[Pool Water Monitoring] #11 Architecture Design #2: Arduino MKR 1300 WAN receiver and Grove Display

Hi all !

Happy New Year 2022.

Starting with the project designs, working with both Arduinos, one will collect and send information, and the other one will receive and display it.

The following blog entry explains the project design

Data receiving

Part of the challenge is to use the kit - not all the components - at least not my project, but some.

To be able to use the Grove kit (straightforward), an Arduino UNO is necessary.

That part is taken care of, but, if the UNO is connected to the Grove kit, and the MKR 1300 WAN is receiving the data via LoRa, how will we send the data from one to the other?

Serial communication.

Hardware

  • 1x Arduino MKR 1300 WAN
  • 1x Arduino UNO
  • 1x Grove Base
  • 1x Grove  LCD RGB Backlight
  • 1x Grove LED

Here's the schematic

I've placed them all in a 3D Printed support that I've designed (for a Raspberry PI, but still).

Here's some pictures of the support with both Arduinos and LCD.

And here it is.

Next week, let's start coding. The main challenge will be the sharing of data between both - i'm expecting.

Stay safe everyone.
