[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

When they need to add temperature control to a project, many hackers reach for a K-type thermocouple for their high-temperature needs, or an integrated temperature-sensing IC when it doesn’t get that ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

The ESP32-H2 microcontroller offers ultra-low power for Zigbee smart home devices. It draws just 20mA compared to the 77mA of the ESP32-C6.

In my early ESP32 tinkering days, I’d only use the microcontroller to test with LEDs, resistors, and other circuitry components. In fact, writing simple C++ programs to perform basic tasks on the ...

So you finally decided to hop on the Arduino bandwagon and start making electronic projects as a fun hobby. As a beginner getting started with Arduino, your first instinct is typically to buy a ...
