pi_ina219. This Python library supports the INA219 voltage, current and power monitor from Texas Instruments with a Raspberry Pi using the I2C bus. The intent of the library is to make it easy to use the quite complex functionality of this sensor.

pyb_ina219. This library for MicroPython makes it easy to leverage the complex functionality of the Texas Instruments INA219 sensor to measure voltage, current and power.

micropython-fingerprint. MicroPython library for reading Grow and ZhianTec finger print sensors.

battery-monitor. Particle Photon based 12v car battery monitor. Useful for alerting you that the battery is becoming discharged.

water-system. This project uses weather API's to determine if significant rain has fallen in the last day, or is forecast today, and if so disables the garden watering system to conserve water.

air-quality. An air quality sensor and display that uses the BME280 and CCS811 sensors to read temperature, relative humidity, equivalent CO2 (eCO2) and Total Volatile Organic Compound (TVOC) and displays the values on a 2.9in Waveshare e-Paper display.

parametric-openscad-box. OpenSCAD parametric box for electronic projects

micropython-lib. Core Python libraries ported to MicroPython

ds3231-breakout. Low Current RTC Breakout With Super Capacitor Backup

gps-speedo. Small GPS speedometer

daikin-ac-photon. Arduino

esphome-daikin-ac. Enables automation of a Daikin AC in Home Assistant

type-watch. Trains you not to type harshly to prevent OOS

crsf-gps-speed. Sensor which reads from a GPS module and sends telemetry values using the CRSF protocol, which can be consumed by an appropriate ELRS radio control receiver.

type-watch-attiny. Trains you not to type harshly to prevent OOS

key-typer. Arduino program for rapidly typing characters using a Pro Micro as a USB HID keyboard, useful for stress testing text UI input fields.
