Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

For example, I would want to statically allocate that buffer by either passing it into the SSD1306 driver class, or by making the driver class a template so that the compiler can size it ...

Aside from the Arduino UNO microcontroller, LDR, and the bulb itself, the hardware for this setup is pretty minimal: a relay for the bulb, a resistor for the LDR, and some wires to connect ...

The Arduino development board has grown in popularity over the last few years and has spawned a myriad of interesting projects such as auto-lacing shoes, The EyeWriter 2.0, and the Mobile Dance Stage.

GeekDad's very own John Baicthal has joined Matthew Beckler and Adam Wolf (co-founders of Wayne and Layne) to release Make: Lego and Arduino Projects. Just like the other Make: books, it's a high ...

Arduino says these additions allow for more advanced projects. Besides Wi-Fi and Bluetooth, the UNO R4 Wi-Fi has a built-in LED matrix with 96 dots arranged 12x8.

As much as we love the Arduino Uno, it's not the most powerful of hobbyist microcontrollers. Fortunately, the folks in Turin have just put the finishing touches on a 32-bit upgrade with buckets of ...

Renesas’ SVP, Chris Allexandre, said, “We are honored to collaborate with Arduino on their iconic UNO product line. Despite the challenges of this intricate project with a rich legacy, our 5V 32-bit ...
