Weekend Project: COIN COUNTER MACHINE
Status: Prototype

Board: ARDUINO UNO

3rd party LED display For Coinslot insert coin Tap to Ftech Centralized system.

Requirements:
- Fuxion LAB CB V5
- 12v 5A power supply
- TM1637 4-Digit 7-Segment Display Module.
- Arduino Uno
- USB 2.0 Type-A to Type-B (PRINTER USB CABLE)
- Arduino IDE code editor (installed on your PC)

WIRING DIAGRAM

Arduino → LED display

* Pin 3 → CLK
* Pin 4 → DIO
* GND → GND
* 5V → +5V

Arduino → coin slot (FUXION LAB CB)

* VIN → red wire (coin slot)
* Digital pin 2 → white wire (coin slot)
* GND → black wire (coin slot)”

Code:



SIGNAL_PIN 2 // Connect to COIN SIG on Fuxion board
CLK 3
DIO 4

TM1637Display display(CLK, DIO);

int totalAmount = 0;
int pulseCount = 0;
unsigned long lastPulseTime = 0;

void setup() {
// Passive mode: Listening only
pinMode(SIGNAL_PIN, INPUT);

display.setBrightness(0x0f);
display.showNumberDec(0);
}

void loop() {
// Monitor the shared signal line
if (digitalRead(SIGNAL_PIN) == LOW) {
pulseCount++;
lastPulseTime = millis();
while(digitalRead(SIGNAL_PIN) == LOW);
}

// Update display after the coin drop finishes
if (pulseCount > 0 && (millis() - lastPulseTime > 200)) {
totalAmount += pulseCount;
pulseCount = 0;
display.showNumberDec(totalAmount);
}
}

DIY nyo na lang. Paste nyo lang code sa Arduino code editor, youtube nyo na lang pano mag compile ng code, madali lang.
