Use an ESP32 Cam and a passive infrared (PIR) sensor to create a motion-activated security camera that posts photos to a Discord channel.

This is another one of my series of unusual clocks. The time is displayed on the WS2812 LED strip containing 34 LEDs

How to make balancing LED dot using WS2812 LED strip and MPU6050 accelerometer and gyroscope module.

Very simple station that shows: Temperature, Humidity, Heat index, Carbon Monoxide, Alcohol, Carbon dioxide, Toluene, Ammonium and Acetone.

An accurate clock with date displayed on a 16x2 LCD using just the Arduino, the display and few buttons. No RTC module required.

Use a ratiometric linear Hall effect sensor to build simple magnetic field strength meter.

You'll learn how to create an automation system to communicate 3 Arduinos via RS485.

This is a simple square-wave generator that basically uses the TimerOne library allow you to generate a PWM signal at pin 9.

Not enough fingers to play clarinet? With this project you can delegate solenoids to push two side-keys. Awkward fingerings whaaat?

An Arduino based Christmas tree decoration using basic electronic components and recyclable material.

In this project it is presented 1-dimensional version of the classic game ‘Pong’ made with NeoPixel LED strip.

Relay VS Transistor.

Discharge a fully charged Lithium-Ion cell through a resistor while measuring the current flowing through the resistor to calculate capacity

Visualizes the peak of frequencies with different bars on 8*8 led dot matrix using Arduino Nano.

A simple setup using an Arduino Nano and an LCD Keypad Shield to set the date, time and alarms for a DS3231 Real Time Clock (RTC).

An easy DIY lamp which can change its colour like a chameleon. Just show it a different colour & see the magic.

This is a cool way to measure your hearing. Hope you enjoy it!

So far I was controling those matrixes with multiplexing. In this video I would use MAX7219 chip to do it

How to make Arduino based Home Appliance Control Using Android Application | Home Automation Project

A very simple but useful device for your lab.

Make a DIY robotic bat that flaps its wings whenever someone walks by out of Arduino, off-the-shelf DC motor, Lego, and 3D printed parts.

Today I will show you how to make eating robot with Arduino Nano. This project I made for my daughter. It's very easy with cheap materials.

This device serves for accurate measurement of small resistances in the range of 0.1 ohm up to 50 ohms.
