MQTT is a standardized messaging protocol designed for machine-to-machine communication. It is commonly used by smart sensors, wearables, and other IoT devices that operate on networks with limited bandwidth. Due to its lightweight design and ease of implementation, MQTT efficiently transmits data between IoT devices. It enables communication both from devices to the cloud and from the cloud back to the devices.

For this lab we were tasked to setup an IoT MQTT panel using an app of that same name, to send and receive messages from our Micro:Bits.


 

 


 First I setup a 'debug' panel which displayed the raw JSON payload, allowing me to verify the format was correct and that it was receiving all of the micro:bits. I could then setup gauges to corresponding micro:bits using the JSON payload to view their rotation. I then added a slider which moved from 0 - 255 which i could then use to send a number to one of the micro:bits depending on what jsonpath I stated. I also added a HRV Trend graph which would show what inputs were being sent to the micro:bit.

 


 

 I really enjoyed this lab, it was really interesting watching the micro:bits communicate wirelessly with each other. I would also love to explore the possibility to wirelessly stream video with a camera and the micro:bit.

For my idea I want to explore integrating MQTT with IFTTT. My idea is to configure my micro:bit to send an email notification whenever the micro:bit is rotated. This would demonstrate a real world application of IoT automation, where device movement triggers an action, such as an alert or message.

 Week 3 -

For my IFTTT project, I built a functional compass using a micro:bit and a Cloud Board. The goal was to trigger an email notification whenever the micro:bit points north, this was all powered by IFTTT and webhooks. This project showcases how hardware and cloud automation can work together seamlessly, making it a very interesting way to explore IoT concepts.

Future additions to this project would be the ability to also see the bearing displayed on the LED screen.

Iteration 2 | Jack | HRV Micro:bit Research

Iteration #2 - Micro: Bit Research & HRV Jack Duggan | 20094010 | IOT Apps For the second iteration sprint of the module, I got hands-on with the Micro:bit. I had previously used these devices way back in secondary school for Leaving Certificate Computer Science, so the basics came back to me fairly quickly. We were sent home to 'research' the Micro:bit, and become familiar with it's basic functionality, before class on Friday the 2nd of February. In the class, I worked alone (as we had an odd number of students present) with a Micro:bit V2, an expansion board for the Microbit, and a heart rate sensor. Above is the physical setup Below is the device output screen with my finger on the sensor. The top graph shows my pulse as analogue input as identified by the sensor. Some mathematics is performed (as shown under the below graph) that converts these pulse values to HRV (delta_t). This HRV value is then displayed on the 'boxier looking' graph underneath. The way t...

Iteration 5.2 | Lock In | Jack

Iteration 5.2 | The Lock-In 🔒 Jack Duggan | 20094010 | 10/05/2024 The "lock-in" was something initially devised months ago, an idea that involved taking a couple of days towards the end of the semester to commit fully to this module. As the semester began to wind up in terms of general workload, it became increasingly apparent that this "lock-in" would be necessary. In week 10/11 when we finally set it in stone, it was a great relief off all of all shoulders, knowing it was one less module to stress about, especially with already rampant workload due in week 12/13. With the lock-in pencilled in for the second week of May, it allowed myself and the others to put increased focus on other modules, and helped reduce the stresses we faced at this time. Eventually, the lock-in week did come around, and I and the others arrived in the room on Tuesday 7th May at 10am sharp. We had split into two teams, one team consisting of Emma, Conor and Eric that would look at adding H...

Week 1: HRV Review

Image
  What is it? Heart rate variability (HRV) is the measure of the variation between heartbeats. It is controlled by your autonomic nervous system (ANS). This system operates automatically and regulate process such as the heart rate and other bodily functions that are are not under conscious control. This system is broken into two branches the flight or fight (which preparing the body for action and stress) and the rest + digest (which promotes relaxation + recovery). HRV is influenced by the ability to smoothly shift between these two branches.  High HRV: Larger difference between successive heartbeats - Indicates a more flexible and adaptable autonomic nervous system.  Low HRV: Smaller differences between successive heartbeats - Indicates a less flexible autonomic nervous system.                                                ...
