Oh don't mind those

Just look at the circuit those were notes

It s a discontinued counter ic

I didn't use shift registers becaus I wanted to get at least 60 reads on every button and Every board, or playing would be akward

You can scale forever if it's a less intensive application, say a keyboard

@Ondsinet grounding bypass and/or decoupling caps
ground to IC gnd pins or arduino gnd plane?
shortest path wins, or save the 4 hot IC gnd pinds from any extra stress?

Connect to ic pins

And they should all be connected together anyway

It really wont matter in this case

Also stress<:covfefe:440543908846632980>

of course theyre all connected 😄

thank you

still no solder wick yet

<:pepe_why:378719408367075333>

The 4 grounds on that ic are there to allow it to sink more current

And the datasheet says for heat dissipation so I guess you are supposed to leave a good blotch of solder to act as a makeshift dissipator

A capacitor there won't cause any kind of stress

it says it wants some copper down there, or a grounded heatsink. mine's not getting that hot but im gonna up the voltage, and then later im gonna stack these bitches for the hell of it

Found a photo of my l283d ic setup

did you had to make your own breadboard?

Did you had

I just like to have things nice and clean

Compare to your jumper jungle lol

fuck if i noticed, my whole room looks like that

in all seriousness i have used some extra wires to make some connections more accessible to pull out later

theres a lotta ways to make a pasta

That board has connectiona for:
2 motors
4 enstops
1 rgb led
2 buttons
1 RFID board

And they all neatly plug in

Btw we're gonna have tanks, boats and drones

<:pepe_smug:378719408341909506>

need tank shipping boat

/helicarrier

is that paint pen on the headers?

Sharpie

And gnd

well that shows up nicely for a sharpie

Needd to give instructions to unskilled workers that would have to assemble it later

(me from 2 days later)
