If you are just starting out in electronics, you need tools. But it is hard to build all your tools. Even though we see a lot of soldering station builds, you really ought to have a soldering iron to ...

Each Arduino capacitance test relies on a property of resistor capacitor (RC) circuits- the time constant. The time constant of an RC circuit is defined as the time it takes for the voltage across the ...

The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, making it safe to use with any liquid. The ...

[Marcus] has written up his experiences using the AD7746 capacitance sensor. He used the SparkFun breakout board in conjunction with an Arduino. The available Arduino code wasn’t that great so he ...

Arduino based projects are quite complicated and is no cake walk for beginners in this field. Interfacing a tablet with the microcontroller is a daunting task. Let see how its done here. Arduino based ...

Makers and hobbyists that are looking for a capacitive touch sensor for a project, might be interested in a new touch sensor board called the EasyTouch. The EasyTouch capacitive touch sensor can be ...

A simple, beginner-friendly C++ library that brings capacitive touch sensing to the Arduino UNO‑R4 Minima and UNO‑R4 WiFi. It abstracts away all the low‑level CTSU, DTC, and interrupt details so you ...
