Yes-No Thing

An electronic excise and a table piece made for a themed party. A basic exercise in physical input-output using a servo logic. A breadboard with a servo, joystick, arduino nano, and a usb-to-serial adapter all sitting on a usb charger. A very short arduino code.

// arduino nano - servo - joystick

// servo input -> D2
// joystick axis -> A1

#include <Servo.h>
Servo myservo; // create servo object 
int pos = 0; // servo position
const int joyH = 1; // pin A1 for joystick axis
void setup() {
 myservo.attach(2); // attaches the servo on pin D2 
 Serial.begin(9600);
}
void loop() {
 pos = analogRead(joyH); 
 pos = map(pos, 0, 1023, 0, 180); // rescale joystk value
 myservo.write(pos); // command the servo
 delay(15); // time for servo mvmt
