Rainbowduino - problems with programming

[Miles]

@jensstark

Thanks!

I now did the following:

• follow link, unpack
• open Rainbow_CMD_V2_0 with Arduino 0017
• compile (resulting sketch size 5688 bytes)
• connect SparkFun AVR Pocket Programmer to Rainbowduino → PWR LED is green.)
• avrdude -c usbtiny -p m168 -U flash:w:Rainbow_CMD_V2_0.cpp.hex
• lights flash, verfy is OK.
• disconnect programmer
• attach external power supply, pwr LED green
• press RESET, reset LED red.
• remove power
• add LCD matrix (square pin in round hole).
• reattach power supply → pwr LED green.

Still nothing happens…

I’ll probably do something wrong along the way

Best,
Jens

Confirm your matrix is actually working. Can you hook up a simple power > resister > matrix > gnd circuit. That way you can rule out the matrix being faulty
