Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

Water level sensors of the water tank at roof, and water level sensor of the water tank at basement (ground) can be connected to the circuit through sockets J1 and J2 respectively. Socket J4 is the DC ...

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display, and more.

Water Level Sensors, Alexa In A Fish, And Modular Synths During World Create Day. ... The first is an LED matrix that eleven-year-old Daniyal brought to life using Arduino.

I've got an Arduino/Bluetooth (Bluetooth Bee-Standalone). I've hooked it up with an HC-SR04, it's intended to be mounted at the top of a rain barrel to measure the water depth. What's the best ...
