here is what i tried, note i don't use c++ often (blue moon level rareness but the main idea is you need a switch statement) i added a suffix of '//++'.to lines changed by me so you can see what im trying. note: i assumed the pulses sent is in increments of 1000, if this is wrong you will need to change each case to the correct pulse count expected for that note as well as the 'min_cost_of_service' and 'max_cost_of_service' (min_cost_of_service = pulse count for £5 and max_cost_of_service = £50) #include <Keyboard.h> /* This program expects pulses of logic high coming from a bill acceptor into pin 0 on an arduino leonardo.

This one is for Chris, truly the saddest time we have had to face as a community. R.I.P Chris and again thanks for all you did for us.

Only just heard the news truly devastating, MFME like most of us has been apart of my daily routine for years and has brought me many thousands of hours of joy re living my younger days. thanks for everything you did Chris. R.I.P

ive been dragging my feet with the release as the base art used was bad to say the least and so the layout is not good. i might upload later today if i get time to prepare the layout for release.

if your using the g540
