TweetSweets is in no small part inspired by Labby’s twitter-enabled candy machine
Hell, it even uses the same dispenser! Shameless.
I’ve also cobbled together bits of code from other sources, including:
- a bit of Scott Fitzgerald’s PhotoResistor code from the Arduino Starter Kit book
- Twitter Processing sketch based on RobotGrrl.com ‘Just a simple Processing and Twitter thingy majiggy‘ that I used for ‘I Am Iron Man’
- Webcam code from Samuel Cox’s WeddingBooth
- Yonas Sandbak’s PostToWeb class
Funny thing is that this project didn’t start out involving sweets at all. Originally, I had planned to use NFC cards to allow people to quickly tap in, have a picture taken and then manipulate that image once it was on the server.
Somewhere along the line I must have gotten hungry!
Put the code above together and this is the flow you get:
- User1 sends a tweet with #givejacksweets
- Processing searches for the hashtag, sends a tweet thanking them and passes ‘sweets’ to Arduino
- Arduino activates sweet dispenser for 0.5 seconds
- Photoresistor detects when User2 collects them, and passes to Processing
- Processing takes a photo of User2 and tweets this to the User1
- User1 and User2 both smile :)
A bit of fun, and more Arduino/Processing lessons learnt.
Technically, I don’t doubt that this would appear far more streamlined using a Raspberry Pi but I don’t have one! :)
