I have a kit, Mega + shield LCD 16x2 + DS18B20 temperature sensor, connected to the notebook's USB.
If I use mega and the DS18B20 connected to 5v, the serial works correctly. However, when I put the LCD on, the DS18B20 stops working and always shows "-127"
Could it be that the LCD steals power causing the sensor to not work? Or is it something else?
