Introduction: Connect and Use Joystick With Arduino
A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling.
Joysticks are often used whith Arduino to control robots.
Step 1: Step 1:You Will Need
- Jumper wire
- Joystick Module
- 4 resistor 220hom
- Arduino UNO
- 4 leds
Step 2: Step 2: Connect Joystick Module to an Arduino Uno
Joistic Module----Arduino
wire yellow y--------pin A0
wire brown x--------pin A1
wire wite bt----------pin 8
wire red vcc---------5v
wire black gnd------gnd
Step 3: Step 3: Connect Led to Arduino
Step 4: Step 4:THE CODE

/*Arduino Micro Input Pins */
int IUP=A0;
int ILR=A1;
int MID = 10; // 10 mid point delta arduino, use 4 for attiny
int LRMID = 0;
int UPMID = 0;

digitalWrite(DWN, HIGH);
digitalWrite(UP, HIGH);
