Determine the “zero” values of the voltages and sensitivity along the X, Y, and Z axes for your sensor using the sketch described in the “Calibrating Analog Accelerometer ADXL335” section. Otherwise, the angles and accelerations will be calculated with significant errors.
You can generate sounds using Arduino in different ways. The simplest of them is to connect a piezo emitter to the board (or, as it is also called, a “piezo squeaker”).
The name "reed switch" comes from the phrase "sealed contact." And that explains his device. In fact, a reed switch is a two open (or closed) contacts that are in a vacuum flask, which change their state to the opposite when exposed to a magnetic field.
The development environment for Arduino family boards - the Arduino IDE - has a very modest and low-key look. Many people would like to customize it for themselves, but, unfortunately, so far this opportunity is missing. At least, by means of the development environment itself. However, this possibility is still there. Let's take a look at how to customize the look and feel of the Arduino IDE.
Want to learn how to create electronic gadgets with your own hands, but do not know where to start? Intend to learn the basics of electronics? Then Arduino family cards are a great choice for a beginner. In particular, the Arduino UNO board, which we will now consider, is good for this purpose.
The proposed method of manufacturing weather stations for home or cottage. We take the Arduino board and a set of sensors as a basis: temperature, humidity, pressure and a carbon dioxide sensor.
Hello to all. In this project, we will make a toy automatic garage with the help of Arduino. This toy is unusual and will be very interesting to your kid. Thanks to the HC-SR04 ultrasonic sensor, the garage will automatically open when a car passes in front of it at a distance of about 30 cm and closes after 4 seconds.
Today we will continue to create cool devices based on the Nokia 5110 LCD display. This time we will assemble a luxmeter (the light meter) using a high-sensitive BH1750 luxmeter.
The goal of the project is to study the fundamentals of development for Arduino, the development of technologies for the manufacture of printed circuit boards, the soldering of elements, and the construction of the housing at home.
The development of projects integrating data transfer via Bluetooth involves the transition to more modern ESP32 microcontrollers that support digital data exchange via Wi-Fi, Bluetooth, ADC ports, DAC, audio channels, SD card protocol, the possibility of energy-saving deep sleep mode and a number of other innovations.
