“This article describes how to use an Arduino Leonardo or Arduino Micro to make up to three classic console joysticks (e.g. Atari 2600, ColecoVision, and possibly others) available to a modern computer (e.g. Windows PC, Mac, or Linux …
“After VGA Pong, I have reproduced another color version of classical game for Arduino Uno and a VGA monitor: VGA Snake!”
“In this project I will demonstrate how a RF FM transmitter works and how this principle compares to the older AM. I will also show you how to build a simple and crude FM receiver which can even sometimes let …
“I needed to take temperature vs. time measurements for a piece of research equipment in order to determine how much time in advance someone should start prepping before they actually intend to use the equipment. In this case, prepping involves …
“The original version of my hot tub controller starting having some problems which ended up being caused by an animal chewing through the control cables. I never liked having that huge bundle of cables running all the way across the …
“Make your own mini light seeker robot.”
“The story of this motor shield is that I wanted to make a robot for my multifunctional brainwave controlled system and I decided to share this with you. It’s a very simple circuit I used the L293D IC that …
“I like LiFePO4 batteries. They have a rather flat discharge at around 3.2V, which is ideal for powering 3.3V devices without a regulator. You can also use them in devices that take 2 standard AA cells by using …
“This Instructable documents how to create a simple heart rate monitor using Photoplethysmography with an IR phototransistor via transmissive absorption using the Arduino to process the pulsatile data and display live results via a TFT screen. To use the source …
“I was bored so I started to fiddle around with transistors. The reason this became a LED fade and constant current circuit is just because the parts were at hand and lights in different colors is always cool. Please see …
