Hi all, I need some help/guidance/confirmation that the idea I've got is about right.. I have 5 sets of christmas LED lights, which have their own wall wart power supply, and their own 'function box' for the flashing etc. I don't like that they never do the same flashing effect, so I want to replace every one of the function boxes with a single Arduino.
I've created a block diagram to illustrate what I would like to do, and would like to know if this is a decent plan of attack.
The reason for using a tip31 transistor is because.. well I have them already.. But if something else will serve better there, then I can purchase them instead.
You'll also notice that there are 2 transistors per LED string, this is because each of them have 2 individual strings twisted together, so this way I'll still be able to access both string separately.
Also, the hardware that I was planning on purchasing off eBay are as follows:
PSU:
**broken link removed**
24V to 12V step down:
**broken link removed**
Thanks heaps
Luke
