The Arduino Leonardo looks like the UNO and is in many ways similar to it. But because it is based on the ATmega32u4, it has an advantage with built-in USB communication. This allows it to emulate computer peripherals like mice and keyboards, making it especially useful for projects involvin...
void setup () { Wire.begin (42); Wire.onRequest (requestEvent); // interrupt handler for when data is wanted } // end of setup void requestEvent () { Wire.write ("ABCDE", 5); } // end of receiveEvent void loop() { } This slave always returns 5 bytes. Example master: #inclu...

Open Arduino IDE and create a new file. Afterward, copy the following code into the new file: #define SERIAL Serial #define sensorPin A0 int sensorValue = 0; float tdsValue = 0; float Voltage = 0; void setup() { SERIAL.begin(9600); ...
void loop() { Serial.print("State of button 1: "); Serial.println(digitalRead(button1); Serial.print("State of button 2: "); Serial.println(digitalRead(button2); } CALCULATING THE VALUE OF THE RESISTOR The value of the resistor depends on two factors. First is consumption, waste of en...

One of our favorite Arduino-compatible boards is the NodeMCU, pictured below. We love it so much thatwe called it the Arduino-killer. It's tiny, has Wi-Fi built-in, and can be bought for as little as $3. It's perfect for compact internet-of-things and home automation projects. Mean...
