Use Logger Pro’s newly enhanced ability to control a Vernier Digital Control Unit (DCU) to challenge your students to create an alarm system that gives a warning when someone enters an area. The ability to turn on or off an electrical device in response to inputs from a digital sensor, an analog sensor, or time, opens up a new world of STEM challenges for your students.
- Connect the buzzer to line 1 of the DCU.
- Connect the DCU (with power supply) to the digital (DIG 1) port of the interface and the Motion Detector to the digital (DIG 2) port.
- Configure Logger Pro.
- Configure the DCU.
- Click to start data collection. When someone passes within 1 meter of the Motion Detector, the buzzer should turn on.
