For a project we're building a robot arm, using three MG946R servos and one MG90S servo. Now I was wondering how to control those since I've been tasked with acquiring the hardware.
I think the MG90S takes a 3.3v PWM signal since I've worked with its 'brother', the SG90, before. Can we use a 3.3v PWM signal for the MG946R servos too? Seeing that they use 6V for power.
Also, what micro controller would you recommend? I assume it would need four pins with PWM to control the four servos
Thanks for any help!
