Driving an 8-segment display for memes
I acquired these parts from work (otherwise headed into the trash). Due to some memery amongst colleagues, this ensued:
I honestly don't expect anyone to use this project I'm simply showcasing my work here.
This was for some random piece of crap hardware, which the pin layout/wiring may differ for YOUR n-segment displays
8-segment displays are simple devices though so maybe this may actually work for you. Simply remap the pins to your wiring in the code.
I used a coin battery to figure out which pins do what.
I put some resistors on pins 12,9,8 (block select) to current limit. I started with 330Ω but it was too dim, and reduced it all the way down to 39Ω.
It could probably run without a resistor, as the power output from the arduino is quite limited, some ESR in the LCDs, etc. The choice of 39Ω had no criteria. I got lazy and didnt want to re-solder resistors too many times, but still wanted some protection, and simply settled on that.
I had to time-multiplex the blocks and messed with timings and duration to get a good balance of brightness and operability.
No. (actually yes)
IYKYK.
I do not support nor condone for any form of disrespect, insensitivity nor acts of hate. This work was done in good fun and no one was negatively affected directly nor indirectly as a result of this work Use this work responsibly.
no. but it worked so yes
