CANADUINO PLC (soldered)

It’s alive! Easy-to-program Arduino-style PLC. Goal: practice soldering and basic logic, then blink some relays for a quick shakedown.

📐 Project Photo/Diagram

Notes:

• Very easy to program and modify in the Arduino IDE.
• Screw terminals make wiring quick.
• Soldering this kit is a nice warm-up project.

🧰 Parts List

• CANADUINO/Arduino-compatible PLC kit
• Soldering iron, solder, basic hand tools
• USB cable + Arduino IDE
• Test load (e.g., LEDs) or relays as needed

💡 Test Code (blink through 3 relays)

// Murphy Labs™ | CANADUINO PLC relay test
// Blink-style example for testing the first 3 relays

#define RELAY1 2
#define RELAY2 3
#define RELAY3 4

void setup() {
  pinMode(RELAY1, OUTPUT);
  pinMode(RELAY2, OUTPUT);
  pinMode(RELAY3, OUTPUT);
}

void loop() {
  digitalWrite(RELAY1, HIGH); delay(500);
  digitalWrite(RELAY1, LOW);  delay(500);

  digitalWrite(RELAY2, HIGH); delay(500);
  digitalWrite(RELAY2, LOW);  delay(500);

  digitalWrite(RELAY3, HIGH); delay(500);
  digitalWrite(RELAY3, LOW);  delay(500);
}

🔍 How It Works

The sketch simply toggles output pins connected to on-board relay drivers/relays (check your kit docs for exact pin mapping). It’s the classic blink pattern, just spread across multiple outputs to verify solder joints and outputs.
