231a-ag project proposal
Preliminary Project Proposal
Idea
- Using Will O'Brien's "RGB Combination Door Lock" idea, and combining it with Chris Kirkham's "Alarm Triggered Light Bulb".
- The ultimate goal would be to create an alarm clock that goes off at a preset time, and in order to shut it off, you would have to enter a preset combination of RGB colours.
- Why? I use my cell phone as an alarm in the morning, and find that flipping it open, and finding the right button to turn the alarm off gets my brain working a bit, and then I feel more awake. Having to punch in a preset combination of RGB colours on a keypad would wake me up even more... I hope.
How?
- In the alarm-bulb project, Kirkham took apart his alarm clock, and discovered there are were contacts that provided "low-voltage DC power" to turn on the radio.
- Could I use this power to power the combination "lock" needed to turn off the alarm?
- I'd then use the idea from the lock... ie. when the correct code is punched, "unlock the door", aka stop the alarm.
Materials
Unfortunately, I'd probably need to spend more than $20, but here's the preliminary list, anyway.

- Triple Output LED RGB (quantity TBD)
- various transistors
- various resistors
- various diodes
- an alarm clock
- small breadboard (I think?)
- more things TBD
Procedure
No idea, although Will O'Brien's project has a pretty thorough explanation of how to hook up the button keypad/LEDs. And Chris Kirkham's project includes some code I can look through and a good explanation of what he did. Both also have a lot of diagrams I would probably find very useful.
