Since Raspberry Pi doesn’t have a built-in ADC (Analog to Digital converter) to read the voltage off from most of sensors, the best solution is to add I2C ADC chips and modules to your project. Paweł Spychalski faced this problem while building his own weather station that is based...
Continue ReadingIntroduction to I²C and SPI protocols
byteparadigm.com has a nice introductory article on I2C and SPI protocols: Today, at the low end of the communication protocols, we find I²C (for ‘Inter-Integrated Circuit’, protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well-suited for...
