Ladies and Gentlemen, I bring to you - the Arduino Combi-button Lock!!
This example will cause only an LED to come on when the passcode is entered, but other features can easily be added, such as a servo, motor etc.
If you do not wish to use buttons, there is an alternative TouchOSC version for Android or iPad/iPhone/iPod touch. Just skip step 4.
This is an entry for the Microcontroller contest. If you think it's awesome, be sure to vote!
So let's get started!
Step 1: Components - What you will need
-> An Arduino board - in my case an Arduino UNO I purchased from oomlout.co.uk. I bought the starter kit, and I would highly recommend it - go check them out!
-> A USB type-A to USB type-B cable
-> The Arduino IDE - download from arduino.cc
-> A breadboard
-> 4 x push buttons/switches
-> 4 x 10k ohm resistors
iPhone/iPod Touch OSC Controlled version:
-> TouchOSC app ($4.99 on AppStore, and I believe it is free on Android)
-> TouchOSC layout editor
-> The Processing IDE - download from processing.org
