You will not be able to read the code as it is sent as binary data, as long as you get a response that is sufficient for now. The Arduino will send a status code for the state of certain pins and then stop.

The Arduino should send a series of letter A's to the serial monitor, enter some text in the text box and click Send. Download the code to the Arduino and then start the Serial Monitor. Choose SerialCallResponse from the Examples -> Communication menu. We can first test serial communications with some example code included with the Arduino. If the LED is already flashing then you could change the values of the two delay statements and ensure that the speed of the flash of the LED changes appropriately. The blink code will flash the onbord LED which is connected to I/O port 13. You should also select the appropriate Serial Port - which is normally /dev/ttyACM0 (if you are unsure then run dmesg after plugging in the Arduino). First you should select the appropriate model of Arduino from Tools -> Board. Clicking the right arrow button the menubar will compile the code and send it to a serial device. You can test that the Raspberry Pi is able to program the Arduino by sending a sample program, such as Blink from the included examples. The IDE can now be found on the application menu under programming and electronics.

First install the Arduino IDE by issuing the following command from the terminal. We will start by setting up the Raspberry Pi to allow us to use it to program the Arduino. Programming the Arduino from a Raspberry Pi If you are using a different manufacturer then you may need to choose a suitable controller or add your own to the Arduino IDE. This should work with any Arduino / Genuino microcontroller boards (which is recommended).

In this example I will be using an Arduino Mega 2560 (which provides 56 digital I/O ports and 16 analog input ports). In addition the programming of the Arduino will be performed using the Raspberry Pi so there will be no need for an additional computer. This will allow the two to work together in an electronic project. This will explain how the Raspberry Pi and Arduino can communicate together using serial communications over the USB port. This uses the same techniques shown in the previous video, but is a different example of how you can achieve this. This is a guide that I created prior to the above video. Getting started with Raspberry Pi and Arduino communications

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. These are generally asynchronous communications sent half-duplex with one side sending at a time. This example uses the USB port which uses UART serial communications. Another useful thing is to use the Arduino to provide additional connectivity if you run out of GPIO ports. The Arduino does not have the overhead of running a full operating system so is particularly good at realtime communications, whereas the Raspberry Pi has the advantage of a full operating system and network connectivity. The Raspberry Pi and Arduino can compliment each other.

Ive used you script and also played around with multiple variations of my own ex:ДЄny input would we much appreciated.Currently using python 3.5.Raspberry Pi and Arduino Serial Communications over USB I even tried using a USB to serial adapter and changed my port settings correctly. encode('utf-8') with no luck.ДЄlso i have verified that i have correctly configured uart setting made from the CL. x= ser.write(b'hello') I've also tried encoding my ser.write. i can only write with a byterarry function ex. I have verified my port settings on both my script setup and terminal emulator to make sure they match. The problem I'm having is when I'm transmitting ser.write (or ser.readline) data to a terminal emulator it translates to unreadable characters on the terminal emulator(garbage data).
