Step 1: ​Materials:

  • Arduino PIR Motion Sensor
  • Buzzer
  • Led

Step 2: Electronic Circuit Diagram:

Step 3: Description

We're all connections and our software, we have completed our yüklüyoruz.alarm system.

Note: Project actively used for buzzer while passive 'HIGH' case, while active 'LOW' What happens in case. You are the exact opposite to be passive buzzer, the software in the 'HIGH' and 'LOW' to change the situation.
