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

The 16×2 LCD And Keypad Shield is easy to use as it works seamlessly with the Arduino “LiquidCrystal” library. With just a few lines of code, you can set up the LCD and show messages on it. Additionally, you have the option to create more complex projects like displaying menu items and using buttons to

Concept: I would like to make a jacket that has a small LCD screen to create subtexts for interpersonal human interaction. The user would use a limited “keyboard” with force sensors and buttons under soft silicone keys to create computer textual subtitles to human interaction (textual emoticons, ie: :P). The dichotomy between personal interaction that

This game is a homage to Ariadne, the maze-generator from Inception 🙂 If you haven’t seen the movie yet – watch this video again after you do (you can also watch it now – it’s not a spoiler, it’s just funnier for inception-vets). The nice thing about it is that it’s a 1st-person game, so when you

These are assembly instructions for the LCD Temperate Shield with buzzer that i am going to be selling soon. Please note, all the photos are my own, but are of one of my Prototype stage boards, and are subject to change, the production boards WILL look different and may have slightly altered layout, but the
