+# flipperzero-geigercounter
+A geiger counter application for the Flipper Zero
+
+![banner](https://github.com/nmrr/flipperzero-geigercounter/blob/main/img/logo.jpg)
+
+You need a **geiger counter** board to run this application. This board can be used : https://aliexpress.com/item/1005004074447209.html
+
+The geiger counter board can be powered with +5V power pin of the **Flipper Zero** 
+
+Output pin for measure on arduino cannot be used on the **Flipper Zero** because output voltage is too low. You can use jack out port instead. This port must be connected on **A7** GPIO :

+
+## Build the program
+
+Assuming the toolchain is already installed, copy **flipper_geiger** directory to **applications_user**
+
+Plug your **Flipper Zero** and build the geiger counter :
+```
+./fbt launch_app APPSRC=applications_user/flipper_geiger
+```
+
+The program will automatically be launched after compilation
+

+
+**A4** GPIO can be connected on **A7** GPIO to test this application without using a geiger tube. **A4** GPIO is generating a signal whose frequency changes every second.
+
+Press Ok button to clear the graph, press back button to quit
+
+If you don't want to build this application, just simply copy **flipper_geiger.fap** on your **Flipper Zero**
+
+## Use cases
+
+Ambient radioactivity :
