Discover how to effectively interface the IRF520 MOSFET Driver Module (HCMODU0083) with Arduino in this step-by-step tutorial. Learn about the key features of this module and explore its applications in controlling DC motors using Pulse Width Modulation (PWM) technique. With the ability to convert a constant input voltage to a variable voltage, this module allows precise control over the speed of your DC motor. Whether you're a beginner or an experienced Arduino enthusiast, this guide will help you master t...

Heart Rate Pulse Sensor Features Heart Rate Pulse Sensor can be used to measure the heart rate and some related parameters such as cardiac arrhythmia (i.e., abnormal heart rhythm). If you touch this sensor with any area of your skin that is closest to the arteries (such as the finger or earlobe), the sensor detects blood in the arteries. Each time the heart beats, blood is pumped through the arteries, and the sensor detects the flow of blood and increases the output voltage. Note This sensor has an analog o...

SW-520D Vibration Tilt Sensor Features The SW-520 sensor consists of two metal balls which switches as a trigger. When the switch is positioned horizontally, and when the sensor angle is less than 10°, the circuit is open (off state) and more than 10°, it is closed (on stated). But when the switch is positioned vertically, the circuit is open when the sensor angle is less than 45°, and close when the angle is more than 45°. To see exactly how this sensor works, read the datasheet. The SW-520D sensor is ...

OMRON Photoelectric Sensor Features The Omran photoelectric sensor can be used to detect obstacles and objects at 5 to 100 mm distance. There is an LED on the sensor that is always off and turns on when it detect an obstacle. You can also change the LED status using the potentiometer which is on sensor. (That is, the LED is always on and will turn off when the obstacle is detected.) There is another potentiometer on the sensor that can be used to change the sensitivity of the sensor (increase or decrease th...

PS2 Joystick Module Features This module consist of two joysticks and two independent buttons. The joystick is very useful in robotics. Each joystick has two potentiometers on two X and Y axes and one push button. This module has two analog outputs and one digital output. In robotics, it can be used to control moving parts and motors. How it works This module contain two potentiometers in both X and Y axis. As shown below, the joystick is normally in the ...

0.95 INCH OLED Display Features OLED displays are high contrast and high-resolution displays, so they provide a good readability for users. There is no backlight on OLED, and it uses independent-illuminated pixels. So it is thinner, and more elegant in compare to LCDs.This 0.95-inch colorful OLED is graphic type, the resolution is 96x64 pixels and the chip driver is SSD1331. You can download the datasheet of this module here.  [wpdm_package id='19883'] 0.95 INC...

KY-008 Laser Transmitter Module Features This Laser module emits a small intense focused beam of visible red light.  The operating voltage is 3-5 V and the required current is 40mA. Note Since the required current is 40 mA and the Arduino pins can supply this current, this module can be connected directly to Arduino. If need be more than 40mA, direct connection to Arduino will damage the Arduino. In that case, you need to use a laser driver to connect the laser module to Arduino. ...

RepRapDiscount Full Graphic Smart Controller Features Using the RepRapDiscount Smart Controller, you don’t need a computer to control 3D printer anymore. In this shield, an SD card is used to transfer 3D design to 3D printer and store the G-Codes. This full graphic Smart Controller contains a 128 x 64 dot matrix LCD display. Using the rotary encoder on the board, you can move around in the device menu and access data. This display is compatible with ramps 1.4 controllers and can be run with marlin and rep...

DRV8833 Dual Motor Driver Features Today, speed and direction control of DC motors is very important and useful. The H-bridge circuit is one of the most common techniques to control a DC motor. The DRV8833 dual-channel module uses this technique to control two DC motors.This dual H-bridge motor driver can drive two DC motors, a stepper motor or other inductive loads.The driver supply voltage is 2.7 to 10.8V and the allowable continuous current is 1.5A and the maximum allowable current is 2A.Some common...

DRV8825 Stepper Motor Driver Features The DRV8825 module is used to drive a bipolar stepper motor. Only by two pins, you can control the rotation direction and rotation steps of the motor. By each signal sent by the spin step pin, the motor shifts one step. The key features are:This driver has 200 steps per revolution in full step (1.8 degrees per step).Allowable continuous current per phase without cooling: 1.5AMaximum current per 24V for each phase: 2.5AMotor voltage: 8.2 to 45VThe minimum allowed ...
