An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

Here is a very simple and easy robot named Line following robot. The line follower robot is a basic robot that follows a specific path indicated by a line having some particular width. This circuit ...

These three 3D printing projects are far from the only prints I’ll do on my Arduino journey, I’m sure. I’m already looking for the next prints to do, and even working on making some of my own. But, ...

Recently, I wanted to build a Sleepy-LED Eye as an add-on indicator for a small personal project. My idea is a near-replica of the iconic breathing pattern used for the “sleep” indicator in Apple ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

A way to apply the output of certain sensors to a TTL/CMOS-level iput on a microcontroller. Sensor must have an NPN output stage that can support a pullup to its power rail. With just a few components ...

In safety-critical applications, trouble-free operation is enormously important, especially for microcontrollers. By law or in companies from the automotive, health or production industry, there are ...
