Ldr Arduino Schaltung. Circuit diagram of ldr and led. Arduino project 2 ldr photoresistor and led.
The photoresistor or ldr is a resistor that varies its value according to the light falling on it and therefore it can be used with arduino to create innovative and more complex projects. Posted on july 26 2019 april 24 2020 by buildcircuit. The value of ldr is printed to serial monitor.
Testing the code for the arduino ldr sensor.
Arduino project 2 ldr photoresistor and led. Connect the other leg of the resistor to pin number 11 digital pin of the arduino. One leg of the ldr is connected to vcc 5v on the arduino and the other to the analog pin 0 on the arduino. The value of ldr changes with the light exposed.
