About Sensor-Based Home Security ATmega 8535, On this occasion sya I'll explain about tools, entitled "Sensor-Based Home Security ATmega 8535".
On my device consists of:
IC 324 <1buah>
320 ohm resistor (6 pieces>
Trimpot 150 k <1buah>
Infrared <2buah>
Photo diode <2buah>
Buzer <2buah>
Led <2buah>
atmega 8535
The following rangkaian'a path ..
As for how the instrument, if the infrared sensor on the pass by obstacles or in other words there are barriers that block the infrared sensor to the photo diode in this case buzer will sound.
