The M5Stack is a development kit particularly suitable for developing IoT applications (see figure 1). It is Open Source and it is compatible with Arduino. It allows creating IoT applications in a ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

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 first step is a thermistor, a conceptually simple device: resistance varies with temperature (seriously, how much more simple can a sensor get?). You can measure them by tapping the center of a ...

The Raspberry Pi Pico is the new kid on the microcontroller block. How does it compare to the long-established Arduino Nano?

When life hands you a bunch of crummy capacitors, what do you do? Make a whole bunch of temperature sensors, apparently. The less-than-stellar caps in question came to [pyromaniac303] by way of one of ...

Arduino debuted its newest product, a single-board computer called the Uno Q, in conjunction with today’s acquisition ...
