In Part I and Part II of this series, we learned how to use an analog sensor — including a potentiometer (POT), a light-dependent resistor (LDR), and a soil-moisture sensor — to present values on an organic light-emitting diode (OLED) display.  In Part III, we’ll also present data on an OLED display, but this time…

In Part I of this tutorial, we learned how to present data (or values) using a potentiometer (POT) and an organic light-emitting diode (OLED) display. For this project, the POT was an analog sensor (potentiometers can also be digital), which acts as a resistor to control the flow of an electric current. The OLED technology…
