NRF2USB is a simple development tool designed specifically for wireless applications that utilize the low-cost nRF24L01+ 2.4GHz transceiver module. The integrated CH55x microcontroller provides a USB ...

Module accepts commands by waving hand over the photocell, or pressing push button switch (depending on module configuration).

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’t ...

Turning an Arduino of virtually any sort into a simple AVR 6-pin ISP programmer is old hat. But when Atmel came out with a series of really tiny AVR chips, the ATtiny10 and friends with only six pins ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

Released over 10 years ago, Arduino UNO is still the best-selling Arduino board, but lacking WiFi in the IoT era is not ideal, so Gianluca Martino, Arduino co-founder and working with the company ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

Discover how the Arduino Opta Pro can be leveraged beyond its industrial roots for smart home and DIY automation. In my article, I share hands‑on insights, practical code examples, and hardware ...

The Joystick module is similar to analog joysticks found in gamepads. It is made by mounting two potentiometers at a 90 degrees angle. The potentiometers are connected to a short stick centered by ...
