Introduction Frequency domain analysis is very important to know more about any system/ circuit or transfer function that we deal with. And the first thought comes to our mind about frequency domain analysis is “Bode plot“. Bode plot is a combination plot of magnitude and phase difference of output vs. input of a cosine wave […]

In this blog there are some topics talking about the DHT11 relative humidity and temperature sensor and how to interface it with different types of PIC microcontrollers. The datasheet of the DHT11 sensor shows its characteristics and how it works. Also the following topic shows the DHT11 timing and how to simulate it using Proteus:

Recently, I had the opportunity to test the printed circuit boards (PCB) offered by JLCPCB. These tests were made in two different boards of the brand and here I’ll report my impressions about them. Due to the spread of the maker culture and the do-it-yourself (DIY) and easy access to components and a huge amount
