AVR basics: reading analogue input

It’s an increasingly digital world, but not all information comes packaged neatly in 1s and 0s. Sometimes you have to deal with analogue voltage levels using the microcontroller’s analogue to digital (ADC) converter. Measuring analogue voltages is made easy in Arduino projects because the IDE comes with a handy analogRead() function. Providing your input voltage does not exceed what the… Read more »
