Lightcomposer Software ReadMe

For all I use Arduino IDE version 1.8.19
General: Validation of FTDI Programmer and Software
Connect FTDI Programmer to Computer and install Blink Sketch. Use USB0 connection (if applicable) and Arduino Uno as board.
Make sure all libraries are added and Arduino AVR is at version 1.6.21.
The Neopixel pin is 9, the number of used LEDs on the board is 32.

1. Validating the available software
The current (30/04/2026) software file is called: LightComposer_Basic_v0.9

2. Firmware Programmer
I use an Arduino Uno.
Burning a boot loader requires me to use the example sktech "Arduino as ISP". In the tools section I have to set the programmer to "Arduino as ISP" (the previous programmer was AVRISP MK II). Upload the sketch to the Arduino. Don't change old style wiring.

3. Burning the bootloader
Now select Arduino Uno board in Tools -> Boards. Press burn boot loader and let it burn. 

4. Uploading a sketch
Select the sketch (LightComposer_Basic_v0.9) and upload it to the MC by selection Arduino Uno in the board settings and do not upload through the standard upload button but through Sketch -> Upload Using Programmer. Wait for it to finish and the software should be running on Lightcomposer. 

Should you run into any errors, double check your wiring, this caused the most issues for me.
