How to read out analog signals (sensors, potentiometers etc) with Raspberry, SPI and MCP3008
The Raspberry Pi has a serial peripheral interface (SPI) which can be used to communicate with microcontrollers, display drivers or in our case digital/analog converters (DACs). By default the Raspberry Pi can’t read analog signals, it only can read digital ones. Depending on the model, there a multiple SPI’s available. In this Tutorial we will … Continue reading How to read out analog signals (sensors, potentiometers etc) with Raspberry, SPI and MCP3008
