Hi Im hoping you can help me update your code to work with my hardware design.

Im using 42 WS2812B Leds per 7 segment digit (6 Leds per digit segment)(Main 4 digits), two far left smaller digits are 17 Leds per digit (3 Leds on segments going across and 2 Leds for segments going down) to show UP or DOWN.

Two buttons (Red for stop and/or pause, Green for start )

The 16X Keypad is to allow me to enter the session time for work/rest and laps (Example: if i enter 10 on the keypad then the display shows 00:10 but if i enter 110 then the display shows 01:10, same for rest time then last part of setup is number of laps)

Can you help me update your code to work like this with my hardware as im a Arduino coding noob :)

Hello Michael,

First of all, that’s a nice project ! :) Sure, I can try to help you with your code !

If you have a bit more info, did you start to create a peace of code that I can check? It will help me to understand and think about how I can adapt my code.

Hi again The project started when i found this crossfit timer project (https://www.youtube.com/watch?v=anBJnOmhjhE) but i didn't like only using two leds per segment and 3 buttons so i changed these stl files to the design in the image above. My though was if i use 6 X WS2812B leds per segment i will get a better spread of light over the segment and if needed i can increase/decrease the brightness. The reason for the keypad was to make entering the work/rest/laps times easier :) well that was the thought!! The original design used a ESP32 as the microcontroller which i started with but after reading up on microcontroller choices for makers and how sometimes a simpler microcontroller give better program stability i changed over to using the Arduino Nano. That choice lead me to find your project :) The main problem ive been facing is i have 172 leds in the first string (34 in the second that controls the two smaller digits on the left) and in the original design they used a binary string to set the leds per digit and i had 42 bits which is to much for a int or a long integer. (https://github.com/PlumPot55/SevenSegment_Dispay). I then found some code that addressed each segment as a block on leds (https://learn.adafruit.com/ninja-timer-giant-7-segment-display/build-the-circuit), i liked the way he coded this but my coding skills are not up to that :) This lead me to using a Arduino Nano, i thought using a 8bit Microcontroller instead of a 32bit ESP32 would make the code a bit easier :) but as my coding skills are not that good and im struggling.

The design is: Main Digits: 42 leds per digit (6 per segment), 2 leds per dot (2 X 2 dots = 4 leds), 172 leds total (Nano pin D3) Sub digits (far left): 17 leds per digit, 34 total (Nano pin D2) to show UP/DN and other program indicators like memory save position like P1/P2/P3/P4 Piezo buzzer = https://thepihut.com/products/large-enclosed-piezo-element-w-wires?variant=27739589457 RTC=DS3231 Keypad=16 key Switch Membrane Matrix KeyPad (Hopefully use A,B,C,D keys to store as retrieve saved session settings like tabata and other custom session types ) Microcontroller=Arduino Nano

I have used the FastLed example CRGBSet_7segment_3digits.ino to prove all leds in each string work :)

Sorry for the long reply but i was trying to give you as much info as possible about my design

sorry forgot to add i want to use your code as i like the using the RTC so the timing is spot on :) i just need to get it to work with my hardware design, then piece by piece get all the functions included :)

Also i got this Fastled example to work with my first two main digits and i like the way it splits the segments into blocks, segA, segB, segC, segD, segE, segF, segG make working with the segments far easier for me :)
