SunFounder GalaxyRVR Kit for Arduino, Release 1.0
Servo motors are special type of motors that don’t just spin around and around like a wheel. Instead, they can move
to a specific position and hold that position. Imagine if you’re playing a game of Simon says, and Simon says, “Raise
your arm to a 90-degree angle!” You can do it, right? That’s because, like a servo, you can control exactly how much
to move your arm.
• Brown Line: GND
• Orange Line: Signal pin, connect to the PWM pin of main board.
• Red wire: VCC
Just like you can control your arms to move to specific positions, we can use servo motors to control the exact position
of objects in our projects. In our Mars Rover, we will use a servo to control the up and down movement of our tilt
mechanism, just like how you can nod your head up and down.
