 ** The Demo **
 
-This test blinks the onboard LED and also writes/reads to a 24C64 connected
-to the I2C pins (PD0/PD1 on the ATmega1280). There's no feedback provided but
-the I2C can easily be analyzed with any logic analyzer or sniffing with a
-buspirate or similar device.
+This test blinks the onboard LED and also prints the result of the ADC
+conversion to the Serial0. A voltmeter can be use to compare the printed
+value to the value on pin A0 of the arduino board. To make this test, a
+potentiometer is connected to the pin A0 of the board.
