Frequently asked questions
How do I wire the FS90MG servo?
It has three wires: signal, power (positive) and ground (negative). Connect the signal wire to a PWM-capable pin, and connect the ground to the controller's ground so both share a common reference.
Can I power the servo from the Arduino 5 V pin?
For a single small servo at light load, a board's 5 V pin may work, but servos draw current spikes under load. Check the servo's rated voltage and use a separate supply for multiple servos or heavy loads.
