Hi guys, I'm using a Pololu motor driver with the VNH2SP30 chip ( Pololu - VNH2SP30 Motor Driver Carrier MD01B ) to control voltage to a thermoelectric cooler and every time the driver comes on and sends current to the thermoelectric device my DS18B20 sensors start putting out incorrect readings. Nota…

Interference from motor driver

The sensors ground to the arduino, which grounds to the power supply.
