Want to make overhead water tank circuit. But you are not getting CD4066 IC as it is not eaisly available.
Don't worry this project doesn't want any IC OR CAPACITOR.
This project is based on the priciple of real over head water tank circuit.
NOTE: USE ONLY TAP WATER NOT THE DISSTILLED WATER AS IT DOESN'T CONDUCT ELECTRICITY.
All the positive terminal of four leds are connected togethere with positive 9v or 12v source and the negative terminal is fixed on the bottom most surface.
All the negative terminal of led's are connected with wire as per the height required at 1/4th ,1/2nd, 3/4th and lastly at the top most level.
As water is filled in that particular container the level of the water raises in that particular container. The negative charge is conducted in the water.
As level of water raises to the 1/4th level of the container the one of the led that has the wire on 1/4th level gains the negative charge and one led glows up.And as level of water raises and raises up and water touches the wire and the led glows up and finally when the container is completely filled all the led glows up.
So lets make up this simple but awsome project. For this you need the following.
1 9v battery.
4 different colour leds.
and finaly some time.
Step 1: CIRCUIT DIAGRAM
Step 2: SOLDERING THE LED'S ON PCB
Step 3: FIXING THE WIRES ON THE GLASS STRIP
I have used the small glass strip and its length is equal to the length of wire of the longest wire coming out of the negative terminal of one of the led(THIS IS THE WIRE WHICH WILL INDICATE 1/4 LEVEL.) and fixed all the wires on it by using black electrical tape on the glass strip.
NOTE : DON'T TAPE THE STRIPPED PART OF THE WIRE (THE INNER COPPER OR ALUMINIUM WIRE).
If you look at second snap shot(THIS IS OF THE BACK PART) you will see that I have fixed one more wire which is not connected with any thing on the both ends. This wire I have fitted because I will be providing the negative power source through it. The last end at the bottom is slightly longer than the whole length of the glass strip.
Step 4: CONNECTION OF BATTERY HOLDER.
Step 5: FIXING AT RIGHT PLACE
Step 6: RESULT OF THE PROJECT
