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...

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); ...

Plus, MicroPython compiler and runtime code includes an interactive prompt called REPL (Read-Eval-Print-Loop) that allows executing commands from a desktop computer directly on an embedded platform. The commands using REPL are executed via UART, where the target microcontroller board is connected to...
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...
