We’ve got tons of projects, libraries and example code for CircuitPython on microcontrollers, and thanks to the flexibility and power of Python, it’s easy to get it working with microcomputers like Raspberry Pi or other ‘Linux with GPIO pins available’ single board computers.
We’ve written a special library called Adafruit Blinka to provide the layer that translates the CircuitPython hardware API to whatever library the Linux board provides.
We’ve added all the libraries to PyPi so installation is super simple via pip. We’ve also updated the CircuitPython guides! They now have sections for wiring up the sensor to and installing the libraries on your Raspberry Pi. The CircuitPython code works exactly the same way it works on microcontrollers, so the code examples will work on your Raspberry Pi too!
We have over 80 guides to update, so watch for updates to the Adafruit Learning System in batches. Here are the next five:
Adafruit HTU21D-F Temperature & Humidity Sensor Breakout Board – this I2C digital humidity sensor is an accurate and intelligent alternative to the much simpler Humidity and Temperature Sensor – SHT15 Breakout It has a typical accuracy of ±2% with an operating range that’s optimized from 5% to 95% RH. Operation outside this range is still possible – just the accuracy might drop a bit. The temperature output has an accuracy of ±1°C from -30~90°C.
Adafruit PT100 RTD Temperature Sensor Amplifier – MAX31865 – in this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0°C, thus the name PT100. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT100’s have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability.
Adafruit NeoPixels – these popular products are chainable from one to the next so you can power and program a long line of NeoPixels together to form an endless (or almost endless) string of 5050 LEDs. Plus, with our NeoPixel Uberguide, wonderfully written NeoPixel library for Arduino and our diverse range of Learn System projects, it’s never been easier to both find a project and program it to glow or spin or flash as quickly, slowly, and vibrantly as you want.
NeoPixels on Raspberry Pi – the popular Adafruit guide on specifically using NeoPixels on Raspberry Pi boards
Adafruit VEML6075 UVA UVB and UV Index Sensor Breakout – this little sensor is a great way to add UVA and UVB light sensing to any microcontroller project. The VEML6075 from Vishay has both true UVA and UVB band light sensors and an I2C-controlled ADC that will take readings and integrate them.
