Here you can find some my files for Arduino IDE (actually, they should work with any C compiler for AVR [and, mayby, not only avr], not only with Arduino IDE, but I didn't test them anywhere but Arduino IDE)
There are thei short description:
- BH1750.h - BH1750 I2C Light sensor
- BMP180.h - BMP180 I2C Pressure sensor
- DS18B20.h - DS18B20 1-Wire Temperature sensor
- RTC.h - I2C Real Time Clock (Tested with DS3231)
- voltageRead.h - Some functions for helping get voltage fro internal ADC.
