I recently needed to measure how different materials affect light transmission for a gardening project. I decided this was the perfect opportunity to try out the new logic level converter to run both a 5v LCD and a 3.3v light sensor on a single i2c bus. I used the following parts in this project: Arduino […]

What it is… Type: Graphical (128×64) monochrome LCD with LED backlight Interface: Serial / SPI This is a good time to read the datasheet Available from: Adafruit, of course! Introduction: This mini-tutorial will go through the process of setting up a ST7565 LCD. These LCDs are graphical which means they can display pixels, not just
There are a lot of Twitter feed readers around the Web that use Arduino AND a PC to display twits on LCD displays or whatsoever. Then, I decide it was the time to design a solution for performing the same job WITHOUT A PC, and here’s the project. In a simple equation: Arduino + Ethernet

I’ve made an iButton garagedoor opener and logger. On a Dutch (kind of) eBay (www.marktplaats.nl) I found some iButtons and readers very cheap. I had no idea what to do with them, but I bought them anyway. My garage opens with a push on a button, so it must be possible to get that working

I have always wanted to do an instructable, but I never had a somewhat original idea that hasn’t been done a million times, or something that had no means of building. I have some friends who recycle aluminum for money and after seeing the large bags of an unknown amount and weight of uncrushed cans, I decided to make a machine
