Hi all!
I made a small application(MIT2) to control 4 servomotors using a HC05 module with arduino, but when I command one the rest get a little pulse, how can fix it ? Thanks!

What power are you using, and how is it connected? To get real help we need to see your wiring diagram and the code… Help us we help you, we can’t see or imagine what your doing!!

Hope it helps.
