| | |
| Name | SpaceState ESP Clock |
| Initiator | zeno4ever |
| Status | 60% |
| Skills | Basic Electronics, Arduino Software (C) |
| Summary | Show space open/close state with nodeMCU / ESP-12E / ESP8266 |
I wanted to see if the TkkrLab hackerspace is open on my clock. For this I used an nodeMCU with a RGB led to request the spaceapi every 10 mins and display open (green) or closed (red) status. The nodeMCU is a developer board with an ESP8266 / ESP12-E chip. There are a few different types of nodemcu's, check out this article for more information about these
Resources
Parts List
- Clock
- nodeMCU v2
- diffuse 10 mm RGB LED
- 1x 1K resistor (you can alter this depending how brite the LED should be)
Software
- source code for nodeMCU : https://github.com/zeno4ever/spacestatus_ESP
- Library for json processing https://bblanchon.github.io/ArduinoJson/
- Arduino IDE for uploading source to nodeMCU
Steps
I used male breadboard connectors to connect everything to the nodeMCU, you can solder the RGB led directly on the wire (with one resistor on the anode (+))
The clock I have has a 6v that is connected to the Vin and GND of the nodeMCU
- Check the clock you want to use if there is enough space inside to put nodeMCU inside and where to place the LED.
- Check if you can use the power of the clock and this is good for Vin. In my case i had 6 V, this in within the range of 4.5V ~ 9V. If you have a other version of nodeMCU check the documentation.
- Download the source and change the settings for your hackerspace.
- Upload code to nodeMCU via USB
- Connect the RGB LED and power in the the nodeMCU
LED remarks
If you order a LED chip check what type you buy, you have commen anode and commen cathode types. These have to be connected different I uses an common anode. I include setting you can change. I have no tested this part so there may more changes needed to make this work.
I also use one resistor since i only show one color all times. If you want to use more then one color at a time then you should use a resistor per color, so 3 for R,G,B.
You can cut a part of the LED as long you dont touch the parts where the electroncs are. For me I 'decapped' the LED with a iron saw and sanding it down to have a flat surface.
