3.5-5.5V Standard Active Buzzer Module For Arduino
A Standard Active Alarm Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. This PCB Mounted Active Buzzer Module can produce a range of sound tones depending on the input frequency, i.e it can generate tones between 1.5 to 2.5 kHz by switching it on and off at different frequencies either using delays or PWM.An active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.This module is ideally suited to adding noise to your project and is compatible with a pin pitch of 2.54mm while functioning with microcontrollers such as the Arduino. This module lets you respond to programmatic changes with a lovely annoying buzzer that can be altered over a range of frequencies to ensure maximum irritation. To operate the I/O pin must receive a square wave to trigger the buzzer. This can be produced within all popular microcontrollers.Specification:- Working voltage: 3.5-5.5V
- Working current: <25mA
- PCB Dimension: 1.85 x 1.5 cm (L x W)
Feature:
- An active buzzer with a concussion internal source- so long as it will be called an energized
- The program easy to control- SCM can let a high-low sound- while passive buzzer did not.
- The Transistor drive module uses 8550
- With fixed bolt hole- easy installation- 2.6mm aperture.

This combo containing all products needed to make a smart dustbin that opens automatically when someone comes near to the dustbin.
The Arduino Uno R3 Compatible Board is a microcontroller board that is based on the ATmega328. Arduino Uno has 14 digital input or output pins, 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It has everything needed to support the microcontroller, you need to simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.This HC-SR04-Ultrasonic Distance Measuring Sensor is a very popular sensor that is found in many applications where it requires measuring distance and detect objects. The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object like bats or dolphins do. The module has two eyes-like projects in the front which form the Ultrasonic transmitter and Receiver.
The Micro Servo 9G is lightweight, high-quality, and lightning-fast. The servo is designed to work with almost all radio control systems. It is with excellent performance that brings you to another horizon of flight.
This is the combo of 20CM Wire Color Jumper Cable, M-M, M-F, F-F 10PCS of wire in each strip of cable. It is very flexible and easily detachable to no. of wires to your requirement. Mostly it can be used for Orange Pi, Banana Pi, Raspberry Pi, Arduino, and other mini PC and development boards.
This is a general 9v Battery With Battery Snap Connector to DC barrel jack adapter for all your project and application needs. One can use this adapter to power up any DC barrel jack-based power connector using a standard 9V battery.
Package Includes:
1 x Arduino UNO R3 Compatible Board With Cable

Arduino Sensors Combo of 5 Kit
This is a basic combo for Arduino and Robotics starter. This set can be used for obstacle sensing cars, Ultrasonic radars, school projects i.e. automatic barrier, automatic light, etc. This combo includes an ultrasonic sensor, motion sensor, IR obstacle sensor, LDR, SG90 Servo motor.
HC-SR04-Ultrasonic Distance Measuring Sensor is a very popular sensor that is found in many applications where it requires measuring distance and detect objects.
HC-SR501 PIR Motion Detector Sensor Module is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.
IR sensor module is adaptable to the environment, with a working voltage of 3.3 V to 5 V. It has a pair of infrared transmitting and receiving tubes when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving by the tube.
Photoresistor also is known as LDR(Light Dependent Resistor) as the names imply, changes the resistance with the variation in the amount of light. This particular photoresistor has a resistance of 5-10k Ohm in light and about 500k Ohm resistance in the dark.
Micro Servo 9G is lightweight, high-quality, and lightning-fast. The servo is designed to work with almost all radio control systems. It is with excellent performance that brings you to another horizon of flight. The SG90 mini servo with accessories is perfect for R/C helicopter, plane, car, boat, and truck use.
