These are some great DIY projects that you can do for cheap.

There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...

This is an accurate LM35 analog temperature sensor library for Arduino with noise cancellation. This library changes analog pins to ADC 1.1V internal reference voltage which affects all analog pins.

We built this Arduino-based Digital Thermometer for temperature measurement applications. Thermometers have been useful for temperature measurement for a long time. A digital thermometer is an ...

If you are looking for an inexpensive, accurate, easy-to-use temperature sensor, then LM35 is an excellent choice. It has an accuracy of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C ...

Graphs are always helpful to visualize the data and it becomes very easy to find trends and patterns by looking at them. There are many software available to plot graphs based on the input values, ...

Arduino is a great way for today’s novices to start to learn how to write and run codes that interact with the external world. Somebody on Facebook recently asked about finding an easy-to-use shield ...

The measurement and analysis of process parameters such as temperature, flow, conductivity, speed, viscosity and stress play a crucial role in providing information about the process/system under ...
