Okay, I'm an experienced software developer so programming the Arduino has been a breeze.
However, I'm a complete noob when it comes to hardware/electronics, so that's what I need help with.
My first project uses Lilypad. I've worked through the tutorials, and can get each demo working fine. However, I'm not sure how to put it all together correctly. Attached is an image describing what I'm trying to do -- combine on one board a AAA battery power supply, a serial group of four LEDs, two separate light sensors, and two groups of two tri-color LEDs.
Here's a list of current questions which I'm having a hard time figuring out.
- when trying to make a serial connection of two tri-color LEDs, do you connect each LEDs RGB outlet directly to the pin? Or do you connect one light directly to another light, and then have the last light talk directly to the pin?
- when connecting a battery, are there some guidelines around when to wire something (like a sensor) directly to the battery? Or should you only wire the battery to the PWR/GND in the board and have all the power go through the board?
Thanks in advance.
