[QUOTE="Lightning303, post: 1131532, member: 97876"] Doesnt matter if the ATmega is in DIP or in SMD form. Just make sure that the USB connection is not done with an FTDI or CH340 chip but with an extra ATmega. How many leds do you have/want to use? With 2A you will only be able to power 33 leds. If you use multiple supplies (1 for pi and 1 for leds), make sure to connect the grounds to get the same ground level on the arduino and the leds. [/QUOTE]
