“JustAPendulum is an Arduino-based open-source pendulum that measures and calculates the oscillation period to find the gravitational acceleration of the Earth (~9,81 m/s). It contains a homemade Arduino UNO that uses an USB-to-serial adapter to communicate with …

“Hey makers and fabbers out there! Have you ever dreamed of making your own advanced micro-controller board at home and using smd components? That’s the right instructable for you and for the brain of your next project :) And when …

“Hey guys, Welcome to Being Engineers. Hope you all are going great. This will be a short and simple project about how to make a digital clock using Arduino. Previously We have made a binary clock using charlieplexing concept. You …

“In this project i will show how to build a Battery Monitoring System with Over Discharge Protection & Battery level Indicator. If you prefer watching video then i have embedded the same or if you like reading please continue with the …

“The KIM Uno is a portable, software defined dev kit for (retro) microprocessors. But let me introduce the idea of it by going back in time: Back in late 2018 it came to my mind, that I wanted to build …

“Hi! I made this PCB calendar and binary clock with Eagle CAD. I used ATMEGA328P MCU (from Arduino) and 9x9 LED matrix. Dimensions for my board is 8cmx10cm(3.14inch x 3.34inch). Its a bit too small but …

“I’ve been working on an Arduino based smartwatch that could show time, date, alarm, temperature, connect to a smartphone via Bluetooth and show notifications. I had some errors on this baord, but in this tutorial, I’m sharing the …

“Just thought how would a “cool” kit look a like, so I get an altoids tin box eat all the thinks inside and put all necassary parts inside. ;) a new project from good old Germany. I got some of those …

“This project started as a way to create an universal digitally controlled switch mode power supply module base on the Arduino development platform. As I worked on the design, the platform turn out to be an excellent bi-directional DC-DC …

“Finally, the board works perfect. So I could make a 3D design for the case and this is a final product that could end up on Kickstarter. It is a very cheap project, around 15$ for all the parts . On …
