Do you have too many sensors with the same I2C address? Put them on the SparkFun Qwiic Mux Breakout to get them all talking on the same bus! The Qwiic Mux Breakout... $13.95 In Stock Add to Cart TheAdafruit TCA9548A breakoutis used in this guide. However, the SparkFun breakout has...
Multiple Max6675 Arduino based Industrial Temperature Monitoring System-In this tutorial, you will learn how to make an industrial temperature monitoring system using Arduino, i2c supported Oled display Module, andmultiple Max6675thermocouple temperature sensor amplifiers based on the K type thermocouples cap...
The TCA9548A I2C Multiplexer Module is to enable to connect devices with the same I2C address (up to 8 same address I2C) hooked up to one microcontroller. The multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pin with your command. The multiplexer itself i...
This guide shows how to read temperature from multiple DS18B20 temperature sensors with the ESP32 using Arduino IDE. We’ll show you how to wire the sensors on the same data bus to the ESP32, install the needed libraries, and a sketch example you can use in your own projects. This tutor...
Arduino Wireless Servo Motor Control using the RF24Network Library Before we explain the main example of this tutorial, for better understanding how the library works let’s make a simpler example of two Arduino boards communicating to each other. Here’s the circuit diagram for this example...
I2C Encoder V2 is compatible with any device that has the I2C bus including Arduino, Raspberry pi, and ESP8266. and you’ll find library and code samples for the first two, as well as the board’s PDF schematics inGithub. The project has raise over 4,000 Euros so far, surpassing its...
The I2C scan shows two sensors, one at 0x41 and the other at 0x29 (which I am aware is the default), but attempts to access at 0x42 returning NACKs. It seems as though the second sensor never gets assigned the new address. I've verified the circuit using Arduino code but cannot ...
The build runs off an Arduino Pro that gets the temperatures from the sensors, prints everything to a custom 7-segment display board, and controls the fan. [Zach] thankfully made the Arduino source available and also put up some board files if you’d like to make your own. It’s a ...
