Out of stockPro Micro 5V 16M Mini Leonardo Microcontroller Development Board For Arduino
[Arduino Boards] This Pro Micro 5V 16M Mini Leonardo Microcontroller Development Board For Arduino development board has 4 channel 10 bit ADC, 5 PWM pins, 12 DIO, and a hardware serial connection Rx and Tx you are familiar with Running on 16MHz and 5V, this board will remind you a lot of other Arduino compatible boards that you like. There is a voltage regulator on board, so it can accept up to 12V DC. The Micro is a microcontroller board based on the ATmega32U4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard. The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. If you supply an unstable power supply board, be sure to connect to the “RAW”, not on the VCC pin. It has also added a PTC fuse and diode protection to the power circuit and to correct the RX and LED TX circuits. Features : ATMEGA32U4 running in 5V / 16MHz Support Arduino IDE V1.0.1 Micro USB interface programming on the board Four 10-bit ADC pin 12 digital I / O (5 PWM capability) Rx and Tx hardware serial connection.

Out of stockPiezo Electric Active Big Buzzer B27
[Buzzer And Mic] 5-24V Buzzer Continues Beep – Big 27 A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke. A piezoelectric element may be driven by an oscillating electronic circuit or other audio signal sources, driven with a piezoelectric audio amplifier. Sounds commonly used to indicate that a button has been pressed are a click, a ring, or a beep. Voltage: 5 V Sound : 90dB Housing Material: ABS Plastic. Perfect for motorcycle stand alarm, alarm clock, or any project which you need an alarm buzzer for getting immediate attention. Note: This product comes in different design patterns. We ship randomly.
Out of stockHigh Current Active Alarm Buzzer Driver Module
[Current Sensor] A High Current Active Alarm Buzzer Driver Module is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Just like what you are viewing now, it is 5V DC Electronic Part Active Buzzer Module. Using top quality material, it is durable in use. What’s more? This 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. A good choice for you all! Features: 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.

Out of stockLeonardo R3 Board Micro-USB compatible with Arduino
[Arduino Boards] The Leonardo R3 Board Micro-USB compatible with Arduino is a micro-controller board base on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs); a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything need to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. The Leonardo R3 Board differs from all preceding boards in that the ATmega32u4 has built-in USB communication; eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard; in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board.
