Summary

In this chapter, we learned what a super-bright LED is and how we can connect it to a microcontroller board. We also reviewed how to use the super-bright LED as a powerful visual alarm, since it glows much more intensely than conventional LEDs. We also summarized what Morse code is, how it is used worldwide, and how to show the SOS Morse code message, which is used in visual alarms as a distress message, by turning on and off the super-bright LED connected to the Blue Pill and Curiosity Nano microcontroller boards. Connecting a super-bright LED is not straightforward, since we will need to know how much current it will draw, because the microcontroller boards' output ports can handle a very limited amount of current, in the order of a few milliamps. This chapter will be beneficial for readers who would like to control an LED in other electronic projects. It also points out the importance of carefully calculating the amps that are drawn by a super-bright LED and using the...
