The ESP8266 microcontroller is a favorite among makers for creating affordable, Wi-Fi-enabled sensor projects. Pairing it with a DHT22 temperature and humidity sensor is one of the easiest ways to get ...

Build a drone detector, pool thermometer, and pantry tracker with your Raspberry Pi this weekend ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

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 ...

[HankDavis] sent along this link to a video showing a tutorial on how to make touch sensors using a “darlington pair”. In the video we are taken through the idea and how we’re going to construct it.

Raspberry Pi enthusiasts looking to build projects including an RFID scanner may be interested in a new tutorial by Instructables member Xeiverse to create a Raspberry Pi RFID Scanner with ease.

A simple AVR microcontroller based circuit that can detect when you touch a metal probe connected to one of the mcu inputs. A simple AVR microcontroller based circuit that can detect when you touch a ...

We talked to engineers whose views on a low-cost, sensor-bridge-cloud solution for gaining better insight and control over operations underscore the tradeoffs in innovation vs. standardization. Ask ...
