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.

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

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 …

Flame sensors are found from the simplest gas stoves to huge industrial plants. There are different types of fire sensors -- some cheap, some expensive. Yet they’re all built for one single purpose: detect fire. In this article, I will guide you on how to build a flame sensor with …

In general terms, a magnetometer measures the magnetism of objects or places. In fact, a compass is a type of magnetometer. This project demonstrates how to use the HMC5883L magnetometer as a compass with an Arduino microcontroller.

This project demonstrates how to read data from the DHT22 temperature and humidity sensor and send that data to the web using an ESP8266 via MQTT.

This project demonstrates how two bluetooth modules connect with each other. I’ll be featuring DFRobot’s Input Shield V2 as the transmitter/controller and Seeed’s ShieldBot, which was seen on my Bluetooth RC Car project, will act as the receiver.

To kick off 2019, I would like to create a series of Arduino Robot projects that anyone can learn how to build. The first part of the series is the popular obstacle-avoiding Arduino robot.

Wouldn't it be cool if you build your own card login system just like in hotels? Because RFID modules are now easy to get, this is now very possible. This Raspberry Pi RFID project of mine is a simple login system that reads cards and tags. Every time a user …

This project demonstrates how to send data to ThingSpeak using a SIM800L breakout board. The data will be coming from a BMP085 atmospheric pressure sensor and will be using the SIM800L GPRS connection to publish this data to ThingSpeak.
