Servo Motor
For my servo motor lab, I designed a basic circuit on breadboard that connected the servo motor to power, ground and pin 11.
I taped an arrow to the head of the servo motor, so that it moved as the code ran on the Arduino app. My code was fairly simple. I went onto the servo page of the app and added the int servoPin = 11 to which the motor was connected to. And then had the pointer switch at 50 degrees back an forth at a delay(1000) so the arrow moves at a reasonable pace.
I then poked a hole into a circle shaped paper and punched the head of the servo motor through that whole. This would make the arrow point at two directions that were 50 degrees apart.
