 # flipperzero-geigercounter
 A geiger counter application for the Flipper Zero
+
+<img src="https://github.com/nmrr/flipperzero-geigercounter/blob/main/img/logo.jpg" width=30% height=30%>
+
+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
