The cash reader is powered by a 12V supply, and “emulates” quarter inputs to the machine by sending multiple signals for each bill. Meaning, a dollar would be output as four quarters, five times that for a five dollar bill, and so on. This functionality is shown at the end of the clip on an Arduino Mega with an LCD keypad shield. The machine also has a 5V input, which can activated by an Arduino to make it flash LEDs and reject all bills when “business is closed.”
