Let’s learn to adjust an LED’s brightness using one of the Arduino’s analog outputs. You’ve probably already learned how to use Arduino’s digital i/o pins to send HIGH and LOW signals to an LED, but some of these pins are capable of simulating a signal somewhere in between. These pins are labeled on the Arduino Uno […]
You’ve all probably had a chance to do that classic high-school experiment: pop bottle rockets. You’ve probably taped on some fins, a paper nosecone, and presto! You launch a “rocket” that is loads of fun- and watched it fall down from the sky. Why stop there? Here, I’ll show you the basics of building the […]
Hi there, This is my contribution to the Space-Contest. There are some ISS-Pointer around the WWW. Some of them use several PSUs and/or quite big motors. My goal was to build something cheap, looking cute and a little bit badass – all powered with only one 5 Volt PSU. If the GIF and/or the embedded Video don’t work, here […]
Yes, I know what you’re thinking, this does seem a little overkill but first of all, you’ll never have to worry about stubbing your toe again and second, it makes walking up and down your stairs so much fun, i found myself going upstairs for no reason just to watch the lights follow me. I mean it […]
In this Instructable I will be taking you through the basics of creating your own 6 keyed macropad, controlled by an Arduino. I will be taking you through what you need, how to assemble it, how to program it, and how to improve it or make it your own. After much research, I couldn’t really […]
In this project we’re going to show you how to make your mailbox more fun and usefull. With this mailbox, if a letter is in your mail you have a nice light wich shows if you have mail, and you can controll this mailbox with bluetooth to automaticly throw away or keep your mail, with […]
The story of this clock goes back a long way – more than 30 years. My father pioneered this idea when I was just 10 years old, long before the LED revolution – back when LED’s where 1/1000 the brightness of their current blinding brilliance. A true innovator, he coded in assembly language and hand […]
In today’s Instructable, I’ll show you how you can use a generic RF module without a microcontroller which will eventually lead us to build a project where you can convert an IR Remote of any device to a RF Remote. The main advantage of converting an IR Remote to RF, is that, you don’t have […]
With this ‘Test Fixture’ and provided software you can test virtually any MCU with as little as 4 digital I/O lines (even only 2 is possible, all be it tricky) for project suitability and performance. When I start a new project I don’t like hooking up a lot of wires before making any progress on […]
Introduction / Why this project In 2016 I build my first fish feeder, see Fish Feeder 1. The feeder worked fine for more then half a year. After that period the servos were worn out, causing the program to halt, without sending an error-mail. Oops. I didn’t had the time to correct this fault, because the aquarium […]
