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!
Some time ago an opportunity knocked on my door. A friend needs a device that would read a card, send the id to the server and react to response.
Today we will work on code and create a class and a handler for the RC522 module.
Module and handler added to NodeMCU boilerplate @ GitHub
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.
We have a touch driver in our GfxLCD package so we can upgrade Doton a little. We will add clickable widgets.
Our window managers will handle touch propagation. For the first widget with action, we will create a light switcher.
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.

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.
