Arduino

I think it is necessary to write that I picked up the idea of the latest program from one programmer, Daniel Shiffman, who makes videos that are understandable even to children about programming in Processing (more than 140 visual tasks have been solved).

Chip M62429 is designed to reduce the volume of sound in electrical circuits. The chip allows you to control simultaneously and independently two sound channels. The sound adjustment range is from 0 to −83 dB, i.e. the chip is able to attenuate the volume about 100,000 times.

A small project in which you will learn to control the LED using Arduino, Bluetooth and Android OS.

In this article, I will tell you about the programs that may be needed in the development process and a few words about them from personal experience. If you want to see a lesson or video on a specific program - write in the comments!

The DS18B20 temperature sensor is a digital temperature sensor. This means that you can measure the temperature using a very simple circuit. It communicates with a common bus, which means that you can connect multiple devices and measure their values using only one Arduino digital output.
The sensor has only three contacts, as you can see in the following figure. The DS18B20 is also available in a waterproof version.

I recently bought a Digispark board. It is compact, cheap and knows how to pretend to be an HID device (keyboard, joystick). So I liked it that I decided to tell you about it, show how to install drivers, make a mini project and share my thoughts about it.

In modern cars, parking sensors are becoming part of the equipment, because it’s really convenient. In the more expensive models, there is also a video camera, which displays an image during a backward stroke, on which the proximity indicator superimposes.
