Welcome to My BlogIn my development section more unfinished articles than here in the open access. I think everything has its time. I heard that Noel Gallagher writes his songs in the same way. This all happens because for both of us this is a creative process that requires a lot of time.  In the heap of old junk I came across the remains of some old audio/video equipment and I had a desire to test the display which had the marking "BC-M06233G", "PQ060B", "HW-1" and "94HB", but unfortunately my search for datasheets on the Internet...
 As it is known, the microcontroller for obvious reasons can control the electromagnetic relay only through a special driver and most often this driver is the simplest transistor switch. In this article I will calculate the transistor switch for the relay TRS-12VDC...

 Old boards with relays that are controlled by transistor switches are an excellent source of ready-made (already calculated) relay modules for Arduino. Below is a photo of the board from the old air conditioner indoor unit control module of 2007 issue...
 The DJI Mavic Pro is a small yet powerful drone that turns the sky into your creative canvas easily and without worry, helping you make every moment an aerial moment. Its compact size hides a high degree of complexity that makes it one of DJI's most...

 H27VI5 is an all in one solution for monitoring voltage and current. This device has several modifications but I want to consider the option with a measurement limit of 100V/10A which has a built-in shunt. Due to the fact that the colours of the wires...
 Variations of gray include achromatic grayscale shades, which lie exactly between white and black, and nearby colors with low colorfulness (chromatic gray). Below is a charts showing the computer web color grays...
