Arduino with LM35 temperature sensor, data logging using Excel Data Streamer(code & description @ ↓)

The code link and explanation for the project:

Using Excel data streamer to received the temp sensor readings. But data streamer does not log the date and time of the readings. So I use Excel with VBA to provide the date and time for the sensor readings and log it to the Excel sheet.
The interval of the sensor reading is control by the Arduino script.
