Hi,
im new here and new with Arduino stuff so I need help.
I planned to build my one drone. I have an receiver and an transmitter and 4 brushless motors with ecs and i want the motors to move depending on a joystick value the transmitters transmitts.
My problem is, any of the motors move as they should after i calibrated the esc's. Sometimes they start moveing and when the joystick is in the (comeing from 0 going to full throttle) middleposition they stop and go in calibration mode again. Also i have to calibrate them new everytime i attach the battery. They all "beep" correctly in the calibration (100% then 0% throttle) but then just one or none moves for 5 sec or so then they start calibration again.
I guess i have some code problems why this doesnt work at least with one of the motors. It's the same with every motor. The transmitter is fine and gives the right values (from 0 - 180).
Also is it correct that i can only use certain Pins on my Arduino nano to control the ESC's?
I read that only certain Pins can create a PWM signal i need to control those so I cant just use PINs 2-5? Is there a way around that because the other Pins are in use for the radiotransmittion/receiving.
Hope someone can help me. Thanks.
