Arduino Washer and Dryer Programming

Hi All,

I am a newbie when it comes to Arduino. I would to like to know if there was anyone in this forum that tried to use Arduino and emulate a coin drop in a commercial washer and dryer. I am trying to create a POS application that can control the ON/OFF signal of a washer through 1 terminal. The C# side programming of the POS was well taken care of. The only problem was how can I emulate a coin drop and what code should the Arduino must receive to perform the coin drop emulation.

Please note that I've recently purchased Arduino Nano for this particular project.

I hope someone can help me here as I am in a roadblock for days now. Thanks in advance!

The coin drop mechanism is the hard bit - you need to research what you can buy for that task and what form it’s electrical output takes.

Think about what you do when someone puts a coin in and nothing happens too ...

Are you going to buy a coin acceptor?
Couple I have looked at use a series of pulses to communicate which coins they processed.

Suppose the real question is what did whoever made your C code, program it too expect on terminal #1 in order to run.

Hi All,

Thanks for your prompt replies. Actually,I don't want to operate automated washer using coin acceptor. What I want is for my POS application to send message to the washer using arduino to turn it ON/OFF. I know that for me to be able to send codes to Arduino I must use Serial Port communication in C#. My problem was what code should I send to Arduino for the washer to turn ON, thus emulating a coin drop. A commercial washer have the 8 pin connector to supply power to coin reader as shown on the attached image.
