Session 1 · DESIGN: Improve
Electro-mechanical output
- 10 minDemo: a servo turns to an exact angle; a motor spins. Which suits a flag, a gate or a fan?
- 30 minAdd a movement output: a servo that raises a flag, opens a model gate, or points to the trap that fired.
- 10 minUpdate your system diagram with the mechanism and its power supply.
Session 2 · DESIGN: Give Value
Reliability trials
- 10 minPlan: run 20 trials. Count true alerts, missed alerts and false alarms.
- 30 minRun the trials and fill in the test log. Change one thing (trigger level, switch design, wiring) and run 20 more.
- 10 minCompare the two logs. Is it reliable enough for your user to trust?
Getting started
Use the servo starter program and one trigger only.
Stretch
Make the output smarter: a pause so it does not flicker, or a count of how many times it has triggered.
Checkpoint
A prototype with a moving or visible output and a test log showing reliability before and after a change.
Activities for this week
- Servo flag or gate: How do you turn a digital decision into movement?
- Reliability trials: Would your user trust your system?
