How do you do Raspberry Pi v.1 lights programming. I want to change lights

 

What tools did you use to write the program you have now? Python perhaps?

 

What lights?
How do you want them to change?
I'm sure there are plenty of code examples already available if you search with Google.

How many lights and at what frequency? I assume lights means LEDs.

For low frequencies with a small number of LEDs, you can use a scripting language like Perl, csh, or Python. For more demanding requirements, a higher level language will be more capable.

If all you want to do is blink LEDs, Arduino can drive single LEDs (or multiple in series) without needing the the outputs to be buffered. Pi outputs are 3.3V and can't sink or source much current.
