#87889 Gooday! I may ask to everyone, if it is possible to reject a coin from a Universal Coin Acceptor using a esp8266? for example , i need to push first a button before a coinslot accept a coin? can i see a sample code.

here is my code;

void ICACHE_RAM_ATTR CoinAccept(){
StartTime=millis (); //start of time every coin drop

void setup() {
attachInterrupt(D5, CoinAccept, RISING);
