Question 17 of 23intermediate🔍 AnalyzeShort Answer2 marks

Did your automation system work as per the plan? If not, what are the reasons? What will you change next time?

Correct Answer

If the automation system did not work as planned, possible reasons include:

  1. Loose connections on the breadboard or incorrect wiring.
  2. Incorrect pin assignments in the programme code.
  3. Sensor not calibrated properly or threshold values set incorrectly.
  4. LED or other components connected with wrong polarity.
  5. Insufficient power supply or voltage issues.
  6. Errors in the programme logic or syntax.

For next time, improvements would include double-checking all connections before powering on and testing each component individually before integration. Additionally, using the serial monitor to debug sensor readings and verifying the programme logic step by step are essential.

Explanation

The chapter emphasizes testing circuits and troubleshooting. Common issues include loose connections, incorrect wiring, and programming errors. Students should document what went wrong and how they fixed it, as this helps develop problem-solving skills in electronics and programming.

Solution Steps

  1. Identify loose connections on the breadboard or incorrect wiring.

  2. Check for incorrect pin assignments in the programme code.

  3. Verify sensor calibration and threshold values.

  4. Ensure LED or components are not connected with wrong polarity.

  5. Check for insufficient power supply or voltage issues.

  6. Look for errors in programme logic or syntax.

  7. Plan improvements: double-check connections, test components individually, use serial monitor, and verify logic.
