coin slot machine connection
« on: September 03, 2010, 06:17:28 AM »
mga master need pow sa connection sa coinslot machine...baguhan pa kasi ako, ang out put pala namin ay ekakabit sa dynamo. bawat holoh piso iikot ang dynamo for 4 or 5 sec.
ang mga connection sa coin slot ay "12v, ground, counter, coin" at may mga switches for time ata un
" 60ms, 40ms, 20ms" at "NC at NO"
ask ko lang pow san po ba ekakabit ung counter at coin...gagawa paba ako ng circuit for timer or d na...
at para san ung mga swtiches pow...
thinx sa totolong..yenox pala ung brand sa coin slot machine..

COUNTER pin will be the output of the Coin Acceptor (still i dont know what is the use of the COIN pin :D )

the NC and NO indicates the default setup of your Coin acceptor.. in NC, the Acceptor is closed, if the Coin is validated it will now open else it will rejected.. while in NO, it will close if the Coin if Rejected..=)


about the "60ms, 40ms, 20ms", this is the length/width of the PULSE(output) of the Acceptor... for example.. a 5 peso coin will output 5 pulses.. your acceptor is set to 20ms.. it will output 5 pulses every 20ms.. (you can use Timer0 here if you are going to use an MCU)

No a 5 peso coin or 10 peso coin will output only 1 pulse and 60ms, 40ms and 20ms is the time interval of the pulse. It is 1 pulse/coin and 60ms, 40ms, 20ms is the selection of the pulse width.

Yes kailangan mo ng timer para sa 4 or 5sec control ng motor mo. For this bili ka ng Yenox Timer.

Check mo lang muna kung puede ma set ang Yenox Timer for 4 or 5 seconds kasi ang alam ko minutes ang pinaka shortest time setting tanong mo na lang sa nag bebenta kung puede 4/5 seconds.

oh sorry.. "interval" is the correct term..

and sorry i was pertaining to a Multi Coin Acceptor =)

here's a sample snippet sa pagfetch ng signal sa acceptor, with a 50ms interval per pulse when interface in MCU..

Code: [Select]
if(InsertMoney){
      if(COINACCEPTOR){
         InputAmount++;
         BUZZER = 1;
         delay_ms(50);         
         BUZZER = 0;
      }
      if(BILLACCEPTOR){
      }
}

Connect the output (white wire) to a voltage divider (relative to 12Vdc supply) since 12V ang output nya if naghulog ka ng coin, Then feed the output of the voltage divider to Monostable Timer like LM555 (configured tp 4-5 seconds). Then connect the output of the timer to a transistor which drive the Dynamo.

since 4 to 5 secs lang naman ang kailangan mo puedeng 74121 ons-shot na lang gamitin mo download ka ng datasheet at search mo sa internet ng mga example circuits using 74121.

thinx pow mga master....

master may nahanap na ako na site pero d ko parin naintindihan..pano ko eh set ang time for 3 or 4 sec..kasi 3 trigger input, 2 for low and 1 for high...at sa time interval naman mag base naman sa resistor and capacitor depends sa value..pero mayroon naman time interval sa coin slot.....plsss help pow...

hi! yung akin pong project is that it will just detect the coin if it was accepted, kunwari i have a variable x so sa una x = 0 magloop lang siya hanggang madetect niya yung coin na ma accept then maging x = 1 na that's the time na mag rurun na ung program.

ang ginawa ko po is ung coin signal naka step down voltage po siya to 5v (which is acceptable sa pic) then ung output ng step down kinabit ko sa isang paa ng p16f877a tapos it detects the pulses using PULSIN, i've noticed that if a coin is inserted ung pulse niya nag 200+, now my problem is that,  kahit di na accept ung coin pumapalo parin ung pulse niya sa 200+, basta tumama lang siya sa bakal pumapalo siya sa 200+ eh ang condition ko panaman ay if coinpulse>200 then ... end if....


im using proton ide in coding simple lang naman siya, tingin ko may problema ung coin slot

buhayin ko lang ito, yung isang output po ng coin selector ay open collector npn kasabay ng paggalaw nung solenoid sa coin selector ang output, pwede ng lagyan ng pullup sa 5V tulad ng ginawa ko dun sa auto water machine :D

Usually I hack the circuit by removing the transistor then replacing it with jumper. Yun 5V na ang output
