This project will utilize the Arduino Uno micro controller, a micro servo, and 4x4 matrix keypad to create a system in which the keypad will accept a character press from the number pad and use that number to set a specific servo position.
What you will need:
- Arduino Uno
- Micro Servo
- 4x4 matrix Keypad
Step 1: Connect the Keypad
Follow the diagram shown and wire the keypad to the pins on the Arduino. I have the keypad wired to Digital pins 2 - 9.
Step 2: Connect Micro Servo
Follow the diagram shown and wire the micro servo to the pins on the Arduino. The servo needs to be wired to GND and 5V, and I have it wired to Digital 11.
