Then there is a bit signifying whether the controller wants to read or write. with the help of the circuit diagram we can complete the wiring and assembly of our project. SPI Wiring (Arduino Uno/Nano) Set DIP switches: SEL0=0, SEL1=1. For the Arduino Nano, SDA is A4 and SCL is A5 — same as Uno. The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Controller board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices. Final Thoughts By completing this project, you’ve learned how to interface a water level sensor with an I2C LCD and Arduino to build a basic water level monitoring system. . Board settings ← these are mandatory, not optional# Board : Arduino Nano# Processor : ATmega328P (Old Bootloader)# 7. So I bought some hardware, consisting of a 1602 LCD Keypad shield module from DFRobot and an anonymous I2C serial module for LCDs. #de los pines del arduino nano conectados al modulo de reles import smbus import time # Dirección I2C del Arduino ARDUINO_ADDRESS = 0x08 bus = smbus.
