This project looks like a great opportunity to design a PCB with the LEDs mounted in appropriate positions to match the spacing of the dominoes.
What is the budget and time frame for finishing the project?
I have finished building the physical part of the project already, just the code left to get it working.
Its just a personal job to go in my own living room, however my wife is fed up with how long its taken so far, hence the call out for help on here, i probably could get my head around writing the code myself....but shes not willing to wait that long!
I've no idea how much I should expect to pay for the code, but i am happy to do so.
