Task
Prepare the task by studying how an optocoupler works.
Also keep in mind that you must create the protocol that will be used for communication between the two devices Arduino and Raspberry.
Tip!
Study in detail how asynchronous serial communication works. Error handling with parity check or checksum is also part of this.
This technology can be a solution to the task.
The goal of the task is to create a working serial communication solution containing optocouplers between an Arduino and a Raspberry Pi.
Basic requirements for your solution:
Arduino must send a minimum of at least 10 characters via the optocoupler to Raspberry.
Raspberry will receive these characters and print them on console / monitor.
Optional -> (Error handling should be implemented to ensure correct communication. This can be done with parity bit or checksum.)
You get to choose in which way you want to implement your solution and how you want to connect the different platforms to each other with the optocoupler.
Also keep in mind that there are a number of different techniques to solve this problem.
In the report, you will also discuss the following issues.
What technology have we chosen for implementation?
How effective is your solution? Is there any other technology that would make our solution more effective?
Try increasing the communication speed to see what your maximum communication speed can be.
Well-commented program code that you have created during the implementation of this laboratory should be included as an appendix in your laboratory report together with the flow chart.
