Hello,
i used this code to read analog value(lithium battery max 3.7 volts) from arduino mega analog pin 0, but i always get 5 volts, i changed the pin to analog 8 (pin 63) and changed battery connection, it reads OK, I would like to know how to declare analog pins 0 to 7 and how to differentiate them from digital pins 0 ~ 7
Thanks

private Sub UpdateBatteryInfo
Dim USBsense, BatteryOut As Pin
Dim RawVolts As UInt
Dim BatVolts As Double
Dim isUSB As Boolean
Dim isConnected As String
USBsense.Initialize(0,USBsense.MODE_INPUT)
BatteryOut.Initialize(1,BatteryOut.MODE_INPUT)' if i change pin to 63,it works ok
isUSB = USBsense.DigitalRead
RawVolts = BatteryOut.AnalogRead
BatVolts = RawVolts * (5.0 / 1023.0)
If isUSB Then
isConnected = "Pluged"
Else
isConnected = "XXX"
End If
