    I created the PCB follows your diagram but my trigger flash and camera are swop.

    My trigger flash at pin 12 and camera at pin 10 and 11. I try to change a pin number in the program but It doesn’t work.

    I wrote the easy program to check my PCB board. The Flash can fire.
    this is my code.
    const byte FT1_PIN = 12;
    void setup() {
    // put your setup code here, to run once:
    pinMode(FT1_PIN, OUTPUT);
    digitalWrite(FT1_PIN, LOW);

    void loop() {
    // put your main code here, to run repeatedly:

    digitalWrite(FT1_PIN, HIGH);
    digitalWrite(FT1_PIN, LOW);

    However, I upload and change my flash trigger to be pin number 12 in your code. The flash, not fire. How can I solve it? or I miss something?

    I strongly suspect you have mis-connected things. To be sure I would need to see your PCB design files.

    The pins can be changed, see the start of the sketch:
    const byte CT_SHUTTER_PIN = 12;
    const byte CT_FOCUS_PIN = 11;

    const byte FT1_PIN = 10;
    const byte FT2_PIN = 9;
    const byte FT3_PIN = 8;

    Just change the above to suit what connections you want. Please note; if you upgrade the sketch you would need to change the pins again.

    Thank you for your response. I found my problem. I upload firmware v3 to my board that is version2. Now I downgrade to version2. It’s ok.
    Thank you.

    Glad you found the issue.

    I am now so focused on version 3 I forget to include older versions when trouble shooting.
