Hope it's ok to bring this thread back- thought it's best to keep everything in one place rather than starting a new thread.
I've recieved my LEDs and Power Supply and am trying to follow John's instructions of plugging it all together- already burnt out one TLC5940 so thought I'd be better off posting here!
My power supply is Regulated 5V 2000mA. I've used the following image to set everything up on breadboard:
To do the following:
>> Regulated 5V supply at 2A or more: Connect + to the Arduino "+5V" pin. Connect + to the TLC "Vcc" pin. Connect + to the anode of each LED. Connect - to Arduino "GND" and TLC "GND".
I've tried leaving everything plugged in as it is and adding the Power Supply's "+" to the "+" line on the breadboard and Power Supply's "-" to the breadboard's "-" line- When I do this nothing works?
I've also tried replacing on the breadboard the wires from Arduino's "+5V" and "GND" and plugging my Power Supply's "+" and "-" into the holes the Arduino's wires were in. Also doesn't work.
Should I plug the Power Supply's "+" directly into the Arduino's Board's +5V Pin? That doesn't seem to make sense as then the power wont be getting to the breadboard?
Just tried plugging the Power Supply's "+" into the Arduino's Vin Pin and the power supplies "-" into the Breadboard's "-" line. This works but I'm aiming to run 16 120mA LEDs fora total of 1920mA- and I've read the Arduino wont let more than 1000mA through it?
Sorry to ask for help for such a simple question I just don't want to mess any more chips up!
