PD7 LED flickering

Just got my 3pi today and it’s all that I expected. Great design!

Just one thing I can’t explain. Whether I’m running the demo program, the line follower, or the maze solver, the PD7 LED is constantly flickering!!! It don’t think this is normal… the PD1 LED doesn’t. Any explanation and solution to this problem would be appreciated.


I am happy to hear that you like the 3pi. PD7 is also on the LCD, so if you’re doing stuff with the LCD, the LED will flicker.
