In Thursday’s class, we learned to work with analog signals on the Arduino. If digital signals are 0 and 5 volts (logic LOW and HIGH), analog can be anything in between. We can create an analog voltage level from a 5 volt line using a simple two-resistor circuit, called voltage divider . By varying the value of circuit [...]
