Research 

I was asked to go off and research on the microbit interfacing with different IOT platforms using MQTT block in microsoft makecode and also look for a platform that had lovely aesthetically pleasing digital I/O and analog I/O dashboard that kids will love, supports visual display (camera feed), gps features (maps) and free or low cost pricing.  . 

Discoveries

Blynk

Pros

  • Microbit mqtt connection using makecode mqtt blocks
  • Digital I/O and analog I/O widgets
  • Visual display (Camera feed)
  • Informative dashboard
  • Gps features (Maps)
  • Affordable pricing
Cons
  • Not backwards compatible
  • Mqtt connection issues
  • No low cost pricing

Pros

  • Microbit mqtt connection using makecode mqtt blocks
  • Digital I/O and analog I/O widgets
  • Visual display (Camera feed)
  • Informative dashboard
  • Gps features (Maps)
Con
  • Difficulty in account creation
  • No low cost pricing
Datacake

Pros

  • Digital I/O and analog I/O widgets
  • Informative dashboard
  • Gps features (Maps)
  • Low cost pricing 
Cons
  • No microbit mqtt connection using makecode mqtt blocks
  • No visual display (Camera feed)

 At the moment i am still on the quest to find an IOT platform that can make an mqtt connection to the microbit using the mqtt block in makecode, digital I/O and analog I/O widgets, visual display, informative dashboard, gps features and low cost pricing.

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 ...
