📖 Student Help & Experimental Protocol Guide Dr APJ Abdul Kalam Zero-cost Research Lab

Step 1: Phone 1 Sender Connect Phone 1 to the PZT Actuator. Select wave type (EMI Sweep or Tone Burst) and click Run Sender. Saves sender_log.csv with emission timestamp.

Step 2: Phone 2 Receiver Connect Phone 2 to the PZT Sensor at a measured distance. Click Run Receiver to capture structural waves and save receiver_log.csv.

Step 3: PC Convergence Transfer both CSV files to your computer. Upload them into the PC Workbench below to instantly calculate time delta ($\Delta t$) and path distance on screen.

Step 4: Master Merger Click Generate Master Merger Report to download a consolidated CSV audit log combining raw data and complete theoretical calculations for your lab report.
