I have a MCP9700 and it's really simple to get data out of it. Ground, +5V and connect the middle pin to an analog pin on the arduino. From there the simple sketch will display some values: float temp = analogRead(0)*5/1024.0; temp = temp - 0.5; temp = temp / 0.01; Serial.println(temp); Ho…

The proper way to integrate the MCP9700 temp sensor into an arduino

Hello,
I'm trying to understand the *5/1024 portion of the equation. Can anyone explain please?

Thanks in advance.
