Hello all,
This is the first electronics project I've ever done aside from some basic circuits in high school. I've forgotten most of what I've learned, so I'm looking for some help. The goal is to make a circuit consisting of a switch, some LEDs, a buzzer, and possibly a microcontroller. When the switch is flipped, the LEDs will blink and the buzzer will play a specific tune (I assume due to the microcontroller). It should also be on a board no bigger than 2"x2".
I've spent the last few hours doing research but haven't yet formed a complete picture of what I need to do. I was hoping somebody would be able to point me in the direction of some more resources or give me a general idea of what my circuit should look like.
I believe I can build the circuit on something like this (maybe a bigger one if necessary): https://www.sparkfun.com/products/8808
I would need a microcontroller like this to controller the buzzer and flashing LEDs: https://www.sparkfun.com/products/10803
In order to program said microcontroller, I would need to make a serial cable like this: https://www.youtube.com/watch?v=XGrf1hegdbU
And the LEDs and buzzer should be easy to pick up from somewhere like RadioShack.
I guess what I'm looking for is how to tie it all together. What type of power source would I need? The microcontroller wants 4.5-5V, but would that be enough to power multiple LEDs? How do I wire everything together? What types of resistors would I need, and where would they go?
Thank you very much for your help,
Mark
