This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

Don't worry, the coding is simple enough to understand even without prior experience. An Arduino is a much better choice than ...

Ever thought of using touch sensors on your projects but didn’t because it would be too much work? [Paul Stoffregen] proves that it can be pretty easy if you use the CapSense library for Ardu… ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...

Arduino’s latest innovation, the Nicla Sense Env, is a compact yet powerful sensor node designed to enhance environmental sensing projects. This new addition to Arduino’s portfolio empowers ...

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware ...

Surprisingly, there are five I/O pins in a convenient eight-pin DIP package, ample for the most astounding projects. I’ve used a bunch of ATtiny85s for some funny projects (arguably, they’re not so ...

The magic lies in Arduino's Modulino nodes, which consist of various sensors and actuators that connect to the UNO R4 WiFi board. The Plug and Make Kit is a complete package to get started. Inside ...

Not every project you make can fit into the Raspberry Pi's 26 GPIO pins, especially the more advanced applications like multi-sensor weather monitors or home automation systems.
