This isn’t about connecting a temperature sensor in your Arduino. This build is about using ... s clearly in the datasheet seems not to be used by many people. Thanks [jan] for sending this ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures ... The two 4.7K pull-up resistors must be used when using I2C ...

In my case I used the well-known BD139 transistor and a 9V battery to provide power to the fan and transistor. The LM35 temperature sensor and red led are powered with 5V from the Arduino board. As ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at ...

it’s defined right there in Arduino.h. Great stuff! The I2C (“Wire”) library has also gotten the ESP32 treatment, and worked just as it should with an LM75 temperature sensor. This is my ...
