The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...

When comparing the Raspberry Pi and Arduino, it's no secret that the Pi is undoubtedly the more powerful board. It is, after all, a single-board computer (SBC) that can run a fully functional ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

A maker shared an electronics project on Digikey that explains an automatic system for recognizing and organizing resistors using an Arduino Uno Q. Zach Hipps did the work and looked for methods to ...

Arduinos are helpful but some applications require more than what Arduinos can provide. However, it’s not always easy to make the switch from a developed ecosystem into the abyss that is hardware ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

FPGA guru [Max Maxfield] recently took a look at the XLR8 (pronounced accelerate) board from a company called Alorium. On the surface, it looks like another Arduino UNO clone. But instead of a CPU, it ...
