In this episode of The Learning Circuit, we add an LCD to an earlier Arduino project. We also look at how to do state change detection and reading the position of a potentiometer.

  • Nice, but one observation - the method of counting button presses to change the display between Celsius and Fahrenheit could be prone to being triggered a lot of times as the switch bounces when it’s pressed, but I think you get away with it because it’s only checked once per cycle through the loop, and that’s relatively slow. Might be worth a mention, and a discussion in future perhaps?
