Schema


Code

// Program to demonstrate the MD_Parola library
//
// Display the time in one zone and other information scrolling through in
// another zone.
// - Time is shown in a user defined fixed width font
// - Scrolling text uses the default font
// - Temperature display uses user defined characters
// - Optional use of DS1307 module for time and DHT11 sensor for temp and humidity
// - DS1307 library (MD_DS1307) found at https://github.com/MajicDesigns/DS1307
// - DHT11 library (DHT11_lib) found at https://github.com/mathworks/thingspeak-arduino
//
// NOTE: MD_MAX72xx library must be installed and configured for the LED
// matrix type being used. Refer documentation included in the MD_MAX72xx
// library or see this link:
// https://majicdesigns.github.io/MD_MAX72XX/page_hardware.html

  14. When I load the sketch for the first time via USB it works, then when I turn the board off and on again I have to press the Reset button several times to run the clock. If you do not, do not turn on the watch.

  19. Try commenting the following lines;
    //NewStateOfbuttonA = digitalRead(4);
    //NewStateOfbuttonB = digitalRead(7);
    //NewStateOfbuttonC = digitalRead(8);
    Seems to be something related to switch button input pin bouncing.

    2. Mentioned above.
      change P.setZone(0, 4, 1) to P.setZone(0, 0, 0);

      Also, there is no need for the 10K resistors used for so sort of 0 logic on 3,4,5 pins.
      I have removed them(since PULLUP resistors are activated and is monitored only the change of the pin status)and I put the push buttons to the ground.

  25. I will not use a power bank unless that power bank is able to supply 5V while it is hooked at a wall charger and I haven't found one doing that till now.
    What I will use are: the below module + one 18650 battery + a phone wall charger.
    These 3 items are working as an 5V UPS.

    Good luck.

    1. The green module from that link. ”3.7V to 9V 2A”
      Micro USB input, output set to 5V and the battery (at least one ofc :)) to the Bat+ and Bat-.
      This module is dual - it supply 5V while charging the battery and when the input is lost it continues to supply 5V until the battery is depleted.

  26. Dear author (or anyone else),
    Pls adv about how to change the code in order to make, in Mode 1, the scroll not to be shown until we press one of the other push buttons, but to break after the temperature is displayed and revert to the clock. The break the loop in the end I mean.
    I tried, but I am not so skilled.
    Thank you.

  27. Everything is working like a charm following the tuto2and some comments but the clock is running a bit faster.. After some days I have to correct the minutes because is 3,4 minute forward..
    Any chance to fix that?

    1. Did you connect all the Grounds? Review your connections and perhaps replace your RTC.
