Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

In this blog, we will learn about how to interface a Passive Infrared sensor (PIR Sensor) or motion sensor with an Arduino. We will also learn about how this sensor works and different parts of it. So ...

In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the usage of ...

Fortunately, both the speed and direction of a DC motor can be controlled via an Arduino microcontroller. Let’s get into details. Direction control A circuit known as an H-bridge may be used to alter ...

If you need a PIR motion sensor with a longer range (up to 12 meters), the Everything Presence One Kit, also based on ESP32-S3, is an alternative, but it lacks battery support, comes with much fewer I ...
