NodeMCU RC522 and an electronic case

There are a hardware and a software but this is not all, there is also a case that holds all together 😀 and makes project look good 🙂
The Client wants a nice looking case and this is easy to understand. So new area for me, how to make nice holes for connectors, LEDs, switches and so, last time (with NodeONE) it wasn’t all good.
But today there is no room for failure! Let’s get to work!

Daj się poznać / Get noticed – summary

Time is almost over but we have so much more work to do! Of course, we won’t stop our work but let’s summarise was has been done during competition.

The main goal was to build a control node that can gather and display information from different sources/sensors. This node is the Doton project.


But before we could create it we have to do two other projects: a GfxLCD python library, NodeOne sensor and improve one: NodeMCU boilerplate. So, in fact, we have done four projects 🙂

Doton on bigger screen

We have a driver for ILI9486 320×480 display and we can run Doton on it. But currently, it would use only half of the screen. Our window manager has hard-coded dimension 240×320.

We need to do something with it. I think we can update manager to calculate grid from dimensions and additionally we can add tiles auto positioning.

Why? Because it seems that not setting position on the screen can be better 🙂 System can add pages when required and take care of horizontal vs vertical position.
But I think that we should be able to set coords if we want to.

Node One – a multi-purpose node

Today we combine the power of HLK-PM01, PIR HC SR-501, DHT11 and a light detector.
Together they create a nice looking multipurpose Node One. I wanted to do it for some time but the last piece was missing. I didn’t have an idea how to create a box for components.
Few days ago I found a perfect case named Z27. It has all I wanted, socket, plug and enough space for NodeMCU v3.

NodeMCU and light detector – part 4: a module and a handler

We have a nice node that detects light, it works in toilet @ my work 🙂 It does it jobs almost perfectly. There is still a hack for it – leave a light on when leaving the toilet. I have an idea to fix this but first, let’s reforge a lousy code into a module and a handler. After refactor we may safely add it to the NodeMCU boilerplate.

This is going to be our second data node for display.  It will show area lightness and with conjunction with a time, we can tell if an artificial light is on or off.
