Ch-926 coin acceptor identify coins

[@ch40skappa64]

Thanks:) with a bit of effort i got it working. Searched for days thank god i found this video:D PS: the way you detect the pulse is smart af;)

[@craynerd]

Cheers mate!

[@CarstenMeyer]

Very elegant code to differenciate between the coins. Thumbs up.

[@mattdgroves]

I'm trying to connect this coin acceptor to a USB Controller board (like for joysticks). Any idea what voltage the pulse is? I believe the USB controller is expecting 5V? Or do you have any idea how I would set this coin pulse up to map to a USB button or even a keyboard key?

[@KuyaMagik]

do you still have the code

[@craynerd]

I’ll have a look in a few days when I’m back home. I should somewhere!

I have grounded arduino and coin acceptor in one ground. using white whire in 2or 3rd pins but getting pulse even when i touch the coin validator case with metal coin or knock on a validator with a coin. shoul i use NO or NC? Thanks in advance

[@craynerd]

Did you get this sorted?? I had a very similar issue but grounding everything as you described sorted this!

[@GiorgiGvimradze1]

yes i lately found out that i havent grounded it :) but Ive lost about 1 week to get it by myself

[@craynerd]

Giorgi Gvimradze lol I'm sorry my delayed reply and having you sort it out for yourself lost you a week. In future I will ensure I am immediate in my reply.

[@essedisystem430]

Hello, can anyone tell me which kind of signal the coin selector give? Furthermore the out signal is 5V? Thanks. Regards.

Please comment the whole code you used. We want the full sketch of this project. Thanks.

Grey wire is a coin counter ground output...

[@tjdals3035]

i have troble about power, Arduino continues to receive high and low digital signals continuously

[@italaa86]

Hello i need something which is almost what you did, it's for car wash machine, by connecting that coin acceptor to a raspberry pi and increase time counter according the impulse number given from it and display it on screen lcd, once time finish i should stop motor, i hope you help me to know how i can receive impulses by raspberry and read them ??? thanks a lot

[@martinchavez2596]

Hello I am interested in reading the pulses to detect if I enter a coin, I use a NRI G13 validator of 6 channels. Each channel sends a pulse, but I receive false pulses, can your code work for me?

[@thabisoedwintjatjie5339]

The is helping i'll try to write my own codes, but please don't forget to help me with the codes.

do you have the programming video for the accept-or

[@yalfenymartinez1450]

greeting brother very good video you could send me the code or where could I get it thanks and discula my English is not my native language

[@juleshell5801]

The grey wire is for a counter - connect this wire to one side of counter and other side of counter to +

Hi, in what way, to look for what?

[@MrGakure]

But for sure help me on this,,,,because i have the same model,i went through the setting and sampling procedure very well but once done and complete, the coins are not getting through but get returned to the return slot,what is the cause ........... Very good Stuff.Thanks.

Hi! i'm having a problem with the output value. it sometimes differ even when I insert the same value of coin simultaneously. do you have an idea about this?

[@craynerd]

John Bon have you got a common ground between all components - arduino AND coin hopper?

[@johnjovibon7504]

yes. both ground of psu of coin slot and ground of Arduino. we don't have yet coin hopper. do you have a code for arduino? we want to try it.

[@johnjovibon7504]

it's working now! I just added 10k resistor then the value of coin inserted is ok now. Thank you so much for the code!

[@johnjovibon7504]

do you have a code for the coin hopper? we want to put coin changer.

[@craynerd]

John Bon I'm currently on hols in Wales but I'll look when I get home. If I remember correctly, the coin hopper gives an output line with a number of pulses for each coin type. The arduino just sat waiting for impulses, counted the impulses when they came and turned on the coin hopper. Sadly, you couldn't tell the coin hopper how many coins to dispense but instead it pulsed each coin as it was ejected. Again, I just used the arduino to count the number of coins coming out of the hopper and shut it off.

[@yusrijamaludin]

I got a problem where pulse voltage from acceptor is about 20mV. And sometimes, it trigger a pulse but no coin inserted. Maybe I know what is the pulse voltage. How can I solve my problem?

[@craynerd]

+Yusri Jamaludin Have you used a common ground? I had a similar issue but it was solved when I grounded everything together.

[@yusrijamaludin]

+craynerd I have grounded the coin acceptor to arduino GND and power source 12V-GND. The unwanted pulse is disappear but still exist 1, 2 pulse after I left the circuit unattended for 5 to 10 minutes. May I know what is your ground circuitry?

[@craynerd]

Sorry, not too sure with that one and my ground was simply tying all of them together as you have already explained. Can you detect a random pulse that is causing the hopper to fire or more specifically the Arduino to detect it? Is the coin acceptor attached to anything that could be interfering or causing a potential difference? Sorry, I`m guessing here! Please post back if you do figure it out and help others
