➡️ How to connect analog accelerometr ADXL335 to Arduino

Daniil Zhuk
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.

🔍 How to connect a reed to Arduino

Daniil Zhuk
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.

🔄 How to change the appearance of Arduino IDE

Daniil Zhuk
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.

🚗 Automatic toy garage (Arduino project)

Daniil Zhuk
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.
