Arduino Python Cross platform Data logging to CSV file

• Learn to build a low cost data logging system using Python and Arduino UNO board that will log and save data to a CSV (Comma Separated Values) file on the disk.

• The system will use an Arduino and an analog front end based on LM324 opamp to measure temperature from 4 LM35 temperature sensors.

• The analog values are digitized by the Arduino UNO's (ATmega328P) 10 bit ADC and transmitted to a PC or MAC using Virtual Serial Port communication.

• A Python 3.x.x script running on the PC will receive the data and log the time stamped data into a CSV file on the disk.
