If it moves, it will be related with seeeduino code. 2. You can follow http://wiki.seeedstudio.com/Shield_Bot_V1.2/#getting-started to burn the cod...

Re: ITFFF

Hi Marie,

You can run the code on a PC with internet connection. The code reads the humidity base on the API and then use the if function to change the dryer state through API. here is the example which uses the python language. thanks.

The 4 mics pi hat uses SPU0414HR5H-SB mics. The 6 mics pi hat uses MSM321A3729H9CP mics. the mic sensitiv...
