I have a heating problem that causes desynchronization after 3 minutes of running of my 8 servo motors RDS3135. One on 4 servos also stop. The pro-micro gets really hot and regulator and heat sink also.
My setup is ;
1- Arduino Mega plugged to 9v power supply
with HC-12 transmitter on a breadboard
2- 2 breadboard connected to 12v powersupply and alimenting each 4 other breadboards (so total 8 breadboards)
3- On each 8 breadboard controlling each a servo RDS3135
I have 1 promicro, 1 HC-12, 1 regulator L7805CV, heat sink on each regulator, 1 capacitor 100nf, Electrolytic Capacitor - 1uF/50V.
Any idea what I am missing? Or should do to solve this problem ?
