Introducing the “ijunk” – the junk mail iphone / ipod dock
“the best thing to happen to iphone since iphone 5”
When an iphone or ipod is docked it activates a junk mail delivery mechanisim. This was a really project with no apparent purpose but gave me the opportunity to use a physical imput to create a digital action in the ardino code and then return a physical output. The physical circuit uses a tip120 transistor which acts as a electronically controlled switch allowing the motor to draw power from an independent power supply. This is important as if the motor were to be connected directly to the arduino it could fry the arduino’s chip. The code i used was a version of the button example featured in the continue reading section of this post. Ideally if I had more time I would have better integrated the iPhone charging into the arduino and have it actually recognized when it was being docked, rather than just using the phones casing to connect the circuit via contacts.
Some of the tutorials and useful sites I found and used are here:
