Conclusion

This wraps up our look at controlling LEDs with Arduino. Thank you for watching and following along.

In the past few segments, we’ve gone over a lot of different concepts, encoding, and electronics, including but not limited to building a basic LED circuit, using the serial monitor and serial plotter to visualize data with the Arduino, pulse width modulation, how push buttons, potentiometers, photo resistors, and RGB LEDs work from both a hardware and software perspective, how to write C code for Arduino using integers, “for” statements, “if” statements, functions, and arrays, and the advanced concept of Charlieplexing, including the math, circuitry, code, and theory involved with making it work.

That’s quite a lot. These concepts can feel intimidating at first. But now that we’ve gone through everything, you can see that if you take each piece one step at a time, it’s not that scary at all.

Hopefully you can take these examples and apply them to your later projects to further build your knowledge base as you explore electronics and programming in the future.
