Arduino and Raspberry Pi, working together over a serial communication. Step-by-step tutorial (UART)

The Raspberry Pi and Arduino are both excellent platforms in their own right, but they both have their pros and cons. As I discovered in my earlier video why accept compromise when you can have the best of both:    • Arduino Vs Raspberry Pi - Which shoul...   This video shows you how you can connect a Raspberry Pi to an Arduino, both to program the Arduino and then to communicate with the Arduino. In this case the Raspberry Pi takes on the role of a primary controller with the Arduino acting as a secondary device responding to the instructions of the Raspberry Pi. #raspberrypi #arduino This is achieved using serial communications over USB, although could also be applied to direct serial from the Raspberry Pi GPIO to the Arduino Serial pins (with appropriate voltage level-shifting). This example uses the USB port which uses UART serial communications. These are generally asynchronous communications sent half-duplex with one side sending at a time. This is similar to RS-232 serial communications that you may have used on older computers, but this uses different voltages and doesn't meet the full RS-232 specification. #uart The video explains the circumstances this can be useful, before working step-by-step through a practical exercise with the Arduino measuring an analog input voltage and reporting that to the Raspberry Pi, and the Raspberry Pi telling the Arduino when to turn an LED on and off. The communication between the Raspberry Pi and the Arduino is over a custom text based protocol, making it easy for humans to understand the communication. First the code is created on the Arduino using C++ which can be tested using the Arduino IDC serial monitor. Then the serial code for the Raspberry Pi is added in Python which sends instructions to the Arduino. This is going to form the basis of more advanced projects that I'm hoping to work on in future.
