Project translated automatically. Log in or register, to view the original Materials: Arduino, Water flow sensor based on a hall sensor (YF-S201), KY40 Encoder, LCD 2004 screen I2C bus (1602 as an option) Recording readings in EEPROM memory (so that readings and settings are not reset when power is turned off). Functions: On the main screen, in different lines, show the readings of the amount of water used and the remaining readings. When the tap is opened, the flow sensor is activated, and information about the flow (liters per minute) appears on the screen in the first line, and information about the remaining amount appears in the second line. When the set reserve is reached, the remaining readings should flash. You can display a scale and readings in % on the bottom line for clarity. When the encoder button is pressed, a menu is called up, where the following items will be: the ability to add an arbitrary volume of water to the main one (for example, to top up the main tank with a canister of 20 liters of water, or a bottle of 5 liters, etc.), refilling the tank by 100% (the full capacity is immediately entered), the ability to set the minimum water level in the tank (reserve), when reached, the remaining readings should flash, tank capacity in liters, the ability to calibrate the water sensor (for example, open the tap and pass 1 liter of water through the sensor to determine the number of pulses per liter) Backlight, minutes. Settings can be divided into two groups, i.e. permanent (tank capacity, calibration, backlight) and operational correction (additional volume and 100% replenishment). To turn on the backlight, you need to either activate the water sensor (open the tap) or press (rotate) the encoder. After 2 minutes of inactivity, exit the menu to the main screen without saving data.

Budget: 2000 UAH Deadline: 9 days

I can complete your task.
I will work on a regular Arduino Nano, the screen will be 1602.

When completed:
I will demonstrate the code on a breadboard (if I buy an encoder) and send you the code if the result suits you,

You need to upload and test the code (if any corrections are needed, we will make them)

The deadline is indicated with a margin.

Good day. I can offer implementation on Raspberry Pi Pico (RP2040). Or, as an option, on ESP32, which in principle, if necessary, will be able to send data over WiFi.
There is already quite a lot of experience working with these controllers.
