Pigpio – A Python module to interface with the GPIO. I decided a thermal imaging camera would be a good tool to have and decided to build my own. ANAVI Light pHAT is an expansion board best suited for Raspberry Pi Zero (W/WH) boards, but also working with any other Raspberry Pi boards with a 40-pin header, that can control a 12V RGB LED strip and sensors. It won't be high-performance, but it looks like a great tool for testing, or for when you just need to switch on an LED or something else simple. Over the years the header has expanded from 26 pins to 40 pins while maintaining the original pinout. Expansion Header. I have a small Python class that simplifies working with the PWM sysfs interface, but it's only a convenience and definitely not required to work with the timers. For a simple test, you can use the command line interface provided by pigpio, named pigs: $ pigs w 25 1 # turn pin 25 on $ pigs w 25 0 # turn pin 25 off Enter GPIO Zero. But it can also send a signal to another device. I bought a FLIR Lepton 3. Passionate about something niche?
