HAND SANIDISER DISPENSOR USING LDR

THIS IS THE PROJECT MADE FOR THE CURRENT SITUTATION COVID-19 PANDAMIC. THIS HELPS IN DO NOT TOUCHING THE SANIDISER TO PRESS THIS AUTTOMATICALY WHEN THE LDR SENSES DARK. THE SERVO OR MOTOR TURNS ON FOR A SECOND. I AM ALSO MAKING PCB FOR THIS TO MAKE THIS AS SMALL CIRCUIT

1.) ARDUINO (ANY BOARDS)

2.) LDR

3.) 10K RESISTOR

4.) MOTOR OR SERVO

5.) POWER SUPPLY (5-12 VOLT)

6.) WIRES(JUMPER)

7.) BREADBOARD

8.) RELAY OR RELAY MODULE

TO MAKE THIS PROJECT WE NEED TO ASSMBLE THE CIRCUIT SEE THE CIRCUIT DIAGRAM ABOVE . CAN ALSO USE IR OR ULTROSONIC SENSOR

THIS IS THE CODE UPLOAD THIS CODE (COPY AND PASTE)

// AUTOMATIC SANIDISER DISPENSER USING LDR
const int relayPin = 13; const int ldrPin = A0;

void setup() {

pinMode(relayPin, OUTPUT); pinMode(ldrPin, INPUT); }

void loop() {

int ldrStatus = analogRead(ldrPin); if (ldrStatus <= 80) // THIS MAY CHANGE ACCORDING TO YOR BRIGHTNESS OF LIGHT { digitalWrite(relayPin, HIGH); } else { digitalWrite(relayPin, LOW); } }
