EXPLANITION
Power
supply 240 Volts
·
This circuit needs 12 volts DC of supply
for the operational of the circuit. Enough power is required to generate the
circuit. Alternative current (AC) also can be used instead of direct current
(DC) but AC need to be convert to DC current by using step down transformer,
bridge rectifier, filter and voltage regulator. The power supply of 240 volt AC
is converted to 12 volts DC.
Front
and Back Limit
·
This project use limit switch. This
limit switch function is to stop the cloth hanger when its time.
·
This switch will activate when the cloth
hanger is moving back to the limit switch sensor, this will make the motor to
stop and ready to make the motor to rotate another direction to open/close the
cloth hanger.
Forward
/ Reverse Control
·
This project use the relay to control
the cloth hanger to lean forward or backward.
·
The relay will change the condition of
the rotation when the cloth hanger is step on relay switch at back or front at
the cloth hanger.
Light / Rain Sensor
·
This project use 2 type of sensor:
o
LDR
§ The
LDR is use to detect any change of the light brightness/contras of the
environment.
§ This
will make the cloth hanger to close when there is no light and at night.
o
Water Sensor
§ The
water sensor is use to detect if there is any rain or water.
§ When
there is a water at the sensor, the cloth hanger will close and when the there
is no rain the cloth hanger will open back.
Motor
·
We use 12v DC motor to make the cloth hanger to
move forward or backward.
·
The direction of motor rotation is depends on
relay.
·
The relay will change the positive (+ve) and
negative (-ve) current to the motor.
