# Mightyohm.com Geigercounter connected to ESP8266
Here's some code and schematic to connect your mightyohm.com geiger counter to the Internet of Things (IoT).

**If you use the external 3,3 volts, you have to remove the batteries from the geiger counter!**

## compile

The firmware can be built and flashed using the Arduino IDE.
For this, you will need to add ESP8266 support to it by [using the Boards Manager](https://github.com/esp8266/Arduino#installing-with-boards-manager).
Furthermore, you will also need to install the following libraries using the Library Manager:
* ArduinoJSON 6.10.1
* PubSubClient 2.8.0
* WiFiManager 0.15.0

## settings
2020-09-26 17:34:24 +02:00
Since this project is using the WifiManager library, the ESP8266 will open up a WiFi Access Point for its initial configuration
or if it is unable to connect to the previously configured WiFi.
The library pretends that said WiFi AP requires a captive portal which triggers a notification on recent android phones.
Simply connect to the AP with your phone, tap the "Login required"-notification and you should be able to configure everything.
## usage
Since we're using the Home Assistant Autodiscovery feature, everything should just work™.
