28BYJ-48 Stepper Motor Features We usually use stepper motors when we need precise control of the motor shaft. These motors can be used in robot arms, 3D printers, CNC machines, etc. Stepper motors convert electrical pulses into discrete mechanical movement. The resolution and rotation speed of the motor shaft depend directly on the frequency of the input pulses. One of the most important advantages is that they can control precisely in an open loop system.28BYJ-48 Stepper motor is one of these motors....

Single Axis 1:120 Gear Motor Features If you work in electronics and robotics field, you have come across DC motors at least once. These motors are one of the most widely used elements in electronics and robotics. These motors convert direct current electrical energy into mechanical energy.An external source provides power for the stator of these motors. As a result, the current flowing through the stator creates a uniform field under the poles. Of course, permanent magnet can supply the stator field, ...

XKC-Y26-V Non-contact Liquid Level Sensor Features The XKC-Y26-V Non-Contact Liquid Level Sensor is a digital output sensor that detects the presence of liquid. There is an LED on the module, which will turn on if liquid is detected, otherwise it turns off. There is also a screw on the body of the module that you can use to adjust the sensitivity of the sensor. This sensor is suitable for dangerous applications such as detection of toxic substances, strong acids, strong alkalis, etc. ...

Overview In this tutorial, you will learn how to use a soil moisture sensor. Practical examples are also provided to help you master the code. What You Will Learn How soil moisture sensors work How to use soil moisture sensor with Arduino Soil Moisture Sensor - How Does It Work? The soil moisture sensor consists of two probes that measure the volume of water in the soil. The two probes allow the electric current to pass through the soil and, according to its resistance,...
