Measuring an object’s weight can sometimes be part of a bigger project. And unless you have a good reason, you wouldn’t want to use an analog weighing scale. A digital weight sensor is easier to interface with, not to mention its accuracy and durability against an analog weight sensor. In …

This ESP32-powered project allows you to write messages to a MAX7219 LED matrix display using your smartphone. Scaled up, this can be used as a WiFi message board for schools or signages for businesses.

For this article, I will show you how to use an ESP32 microcontroller as a magnetometer – a device that measures the direction and strength of a nearby magnet. In the absence of a nearby magnet, the device detects the Earth’s magnetic field. Hence, a compass is a type of …

Sponsored Post from NextPCB PCB manufacturers often present their customers with an IATF 16949 certificate on top of known certifications such as UL and ISO. What is this certification and why should we care about it?

In this article, I will guide you to the steps on how to build a WiFi servo controller project using the WeMos D1 Mini ESP8266 breakout board.

I believe what makes Arduino popular is how it makes microcontrollers easier to use. I remember the time when I have to spent hours coding a project and then spend money on programming hardware. Arduino has its limitations, but the platform helps create tons of electronic projects even for non-engineers. …

The ESP32 has become one of my favorite microcontrollers as it’s compact, relatively cheap and contains 125% higher memory than an Arduino UNO.

It’s 2020 and sending SMS is now an old technology. But such technology remains to be a cheap and indispensable way to communicate over long distances. In this article, I will share how I send SMS with the Raspberry Pi.

If you’ve been using Arduino, you might have used or have heard about the ultrasonic sensor. Most of us use it for level/distance measurement while some use it to detect an obstacle in front. What most of us don’t know is that there is an underlying flaw with the ultrasonic …

Introduction This week’s Arduino project is a classic one and ideal for beginners. Here I will be showing how to build a simple clap switch for a RGB LED strip. Basically, a microphone captures the sound of the clap and converts it to a voltage. The Arduino processes that voltage …
