I have a charity car project that is ongoing. Our vehicle will be customised with lights, motors and sounds.
I have a standard arduino and a 4-relay board which is working well using various sketches I have found on the net.
I was wondering if anyone could help me with a sketch that will turn on 3, or 4 of these relays at a time interval that I can set from a single N/O momentery switch. I also need it to reset after a certain time so that when the button is pressed again the sequence will start again.
I have an HD44780 LCD that I'd like to work into the design that could display text just before the relevent relay becomes active.
I know this is a big ask but i severely lack the programming knowledge to do this.
I hope someone can help, i'm sure it's not too difficult for you pros!
