CIRCUIT DESCRIPTION
Connect the Components according to the given diagram above.
- Connect the Components according to the given diagram above.
- First TRANSISTOR BC547 collector connect with 330-ohm resistor to positive rail on the breadboard
- Emitter connects to the positive terminal of led and negative terminal of led connects to the negative rail on breadboard
- Base wire connects to the water tank
First, connect all the wire and components then connect the battery. Must use plastic glass for this project. |
- Second TRANSISTOR BC547 collector connect with 330-ohm resistor to positive rail on breadboard
- Emitter connects to positive terminal of led and negative terminal of led connects to the negative rail on breadboard
- Base wire connects to the water tank
- Third TRANSISTOR BC547 collector connect with 330 ohm resistor to positive rail on breadboard
- Emitter connects to positive terminal of led and negative terminal of led connects to the negative rail on breadboard
- Base wire connects to the water tank
- Positive wire from the positive rail on the breadboard connects with the water level.
- Attach the buzzer on the breadboard.
- Connect the positive terminal of the buzzer to the collector pin of the fourth transistor and the negative terminal of the buzzer to the GND rail of the breadboard.
- Connect the emitter pin of forth Transistor to the positive rail on the breadboard.
Then connect the battery.
WORKING
When the water level reaches to point A circuit with green led & Transistor Q1 gets completed and green led glows.
Similarly when water level reaches to point B , Circuit with yellow led and transistor Q2 gets completed and yellow led glows.
Same goes with point C and finally when tank gets full at point D circuit with buzzer gets completed and buzzer starts beeping.
