* A police's siren circuit

* Soldering the electronics components
  

* Finished, not quite.

* Lack 2 pieces of ceramic capacitor 103. 

* Connecting the circuit, speaker and the battery holder.

* The circuit doesn't work, lacking the ceramic capacitors.

* Infrared sensor (transmitter and receiver).

* Connecting the infrared sensor to power supplies.

* Working, indicated by the green light on the receiver.
  

* Since the sound is not working, change to an LED.

* LED lights up if something cross over between the two sensors.
