Update: I’ll add some clarifications after reading comments on various forums. It doesn’t need a 70Mhz ARM CPU, all it does is shift bits into a shift register, that’d be a total waste. There aren’t 16 CPU’s. the slices are designed to be either slave or master, just one ATMega328P chip, they’re chained together, each […]
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 […]
I was looking for a project to do with my Raspberry Pi and found thisInstructable and thought I would have a go at something similar which worked with Google Play Music. I had a rough idea of what I wanted the final item to end up like and was able to get my dad interested in helping me with […]
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 […]
The Memsic 2125 (datasheet) is a two-axis accelerometer capable of measuring acceleration up to plus or minus 2g. It has a simple digital interface: two pins (one for each axis) emit pulses whose duration corresponds to the acceleration of that axis. By measuring the length of that pulse, in microseconds, using the Arduino’s pulseIn() function, […]
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 […]
There are more than 20 models of LEGO®’s Dune Buggy type car, even more than the models in LEGO® Race Car category. Dune Buggy is usually four wheels drive off road vehicle, which would not be used on the road. Now that I got excited on the “dune buggy”, and was also inspired by 1998 LEGO®’s Turbo […]
This sketch shows you how to read the microphone sensor. The microphone will range from 0 (total silence) to 1023 (really loud). It uses the sound level to set a brightness level for the green LED. When you’re using the sensor’s reading (for example, to set the brightness of the LED), you map the sensor’s […]
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 […]
