Anything related to analog-to-digital converters (ADCs). ADCs are hardware devices that convert analog signals to digital signals.

These devices are extensively used to interface digital equipment (such a computer or a microcontroller) with the external world, since they allow, when coupled with suitable transducers and signal-conditioning hardware, to convert any continuous physical quantity to a number representing its value.

See the Wikipedia article on ADCs

Multiple analog to digital converters on Arduino using SPI bit banging

I am using a Nano Arduino (ATMega 328) to communicate to two 12-bit MCP3208 ADC chips based on this code. I have another device (LED driver TLC5940) tied to the pins that are suggested on this page but since I am using bit banging, it should not…
