I started a Score Board project for my Bike Polo club with my friend Lucas... ( intro )
It's written in python (really beginner with that language)
I use 7 segments leds stripes for the timer/countdown and score for each team
this is working quite good
I control the time limit, start/pause the timer, score, reset... with a pannel with some buttons (switches and push buttons) and also have a monitoring LCD screen (16x2)
The problem I have is when I push a button ( lets say start/pause ) it works, but, at some times some other methods are called.
It can add goals for a team, change the time limit or whatever.
Sometimes it works all perfectly...
I dont have any resitors for the buttons and read today about pull up/down resistors and do not really undeerstand if it can solve my strange behaviors and also what kind and where do I have to put it...
what do you think? o
Here is the code : https://github.com/clemsy/poloboard/blo ... loboard.py
I dont have a schema for the scoreboard but some photos
the left team score is not working because of the shit register is ko
that is also a strange thing, we have like 10 shift register dead.. why ? how ?
