The LilyPad Arduino USB is a sewable Arduino compatible board with a built-in LiPo battery charger. It connects via microUSB cable to your computer, which means that, unlike regular LilyPad boards, it ...

Tutorial how to build a USB-chargeable temperature / humidity / pressure sensor node in a power bank case which transmits the data via 433MHz to a receiver whose serial protocol is MySensor compatible ...

In this short video we will show how to use an Arduino development board as a USB to TTL Converter (also known as COM or RS-232) converter.

All three push buttons are pulled high using 10K pull-up resistors. Note: It is necessary to upload a boot-loader on ATtiny85 to program it using the USB. So follow our previous tutorial on How to ...

The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature isn&… ...

We are excited to introduce the all-new Arduino Nano ESP32 – a powerful and versatile IoT development board that opens up a world of possibilities. This feature-packed board combines the ESP32-S3 with ...

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 (RPM). You don’t need much… ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...
