Combining our voice recorder with a motion sensor you can easily construct a talking alarm system that will announce any motion by a sound of your liking.
- Set your power supply to 5V. Using our breadboard power supply (pictured below) you can simply use the 5V output headers (there are two of them).
- Using female to female jumper leads, make the following connections:
- + on the motion sensor to 5V on the power supply
- - on the motion sensor to GND on the power supply
- VCC on the recorder module to 5V on the power supply
- GND on the recorder module to GND on the power supply
- SIGNAL on the motion sensor to P-E on the voice recorder
- Plug the speaker into the voice recorder module.
- Double check all connections (especially the power connections!) and ensure that your power supply is set to 5V.
- Power up!
- Hold the REC button down while making a sound (or playing a sound from your mobile phone)
- Moving around in front of the motion sensor will cause the voice recorder module to playback the last recorded sound.
Note that the motion sensor has a 10s reactivation delay each time motion is detected. This means it will only return to "inactive" again after 10 seconds have passed - only then new motion can be detected.
