So the pimoroni pan tilt hat has three headers on the bottom - 2 for the servos and one for an LED light strip. Instead of a light strip i want to use a small laser diode. The diode runs at 5v but i can’t figure out how to turn it on-off. I tried setting the light_mode to 0 (for PWM control) and then using set_all(0,0,0,0) but nothing seems to work.
I suppose I could hook up the diode to one of the GPIO pins on the pi but I can’t really access them with the hat in place. Suggestions?
