📌 Code Examples – 8-Bit LED Indicator Module (Common Anode / Common Cathode Versions)

📋 Overview

This 8-bit LED indicator module comes in two wiring types:

✅ Common Cathode (CC)

  • All LED cathodes are tied to GND

  • LEDs light when the MCU pin outputs HIGH

  • This is the most common and intuitive version

✅ Common Anode (CA)

  • All LED anodes are tied to VCC

  • LEDs light when the MCU pin outputs LOW

  • This version behaves inverted compared to normal LED logic

Because of this, your wiring and code depend on the selected version.

This section provides examples for both versions.

🔌 Wiring (Both Versions)

Pins on the module:

  • VCC — 3.3 V or 5 V (depending on microcontroller)

  • GND

  • D0–D7 — LED segment inputs

Key difference:

Version VCC Connects To GND Connects To D0–D7 Active State
Common Cathode VCC of MCU GND of MCU HIGH = LED ON
Common Anode VCC of MCU GND of MCU LOW = LED ON

🔥 This is where most beginners get confused — in CA modules, the logic is inverted.

🧪 Arduino Example – Common Cathode (CC)

LED ON when digitalWrite(HIGH).

const int leds[8] = {2, 3, 4, 5, 6, 7, 8, 9};

void setup() {
for (int i = 0; i < 8; i++) {
pinMode(leds[i], OUTPUT);
digitalWrite(leds[i], LOW); // All OFF
}
}

void loop() {
for (int i = 0; i < 8; i++) {
digitalWrite(leds[i], HIGH); // CC version lights LED
delay(120);
digitalWrite(leds[i], LOW);
}
}

🧪 Arduino Example – Common Anode (CA)

LED ON when digitalWrite(LOW).

const int leds[8] = {2, 3, 4, 5, 6, 7, 8, 9};

void setup() {
for (int i = 0; i < 8; i++) {
pinMode(leds[i], OUTPUT);
digitalWrite(leds[i], HIGH); // All OFF (inverted)
}
}

void loop() {
for (int i = 0; i < 8; i++) {
digitalWrite(leds[i], LOW); // CA version lights LED
delay(120);
digitalWrite(leds[i], HIGH);
}
}

📊 Binary Counter Example (Supports Both Versions)

Add a single macro to choose whether HIGH = ON or LOW = ON.

#define COMMON_ANODE false // set to true if your module is CA

const int leds[8] = {2, 3, 4, 5, 6, 7, 8, 9};

inline void setLED(int pin, bool on) {
if (COMMON_ANODE) {
digitalWrite(pin, on ? LOW : HIGH);
} else {
digitalWrite(pin, on ? HIGH : LOW);
}
}

void setup() {
for (int i = 0; i < 8; i++) pinMode(leds[i], OUTPUT);
}

void loop() {
for (int value = 0; value < 256; value++) {
for (int bit = 0; bit < 8; bit++) {
setLED(leds[bit], (value >> bit) & 1);
}
delay(200);
}
}

This makes the module universal — works with either version depending on the macro.

🔧 ESP32 Example (CA/CC Aware)

#define CA false // true = Common Anode, false = Common Cathode

const int leds[8] = {16, 17, 18, 19, 21, 22, 23, 25};

void setLED(int pin, bool on) {
digitalWrite(pin, CA ? !on : on);
}

void setup() {
for (int i = 0; i < 8; i++) {
pinMode(leds[i], OUTPUT);
setLED(leds[i], false);
}
}

void loop() {
for (int i = 0; i < 8; i++) {
setLED(leds[i], true);
delay(150);
setLED(leds[i], false);
}
}

🧠 Notes & Tips

✔ Always check whether your module is CA or CC before wiring.
✔ If LEDs all appear ON or all OFF, it’s almost always a CA/CC mismatch.
✔ For Raspberry Pi (3.3 V logic), both versions work but CA/CC inversion still applies.
✔ These boards are great for:

  • Binary counters

  • Debug indicators

  • Sensor threshold states

  • Mode/status display

  • Teaching logic & bit operations
