Parking in tight spaces can be challenging, especially when there’s limited visibility. To help avoid collisions with obstacles, this project will show you how to build an Arduino Parking Sensor using an ultrasonic sensor and a buzzer. The ultrasonic sensor detects the distance to an obstacle, and the buzzer produces …

Start your DIY gaming experience with this “Arduino Flappy Bird Project with Dot Matrix.” This project merges the timeless appeal of Flappy Bird with the dynamic capabilities of Arduino and a Dot Matrix display. This article includes hardware setup, gameplay mechanics, and of course, the source code.

A solenoid lock is an electric actuator that converts electrical signals to motion. It is commonly found in electronically controlled doors and drawers. Using the solenoid lock with a microcontroller is easy and, if you’re a beginner, this project is just for you.

For enthusiasts and creators working with Raspberry Pi, the joy of bringing an idea to life is often met with the challenge of maintaining a consistent power supply. This is where SunFounder PiPower comes in to save the day, offering uninterrupted power supply (UPS) specifically designed for your Raspberry Pi …

When working with IoT, it’s often necessary to track a device’s location for monitoring. Global Positioning Service (GPS) remains the number 1 option for large-area tracking. This project will show you how you can use a GPS with an ESP32 and have the location plotted on Google Maps.

For this project, I am using an HC-SR04 ultrasonic sensor for opening a solenoid door lock. Basically, the ultrasonic sensor acts as a proximity detector. A solenoid lock triggers when an object blocks the sensor at a given distance. In addition, a web app can act as WiFi remote control …

This project makes the “dots” on a dot matrix look like they are pebbles in a container. Tilt the device on one side and the dots fall toward that side. The same goes if the device tilts to the other side.

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 …

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.
