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...

TLP281 4-Channel Opto-isolator IC Module Features Sometimes we need to separate the low-voltage section (microcontroller) from the high-voltage one in circuit in order to prevent noise and damage to the microcontroller. This module isolates the low-voltage section from the high-voltage section using TLP281-4 IC. This IC contains 4 LEDs (Light Emitting Diode). 4 high-voltage channels can be controlled by microcontroller using this IC.This module can also be used to turn on and off the servo motor and oth...

PCF8563 RTC Module Features The PCF8563 real time clock module features high accuracy and low power consumption. This RTC maintains seconds, minutes, hours, day, date, month, and year information. In this module, the date is set based on whether the month is 29, 30 or 31 days and also it is leap year or not. This module can also be used in 12-hour and 24-hour formats. DS3231 RTC Module Pinout This module has 6 pins:INT: interrupt outputCOT: Clock outputSCL: Seria...

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 ...

0.96 INCH I2C/SPI OLED Display Module 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. The driver chip is SSD1306, which provides I2C/SPI communication. You can download the datasheet of this module here.  [wpdm_package id='19894'] 0.96 INCH OLED Display Module Pino...

1.3 INCH OLED Display Module 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. The driver chip is SH1106, which provides I2C/SPI communication.

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. ...
