Reply to |Build Log| - DIY midi gamepad controller

hello all,
(first of all, sorry for my bad english... i'm from portugal)

i've started my controller project.





will be based on:

2 gamepads
1 sound board
30 arcade buttons
2 sliders
8 knobs
1 line in
1 line out

the box is an old plumber tool box that i've found in a Lisbon flea market



since this project will have to be as low cost as possible, i've spend some time searching for the correct design (to prevent mistakes) and also good but not expensive components

at this point i've encontered the first problem...

keeping in mind that the only experience in electronics that i have is to turn on and off the power button of my pc...

said that, please be patience, and please sorry for some of my stupid questions...

so the problem are the LED...

i've managed to connect the analog potentiometer to the PCB and to a LED, it works fine...




but when i connect the button the LED light is not bright...



here you can see what is appening

what am i doing wrong?

thanking you in advanced
