Hi! I’m planning to begin work on small quadruped robot soon, and I’m thinking of making an ultra cheap, ultra accessible one, using 12 mg90s 9g servos.
should I hook up the signal wires of these to my Arduino/esp32 directly (power source will be separate)
Connect the signal wires to a pwm motor driver, and connect that to the microcontroller?
I do not completely understand the purpose of the pwm motor driver, so if someone would be kind enough to explain that a little that’d be great too!
