BC337 not working - darlington???

[DanPBP]

Hi Guys,

The circuit as I posted works fine with more than 5 volts on the base of the transistor, fully bright LEDs.

Yesterday, I did a new PCB with the BC337 placed between cathodes and ground and now they work just fine with the PIC.

Thanks for your help! Btw, I'm a software guy, sometimes electronics beats me.

Daniel.

Hi Guys,

I owe you a pic and a video of the final product, a "neon light" for my street R/C car...

I made two of them, one for each side... Maybe I will make one for the front and one for the back with less LEDs...



The software is not finished yet, just a test to see how it works... The idea is to generate different patterns according to the throttle/break signal given to the servos...



Regards!

Danie.
