Designing an Arduino Based Encoder Motor Using a PID Controller

In industrial automation and control, PID controllers have emerged as one of the most reliable control algorithms for stabilizing the output response of any system. PID stands for Proportional Integral Derivative. These three types of control mechanisms combine to generate an error signal that is used as feedback to control the final application. PID controllers […]

How to make a BLE detector with ESP32 and Arduino

A proximity sensor can be described as a switch that detects nearby objects with the aid of light, electromagnetic fields, or sound. Typically, these types of devices are designed to detect nearby objects, and most of these sensors will be used in practical applications. But there are some cases where the object is far away […]

How to Program Arduino via Bluetooth

Arduino Uno, the most popular microcontroller among electronics enthusiasts and students, it’s easy to get started with embedded systems using the Arduino, but one downside of the Arduino is that it needs to be connected to a computer using a USB cable to upload code, as it’s already done on the There is no onboard […]

Build an Ultrasonic Levitation Device Using Arduino and HCSR04

It’s very exciting to see something floating in the air or in free space, which is what the antigravity project is about. The object (essentially a small piece of paper or hot glue) is placed between two ultrasonic transducers that produce sound waves. Objects float through the air due to these seemingly gravity-defying waves. Not […]

How to Build a Function Generator Using Arduino

Every engineer who likes to tinker with electronics at some point in time wishes to have their own lab setup. Multimeters, clamp meters, oscilloscopes, LCR meters, function generators, dual-mode power supplies, and autotransformers are the minimum equipment for a decent lab setup. While all of these can be purchased, we can also easily build some […]

DIY a smoke detection system based on artificial intelligence sensor

This item is a DIY project only and does not replace a certified smoke detector. The sensor system developed by this project is just a complement, implementing sensor fusion to detect smoke and reduce false alarms. background Smoke detectors have saved many lives. For example, fire victims fell by more than 48% in France from […]

Tutorial to Build an Arduino IR Remote Decoder

IR (Infrared) communication is a simple, low-cost, widely used wireless communication technology. Infrared light is somewhat similar to visible light, only with slightly longer wavelengths. This property of IR makes it imperceptible to the human eye, making it ideal for wireless communications. There are many applications that need to decode the IR signal in order […]

Tutorial for making a hedgehog robot

I made a robot hedgehog that can move around (passer) and browse up to 5 different places. background Each hedgehog has to walk several miles this night in search of food. Design is a game that educates the general audience, mainly children, about the current status of hedgehogs in cities and the current conservation of […]

Build a simple rain detection system with Arduino

A simple rain detection system can be easily built by interfacing an Arduino with a rain sensor. The sensor will detect any rain falling on it and the Arduino board will sense it and can perform the desired action. Systems like this could be used in many different fields, such as agriculture and automotive. Rainfall […]
