Small organic light-emitting diode (OLED) displays are commonly used in embedded devices. This is because OLEDs generally cost the same as character LCDs but feature a better user interface (UI) and user experience (UX). Typically, embedded OLED screens are used to display textual messages, but what about videos? For example, is it possible to playback…
How to display data from an ultrasonic distance-measurement sensor on an OLED
In Part 1 of this series, we learned how to interface an organic light-emitting diode (OLED) display, using analog voltage (a potentiometer), with Arduino. In Part 2, we covered how to present data from an analog sensor — specifically, a light-dependent resistor (LDR) and soil moisture sensor — on an OLED display. In Part 3,…
