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&… ...

When the button is pressed the Arduino board will put pin 2 in HIGH state, meaning 5V on pin 2. This voltage is used to drive the transistor that will switch ON the relay and the load (in our case the ...

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… ...
