You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor or to display it on an LCD ...

The Arduino UNO R4, released in two versions last year, supports the CAN bus in terms of hardware and software. In this article we look at some handy CAN modules, an experimental setup, and the basics ...

This repo contains the class materials for the "Arduino Basics" class that I teach at General Electric. It will cover multiple examples intended to teach basic concepts needed to program for Arduinos.

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

LED Blinking: We use an LED (Light Emitting Diode), which is connected to the Arduino via a resistor. The resistor limits the current that flows through the LED to prevent it from burning by too much ...

Discover the ultimate IoT powerhouse—Arduino Nano ESP32! Unleash creativity with C/C++ in Arduino IDE, or embrace MicroPython's simplicity. Wi-Fi, Bluetooth 5 LE, 16 MB Flash, LEDs, all in a compact ...

VCC is the power supply pin of the soil moisture sensor that can be connected to 3.3V or 5V of the supply. But do note that the analog output will vary depending on the provided supply voltage. GND is ...

If you're looking to make yourself somewhat more productive on this lazy weekend, and you've got an Arduino or two collecting dust, we've got just the thing to add line after line to your dwindling to ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...
