Frequently asked questions
What is needed to control the arm?
A microcontroller such as an Arduino, or a similar board, sends PWM signals to the four servos. SG90 servos are typically powered from about 4.8 to 6 V, so use a supply that can deliver enough current for all servos.
Are the servo motors included?
Yes, the kit includes four SG90 servo motors for the arm joints.
