A minimal 'Arduino UNO' board for starter costs less than US$5 and can be purchased thru many online stores. Getting Started with Arduino UNO Step 0: Buy an Arduino BoardĪrduino Board comes in many flavors. It is intended for artists,ĭesigners, hobbyists, and anyone interested in creating interactive Strip.begin() // This initializes the NeoPixel library.'Arduino is an open-source electronics prototyping platform based onįlexible, easy-to-use hardware and software.

This is some code that started life as the AdaFruit demo, but I changed it so that it is implemented as a state machine so you can change the pattern any time you like, even part way through a cycle. It might be something with the libraries but I have only used the AdaFruit one and I have seen the code to cope with a Mega in that.

I have attached the pictures of my temporary setup (due to breaking my soldering Iron & only having a 180 ohm resistor rather then a 100ohm.)Īny help with the code or making the rainbow effect would be great! tPixel(x + y*ledsPerStrip, rainbowColors) Int index = (color + x + y*phaseShift/2) % 180

Thanks for the reply, I think there is an issue with the Mega 2560 as I switched to my spare Teensey 3.1 & now have the LED's reacting to codes uploaded to it.
