Summary
In this chapter, an Arduino scrolling marquee prototype was built:
- A discussion on LCD and OLED basics was presented
- An LCD controller is a dedicated microprocessor or microcontroller that operates the crystal segments of the optoelectronic device
- An OLED operates like a general purpose diode and LED
- The only difference between general purpose diodes and LEDs, and OLEDs, is the use of organic materials for the anode and cathode terminals to allow light to be emitted from the device when wired correctly to a DC power supply
- This organic material makes OLEDs more efficient in power consumption and visually appealing than the traditional LCDs
Two scrolling marquee projects were discussed in this chapter. An automatic scrolling marquee was presented where a series of count values (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) move across the OLED LCD at two starting locations (0, 1) and (16, 1). These two starting locations provide an esthetically pleasing look on the OLED LCD. The IR-controlled scrolling...
