Hello guys,br Welcome to Learning Microcontrollers youtube Channel,br br Guys I have also compiled course on Udemy as well. Where you will learn under my direct supervision in a more supervised way.br Here is the links to the courses I have on Udemy, By taking any of these courses you will be supporting my channel aswell.br This will help me to make more videos with better hardware in the future. I hope you look forward to it.br Courses Links:br br 1- 2- 3- 4- 5- #electronics #arduino #arduinoproject #project #microcontroller #circuitdiagram #circuitdiagram #simulator #simulation #proteus #proteus8 #pic16f877a #arduinotutorial #electronictutorial #embedding #embeddedprojects #embeddedsystem #embeddedprojectcenters #embeddedsystem #diy #diycrafts #diyideas #diyproject #diyarbakır #toggle #toggleswitch #switch #bluetooth #hc05 #wireless br br br br Arduino Code:br br br br ARDUINO UNO ADC is 10 BITbr 2^10 = 1024 means 0 - 1023 br int ldrval;br void setup() {br Serial.begin(9600);br }br br void loop() {br ldrval = analogRead(A0);br Serial.
