+#TWEET YOUR VALUES
+
+This folder contains the code necessary to tweet your sensor values once a minute.
+
+It requires python-twitter library which you can get by
+
+**sudo pip install python-twitter**
+
+Sensors used in this code are:
+* light sensor on port A1
+* sound sensor on port A0
+* temperature and humidity sensor on port D2
+* LED for visual feedback on port D3 (with PWM)
