Welcome to this first weekend project! To do this, you will need An Arduino (all models should be usable) Some LED’s Resistors for the LED’s IR receiver IR transmitter And that is about it. Let’s start with connecting the LED’s. Depending on what you got, this method can vary. I wanted some bigger lights, so I … Read more
After seeing quite a few stepper drivers die, I decided to put some cooling on mine, but instead of having the fan running all the time, I made an extra function for it. This new function will turn the fan on when any stepper driver is enabled, and turn the fan back off after a … Read more
Some time ago, I posted something about a home automation project (click here to read more about how to build this) I was working on, and here it is! It is now working, and put into permanent use in my garage. The next step is to make a bigger version of it, and have some … Read more
These rings was ment for my RepRap 3D printer, but until I got it assembled and working, I could have a bit fun with the rings first. [youtube]http://www.youtube.com/watch?v=Km8_A0UhPYk[/youtube] To make it work, I am using this code. It will fade the ring up and down in different speeds, and also allow for manual control of … Read more
After multiple times having problems connecting external DC power supplies, I started to solder the connectors onto pin headers in different ways. The most stable solution so far is this. And if it is put in like I did, a little in on the breadboard power rail, the surface of the breadboard help support it.
A while ago i purchased a 4×4 keypad on ebay, and actually forgot everything about it. But today it arrived!!! 🙂 After 30 secs on google I found a library for my Arduino and decided to install it. The way to determine is pretty straight forward. You actually just connect to some pins, and see what happens … Read more
I just received a JeeNode with one of these radio’s on board, and then a loose radio to connect with one of my arduino’s. Here is how to connect one to an arduino. D12 D2 – – – – GND D10 D13 D11 – GND 3.3V –
Initial thoughts Got a new mailbox, and I got the choice of putting a switch on the lid or something longer in. My previous one had a switch on the lid, but this time, I am going for something longer inside. How to sense new mail To trigger when new mail arrives, I ordered 5 of these … Read more
Not much to say about it, all it actually is is a LED and a photo resistor inside a tube of heat shrink tubing.
After getting all my Prowl stuff to work, I decided to hack into my mailbox notifier. I found a project from make where Matt uses an Arduino and Ethernet shield to make it happen, but instead, I am using the serial communication, and then wrote my own C# application instead. Another difference is that I … Read more
