Have you ever felt like not wanting to celebrate Halloween? Or too lazy to open the door and hear “trick or treat” a thousand times? Well, if that’s you, we offer the perfect solution without losing the spirit! This project is an automatic machine that works as a candy dispenser by detecting when a hand […]
This instructable shows how to build a shield to connect devices that send MIDI signals (e.g. a masterkeyboard) to an Arduino. The basic schematic is derived from: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1187962258/ Step 1: The schematic Basically the schematic is just an optocoupler with some resistors to decouple the MIDI device from the Arduino. Note that the DIN connector […]
As promised, this week brings another communications tutorial! In this video, we’ll use both the serial and processing knowledge that we gained last week, plus an I2C enabled temperature-sensing IC. We’ll use processing to generate a pretty room temperature display on your computer screen. If you are new to processing, they have an excellent […]
This is the first bicycle accessory gadget I made with Arduino. It’s a pattern-based backlight attached to the back-bag mounted on the bicycle luggage compartment. I’m riding an electric bicycle which can speed up around 24km/h at maximum. But I had fallen already three times and one of the incidents makes me go to the […]
MIT has developed a fantastic visual programming language called Scratch. It is also an amazing learning tool for children, because it is simple, cute, and by providing interaction with the real world by a board called “Scratch Sensor Board”. This Instructable shows the development of a shield for Arduino that can interact with Scratch and replicates the […]
Setting up an Arduino on a breadboard has become a process I have grown to love. Within a few minutes you can have a fully working Arduino platform to work with as you will see in this tutorial. There have been several occasions when I was at school and quickly put together one of these […]
With this device you’ll be able to: take pictures from anything you can sense or detect: – movement – sound – … You don’t need to modify your camera or flash for this. It’s compatible with the old High Voltage flashes and the new TTL ones. Why I did this project? A friend of me […]
So first off , I am a student and wanted to pick an instrument , but the problem was that I was not sure that “would I be able to do it ?”. So, I thought to clear my base first and got an Idea to make a Piano using Arduino. This piano is a […]
This post is based on the work made previously by tomek in wiring LCD displays using 4 bits. The basic idea is to group the 7 pins that are needed to drive the LCD in only 3 using a shift register. This is a cheap alternative to serial LCDs. The schematic shows that wiring the […]
This project consists of an interactive Arduino-based Halloween decoration referring to a witch cauldron. As you position your face in front of the cauldron and you get close, the eyes start moving around. At the same time, when there is very low light in the room the program turns on a LED light located in […]
