All the students have different tasks assigned. Each one is getting to know, testing and documenting how their sensor works, wiring it up and running a functional test, each on their own setup. We are now at the stage where we are
starting to put sensors together on a single Arduino and merge the code. We are going step by step because I have to teach everyone how Arduino works, although it is true that they already have last year’s experience.
Meanwhile, I have a student who is learning to design PCBs. We have it almost finished and the next step will be to send it for production and wait for it to arrive. It is going slowly too, because they had to understand how Arduino works, how to make PCBs, wait for the others to decide which ports they will connect their sensors to, and also learn to make jumpers because some share RX and TX ports.
And that’s where we are… there is a sensor we have had some difficulty with and we had to edit the library to change memory allocation values, and this has also upset our progress plans a little. We now only have to solve our problem from last year, which was related to the power supply.
Our idea is that once we have all this done, we will add a LoRa module to get the data out. For now everything is being done with the SD card module, where they have also had to learn not just to put data in a file, but in the right format so that we can later open it as a spreadsheet and review the data more comfortably.
