What you learned from the LED switch project
- [Instructor] This is a really simple project, just a switch, an LED, and some software, but you've learned some really important things about the Raspberry Pi GPIO. First, you learned the mechanics of connecting circuits to the Raspberry Pi. Jumper wires and breadboards make experiments easy to set up and change. Hardware on the Raspberry Pi does nothing without software to control it. We'll learn more about writing software in future chapters. Third, you learned there is a difference between input and output. In this project, we used a simple input device, a push button, and a simple output device, an LED. In future chapters we'll look at more complex input and output connections to the GPIO. Finally, you've developed confidence that you can use the Raspberry Pi to explore electronics and the internet of things. I've heard many people say they would like to experiment with a Raspberry Pi, but just never got…
