In this post, we will see how we can control brightness of LED. I am using 2 inputs for controlling, inreasing and decreasing. One LED for output. Find the code below. //Controlling LED brightness with two input buttons //Code by Deepak Sharma [ElectroMech Lab] const int ledPin = 3;  // LED connected to pin 3 const int buttonUpPin = 2;  // Button to increase brightness connected to pin 2 const int buttonDownPin = 12;  // Button to decrease brightness connected to pin 12 int brightness = 128;  // Initial brightness (range from 0 to 255) const int brightnessStep = 5;  // Step to increase/decrease brightness void setup() {   pinMode(ledPin, OUTPUT);   pinMode(buttonUpPin, INPUT_PULLUP);   pinMode(buttonDownPin, INPUT_PULLUP);   analogWrite(ledPin, brightness);  // Set initial brightness } void loop() {   if (digitalRead(buttonUpPin) == LOW) {  // Button is pressed (active low)     brightness += brightnessStep;  // I...

Recently I made an Arduino Development kit.  Many time, we need to make Arduino project using 1 or 2 input and upto 3 output, for this we have to make connections using wires and assemble the circuit. but by using this kit, we can save much time,
