I am new to the world of electronics, and I was wondering if any of you guys could help me by looking over a project that I am currently working on. I have all the individual pieces planned out, but I want to make sure I am going about this the most efficient way as possible.
The project is going to involve an Arduino Duemilanove, 20 80mA LEDs, 20 20mA LEDs, and 20 QRB1114 Sensor/Emitters.
There will be 20 individual modules consisting of 1 80mA LED, 1 20mA LED, and 1 QRB1114.
I guess my question is, what is the best way to get all these things power?
Here is a layout that I drew up. Please hold back on the mocking of my drawing. I just downloaded EAGLE for the first time, and I really dont know what Im doing.
Please do not pay attention to the part numbers on the drawing. Like I said, I am new to EAGLE, and I am not sure how to find all the correct parts at the moment.
The 3 open ended lines are going to my going to my LED driver and Arduino.
I thought this would be the best way to keep all the wiring down to a minimum.
Does this look ok? I was planning on running all the vcc and ground lines to a central bus, I guess you would call it.
Are using the transistors a good idea? I thought of using those so I am not trying to power all the lights off 3 16bit LED drivers.
And the last question... How to calculate the power source for such a project? I'm not asking anyone to do it, just wondering what things I should be looking for. I was hoping to have everything running off my 5v Arduino with the source coming from the wall.
Any and all comments are welcome. Thanks in advance for any feedback.
