This project consists of analogue flow sensor, RFID tag, RFID reader, 16×2 LCD, solenoid, Arduino Uno, a single channel relay and a 12V DC power supply. Fig. 2: Circuit diagram of the liquid vending ...

It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

Arduino Flow Meter Sensor Code: In this project, we are going to build a flow meter sensor and pressure sensor using Arduino and displaying it on a LCD display. Flow sensor has a rotor and a Hall ...

Temperature Monitoring: The DHT11 sensor measures the temperature, and if it falls below a certain threshold, an alarm buzzer is activated. Flow Rate Measurement: Two flow sensors measure the flow ...

I2C protocol makes it easier to connect more ICs using only 2 wires SDA and SCL and allows communication between them at relatively low speed. The I2C bus or TWI (Two Wire Interface) allows a single ...

A 3D-printed flying quadcopter drone. 3D printing and flying drones are among the two most popular activities for Arduino owners.Here we have a project that combines both activities into one ...

The circuit is built around Arduino Uno board (Board1), 16×2 LCD (LCD1), and water flow sensor YF-S201 (SENSOR1). The Arduino is the brain of the circuit that measures the amount of water flowing ...
