Now that you have traveled this far with us, how do you feel? Do you need a break, or more coffee? Before you do either, let's review.

In this project, we got started with the LED blinking example using the Raspberry Pi. We discussed the setup of GPIO peripherals and using them in an experiment. You are welcome to continue experiments with the GPIO peripherals with projects such as LED sequencing, three bit counter, and so on.

In the forthcoming projects, we will look into I2C communication, SPI communication, and UART communication (serial port).
