This is my P-CNC plotter which is laid out and disguised as a quadruped robot. Today, I’d like to share how I made it. It was quite simple, no 3D printer required, just need my meticulousness, care and a little patience. Please check the brief description and how P-Plotter works in the video below before […]

Display Your Photo on OLED Display
The tiny 0.96 inches OLED display is the most popular among the Arduino fraternity for displaying data like room temperature, humidity, and text messages. Have you ever thought of displaying your own photo on the display! Yes, it’s possible. In this Arduino-based project, we learn to display any photo on this small display. The above […]
FOOT PEDAL ACTIVATED WATER TAP
Greetings everyone! We hope you are in good health. We live in a world where any form of physical contact between two human beings is starting to pose serious health issues. Keeping this in mind, a while ago, we had worked on an automatic water tap using an Infrared sensor to detect the presence of […]
Pinewood Derby Car Scale With Center-of-Gravity (CG) Calculation
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 […]
Electronic Dice With Arduino Nano
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 […]
Blood Oxygen Heart Rate Meter
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-… […]
How to Make Powerfull Laser Engraver
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 […]
Arduino Based Counting Tree for Children
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 […]
How to Drive 4-Digits Seven Segment With Arduino Using Just 3 Pins
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 […]
Basic Arduino MIDI Arppegiator
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 […]
