We are using the header file of the LCD, which eases our interfacing the LCD with Arduino, and the pins A0, A1, A2, A3 are allotted for data transfer between LCD and Arduino. The sensor's output pin ...

There is a calibration value at the top of the code called calibrationFactor. This needs adjusting to compensate for your meter. This is all run on a Wemos Mini with a soldering board backpack. Get ...

Circuit diagram of the water flow meter is shown in Fig. 1. 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 ...

For powering the ESP32-S3 we have used the ADP1706 ultra low noise LDO, and for the reset circuitry we have used the ADM803 power supervisory chip. We have also included a provision for a 1.28” round ...
