+### circuit diagram
+
+**time spend:** 15 min
+
+**what i did:** some simple logic in my brain told me that i need 2 buttons, a display and a chip so i placed them and wired them in the schematic!
+
+**images:** ![my circuit diagram](https://hc-cdn.hel1.your-objectstorage.com/s/v3/5bddc22bf6116f6ae2bc093ed7d6ff0133d386d8_image.png)
+

+
+**time spend:** 25 min
+
+**what i did:** i first tryed to do it all in just the top layer! and i successed, but then i tryed auto rouuter and it did it so mutch better!

+
+### wrote the code for this to work!
+
+**time spend:** 40 min
+
+**what i did:** used 2 simple tempelate codes for using the display and the button then merged them and added some of my own logic cosue i know python! tho i have no idea on how to test it :(
+
+### done

firmware or whatever!
