Hey guys and welcome back, This is my DIY Security Cam which is made from an ESP32 connected with a 5V Charger circuit that converts 240V AC into 5V DC for ESP32 to run. The goal for making this project was to make a cheaper alternative to the existing WIFI Security Camera. Also, huge thanks […]
Some of my favorite projects are making tools that I can use with other hobbies. I am not a master woodworker by any stretch, but I do enjoy it and have created several jigs with my 3D printer that have been useful. If you use a miter saw at all, you know the struggle of […]
In this instructable I will show you how to make a basic MIDI instrument using an Arduino Uno. This instrument plays three notes (a triad) in a row. Using the different potentiometers, you can move up and down the notes as well as up and down a scale. You can also control the delay between each […]
Hello every body, Welcome to this tutorial. In this tutorial we gonna talk about How to drive a 4-digits 7segment with Arduino using minimum pins. To do this we are going to use very popular IC called 74HC595. It’s a 8-bits shift register that has 8 separate outputs. the advantage of this chip is that […]
Counting can be a fun task for young children. Children as young as two may start saying numbers in no particular order. A lot of parents start teaching their kids numbers by counting objects around their home. For example, snacks could be counted as the child eats them or toy cars on the floor could […]
Hello Guys Whats up, In this instructable, I am making an Awesome mini laser engraver from old DVD writers. It’s very interesting project for any electronics hobbyist & Engineers. You can use this laser engraver machine to make any kind of design, logo, art on the surface like WOOD, MDF, PLYWOOD, VNYL Paper. Thank You […]
In France and some other countries playing the flute is included in music lessons at school. This project is to share a possible solution for children or music lovers with limb differences and agenesis to play flute. Basic Idea: Use an Arduino board to make a circuit that if a button is pressed then the […]
This instructables show how to use MAX30102, XIAO and a tiny display to build a blood oxygen and heart rate meter. Step 1: Sensor & Algorithm This project use Maxim Integrated MAX30102 Biosensor to detect pulse oximeter and heart rate. However, the official sample is not so accurate, so will use the MolecularD algorithm instead. Ref.: https://www.instructables.com/Pulse-Oximeter-With-… […]
A key factor when building a pinewood derby car is its weight. The Boy Scouts of America and other organizations specify a weight of no more than 5 ounces. To improve performance many builders will add as much weight (mass) as possible up to that maximum allowable weight limit. What is often overlooked is the […]
The electronic dice presented here, built around a tiny Arduino Nano board, mimics the dice we play in different games like snake and ladders the most popular. Plastic and wooden dice are subject to wear and tear with time and might show biasing toward a specific number defying theory of randomness and the player as well. As […]
