Serial communication continued

This week the project leader Jason asked me to keep working on getting the serial connection between roborealm and the microbit to work.

Problem encountered two weeks ago
Wasnt able to establish the connection using the tera term editor.

Steps involved to fix the problem above 
  • Searched google on how to change the usb port communication number on windows
  • Closed the roborealm application 
  • Opened the control panel
  • Clicked the on the usb port icon
  • Changed the baud rate number to match that in robobrealm (115200).
  • Reopened the roborealm app
  • Ran the serial communication application
  • Opened the serial communication window 
  • Serial communication window showing the word connected in the console section of the window (proof  that the connection was established).

After the connection was established i sent values from roborealm to the microbit and from the microbit back to roborealm.

Steps involved in sending values to the microbit.
  • Typed values in the console section of the serial communication window 
  • Clicked on send now 
  • Values showed in the space below and the microbit blinked as proofs that the value had been sent to the microbit.

Steps involved in sending values to roborealm from the microbit
  • Opened makecode on a browser window 
  • Took the redirect to usb block from the serial extension and placed it in the on start block (meaning redirecting the serial input and output to use the usb connection on start).
  • Took the key A pressed block from the input extension, duplicated it and changed the key pressed to B on the duplicate.
  • Took the serial write number block (which sends a value serially in this case to the roborealm application), duplicated it and placed it in the key A and B pressed blocks.
  • Changed the values in the serial write number blocks to 0 for A and 1 for B
  • Took the show number block from the basic extension (which in this case shows the number that is being transmitted to roborealm on the LED), duplicated it and placed it in the key A and B pressed blocks under the serial write number blocks.
  • Changed the values in the show number blocks to 0 for A and 1 for B.
  • Downloaded the code onto the microbit.
  • Tested the code by pressing A on the microbit (which showed 0 in the console section of the serial communication window in roborealm and 0 on the LED) and B  (which showed 1 in the console section of the serial communication window in roborealm and 1 on the LED).

Next step
Showing the value that is being transmitted to the microbit from roborealm on the LED of the microbit

BYE FOR NOW!!! UNTIL NEXT WEEK

How to: Tello drone to micro bit - Victor Alikberov, Blog#1

Image
1. Introduction. The purpose of this blog is to explain everything that is needed in order to connect tello drone to micro bit. It will cover wiring,  javascript code behind custom created tello extension and how to use this extension to connect and drive tello via microbit. 2. Wiring. Since tello drone creates its own wi-fi hotspot, additional wi-fi module is required in order to establish wireless connection between micro bit and tello. ESP8266 will be used to connect micro bit to tello wi-fi hotspot and also to establsih UDP communications between micro bit and drone. The pinout of the ESP8266 chip is shown below. ESP8266 chip pinout. Receiving port (Rx) is connected to transmitting port of the micro bit (pin 2) and transmitting port (Tx) of the ESP8266 is connected to receiving port of the micro bit (pin 1).  3.3 volts power supply should be provided both to micro bit and ESP8266 chip. Chip enable port is also connected to 3.3v power supply.  ESP8266 plus microbi...

First USV Test - Jack Pender, Blog #5

Image
Introduction: On the 18 th of March we held our first field test at Killurin Bridge in Wexford. We met there at 10 am, with a plan of finishing up at 2 pm, giving us plenty of time to test each aspect of the project we have been working on. It was great to see the USV on the water for the first time, and it helped to visualise it in the setting that its use is intended for. Testing: The main tests for this first field test were to trial the driving functionality; Manual Drive, Microbit Drive and Cloud Drive. Using the controller, the drive of the USV was successful and it was great to finally see its speed and mobility on the water. With the Manual Drive, controlled by Patryck, going according to plan, this allowed us to test the Microbit Drive, which would be controlled by Adam. Using two Microbits to control the direction and thruster power, Adam completed a successful drive of the USV. This was great to see as it meant that the control of the USV could be friendly to everyone...

OpenCV To RoboRealm - Jack Pender, Blog #7

Image
Introduction: Developing further on getting the camera feed from the Tello drone to a viewable format, it was decided to try and get the camera feed into RoboRealm. Once the camera feed is in RoboRealm, it can essentially be sent to anywhere from there, in our case Ubidots, but if this were to change we would now have a better starting point. RoboRealm: RoboRealm was created in 2006 to take advantage of lower cost generic computing, a widening range of lower cost imaging devices, an increasing need and usage of vision as a primary sensor device and the desire to come to a solution with an interactive user interface with minimal programming. This made it ideal for this project as it meant that for future iterations it would be quick and simple for someone else to get up and running with. Procedure: Using multiple of the built-in features of RoboRealm I created a programe that would start a screen capture in order to have RoboRealm capture the drone feed. Firstly, within an if ...
