5v Illuminated Arcade Buttons with the Brain Jr.

Hey All,

I have a question about buttons for the Brain Jr. 
Could I use these buttons? I'm sure the button would work, but could the LED as well?: 

"We suggest using red, orange, or yellow LEDs for optimal brightness. These can probably be any color, so long as the LED voltage is less than 5.0V". Yes, but these are exactly 5v. Could this be remedied with resistors between the LED's and the Brain Jr.? I'm new to electronics.

Thanks for your help.



  • Yes those buttons will work, and no resistors are required. The only effect of the higher voltage requirement would be that the LED is slightly dimmer.
