this is a robot made with one standard servo and a Parallax thumbstick. the "eyes" can be any LEDs that you want.
Step 1: What You Will Need
PARALLAX 8 pin Thumbstick
AAA battery holder (or AA battery)
LEDs + resistor (im using UV LEDs because I have so many of them)
I got all these parts (plus alot more) in the arduino ultimate starter kit
Step 2: Code First
download the arduino knob code from
and upload to the arduino
Step 3: Setting Things Up
lets wire things up!
place thumbstick upside down on breadboard.
2-AXIS JOYSTICK label should be facing you, but upside down.
L/R on your left should be connected to A0 on your arduino.
L/R+ on your right should be connected to positive.
GND on your right should be connected to ground.
servo positive and ground should be connected to positive and ground.
servo input should be connected to ~9 on your arduino.
Step 4: Decorations
mount LEDs onto the servo head (I used stripboard)
connect LEDs to the battery pack
I hot glued the servo to the pack to keep it small
my battery pack had a switch on it so I used that to turn the lights on and off. you can add your own switch.
Step 5: Enjoy Your Robot
this is a test to control a servo with a thumbstick. it is great practice for beginners and since were using a premade code theres no programming required! this is my first Instructable so tell me how I did
