you think the buttons from the 8x8 game system would fit on that pcb?

witch of the options that appear on the device family option is the one I need (if I'm using 16F628A)

Thanks

does this transister work for the 8x8 led game system

PN2222A PN2222 Transistor NPN 40 Volts 600 mA

Sorry but what is a pm

Yes i would buy one and i just need the surface mount chips


Thanks Brad

i would pay around 5 to 10. idont know you sold them. if you cant sell me one can you send me like the file or the drawing so i can make one with autocad

hello brad

i know you dont sell the 8x8 led game system circuit board but i was wondering if you could sell me on if so that will be great.

thanks so you fixed the wires that means i have to change them. beacause i connected the 2 gnds and i have the game but backwards. so that means i have to change the wires as you told me.

hello brad i finished the game i did all the steps you told me but when i turn it on only the red dot appears. and if i move it after like 2 or 3 seconds it turns off i think it is because i die but i just cant see the green dots

when we are programing the pic when the pickit2 program says HEX FILE SUCESSFULLY IMPORTED does that mean the pic is programed or do you have to do another thing

really it looks good the vcc and ground from the decoder and microcontroller are good i dont have to add anything

Thanks Brad

hey i made this schematic to make it easier for me to read is it good, does it need more, or is some parts wrong. if one thing is wrong can you please tell me so i can fix it and learn more

Thanks
Brad

in the schematic the 7442 ground is in the 12th pin but in the pic you showed us the its on the 8th pin are they both right or is the schematic wrong.

hello brad for the 10k and 100 ohm resistors what do you recommend 1/4 watt or 1/2 watt?
