WATER LEVEL INDICATOR USING ARDUINO
download what, copy the code. rightclick save mage
only supply voltage and test resistor values if they work
It will cause electrolysis and the + will disintegrate. (done it) i have this idea to periodically scan sensors for change in level. like after 10 20 sec
always give full details when asking question, and images of your setup, there can be a million thing wrong.
how can we download this???? - shibil
make water level controller using ultrasonic sensorhttps://mrmodder.com/how-to-make-water-level-controller-arduino-project/ - SardarK2
I didn't get any output . I didn't use any Register . Is it mandatory to use Register ..

What changes to the schematic needs to be made if i have a 3.3 V micro controller and a 55 gallon tank?
interface keypad with arduino
I have followed the steps but I am getting only Water level "HIGH". There is no water level showing Average or Low.Please help me to solve.

Hi, I think the values for the resistors R1, R2 and R3 are specified too low. They should be at least 220Kohm. I used 470Kohm since the water 'resistance' is about 1-2Mohm. Also omit unspecified resistor in the 5V line that goes into water. caomitted.omit the
Hi, I think the values for the resistors R1, R2 and R3 are specified too low. They should be at least 220Kohm. I used 470Kohm since the water 'resistance' is about 1-2Mohm. Also omit unspecified resistor in the 5V line that goes into water. Resistors R4, R5 and R6 will adjust the collector current, so choose higher than 470ohm if you want less than 10mA, like 1Kokm ->5mA. Logic levels with this circuit are 'high' for no water contact and 'low' for water contact. I used a 2SC945 standard bipolar NPN transistor and it works reliably. Good luck.
additional comment. You can add a 1 kilo-ohm resistor in series with the 5V 'common' wire to protect the transistor against damage from accidently touching the wire ends directly.
I implemented this circuit but all three pins are showing HIGH LEVEL .. not average , not low level.. plz help me.
the code should be:Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );......................char keys = keypad.getKey();then compile success
This guy have cheated. Its our project. He have stolen from us. The block diagram was designed by me. I have all the primary documents. He just helped us in coding. But now, he have posted as if it is his own idea.
