hi! does anyone know how to make this? or at least the block diagram? we have this for our project & i don't know where/how to start? pls? really need help
there was a thread about wending machines not so long ago. use the 'search' facility to try and find it. It went into quite a lot of depth, including the use of inductors (I think) to find out which coin had been inserted.
edit: this was what I was talking about https://www.electro-tech-online.com/threads/ic-question.7046/
