PA Designer: Try It Out

2. Iterate

If your robot does not recognise a bell when rung, we call this a False Negative.

Repeat the bell ringing test a number of times. Does your robot always recognise the bell and light its LED? If not, how do you think you can improve your robot’s performance?

Make necessary adjustments and re-run this test until the robot successfully recognises 3 bell rings in a row.
