Description
Descriptions
– Front entry electronic Coin Selector and electronic roll down acceptor with reject lever.
– CPU coin rolling down speed and timing presetting by directional accept sensors.
Invalidate against unusual stay , Reverse Draw, String Skip, Technical Fishing.
1). To change the coin you wish to accept, simply lift up the retaining bracke and insert new sample coin and the mech. will accept only that coin.
2). Accepts coins based on the coins diameter size, thickness and material content.
3). Capable of accepting a wide variety of coins and tokens.
4). Adjustable sensitivity to eliminate acceptance of high quality slugs.
5). Anything that does not match the sample coin is automatically rejected.
Features
1). CPU Anti-string Programs Electronic Coin Equalizer
2). Capable for accepting all worldwide Coins and Tokens.
3). Mechanism—link with coin reject bar , Flush Clean from coin jam.
4). Select coin based on Diameter, Thickness and Metal content.
5). Switch of Normal Open and Normal Close for signal output of coin validation.
6). 3 ways adjustable triggering Pulse Duration of Timer Switch.
7). VR tuning and sensitivity switch of coin acceptance for eliminating slugs and improper coins.
8). Allows to connect Counter Meter.
9). Easy installation.
User Guide
Getting started with the CH-738C Plastic Front Panel input Advanced CPU Coin acceptor for vending machines
In this tutorial we will use the CPU Single Coin Acceptor CH-738C. This Coin Acceptor works by compare the coin that already inserted in this sensor (blue/Red color at sensor) with the coin that inserted at the front hole. If the coin is the same, the coin will accepted, but if coin is different, the coin will be rejected.
Hardware required
- Arduino UNO
- Jumper wires
- CH-738C Plastic Front Panel input Advanced CPU Coin acceptor for vending machines
- Resistor 1ok
Connecting the Hardware
CODE
const int coin = 2;
boolean insert = false;
volatile int pulse = 0;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
attachInterrupt(digitalPinToInterrupt(2), coinInterrupt, RISING);
delay(1000);
}
void loop() {
// put your main code here, to run repeatedly:
if (insert) {
insert = false;
Serial.println(“coin detected!”);
delay(1000);
}
}
//interrupt
void coinInterrupt() {
pulse++ ;
insert = true;
}
RESULTS We will make a sketch that will print Coin Detected when a match coin is inserted.
