upgrade should be done automatically when the device is turned on according to the data of an accelerometer.
The system is composed of 2 DC motors, each of which drives a gear and worm system, allowing the laser beam
My problem is the following: I must be able to stop the motor of the installation and a contact with the machine and have it repaired in the other without, BUT without using sensors or other type of detectors. I have only a few 100nk100 capacitors and resistors but I do not know how to use them. Knowing that the current in the motor increases it is blocked, I like to think of using the overcurrent, but I do not see how to do it.
Thank you in advance for your conference and your potential answers, Yassine
