Bring oscillation source Audino 9012 drive Work Voltage:3.3V-5V Set bolt hole, easy to assemble PCB Dimension:3.3cm*1.3cm It and your Arduino will be able to play melodies. This is a small buzzer for the Sensor Shield. It creates different sound based on the different frequency of I/O toggling. Pin Definition : Vcc : 3.3V-5V GND : The Ground I/O : I/O Interface of SCM

'-The lamp brightness can be adjusted by requirement,it is very to operate. -It can touch in medium protection,such glass,acrylic,plastic,ceramics and so on,which is very safe. -Wide application of voltage range,you can choose arbitrarily between 2.4V to 4.5V. -Anti power and phone interference,the EFT can reach above /-2KV;the touch response sensitivity and reliability will not affected by the close distance or multi-angle mobile phone interference. -Install: Needn’t to touch copper foil directly,the dimming can be processed across acrylic glass(above 3mm) or plastic. -Application:It can control LED module,light and so on.It is available for indoor LED,lighting lamp,DIY automotive lights dimming refit. -Function:Single touch,using the principle of capacitance touch .-The default function is switch,dimming,with brightness memories LED touch dimming.It will light slowly when turn on the lights,and become dark slowly when turn off,which effectively avoid the stimulation to eyes. -Dimming mode:Non-polar PWM dimming. -Wiring method:PCB board(VCC,GND) is power input,(LED , LED-) is connected with the LED lamps of positive and negative level (fingerprint) touch area, also can wire to lead out (the wiring should not be too long), copper skin area should be 2x3cm. With copper foil copper foil board module will side to the shell side.

Description: The module is used in chip TM1638, a collection of these three common MCU peripheral circuit, the biggest feature is just take three microcontroller IO port to drive, do not need to scan display and key scanning microcontroller intervention, only need to read the relevant register send display data or test button, save MCU resources. We usually use an external microcontroller 8 LED, 8 digital tube, eight keys which will occupy the number of IO ports, far more than three IO mouth it, but with this module can be achieved. The practical application of key sensitive display good results. Wiring: VCC GND connected to 5V power supply, STB CLK DIO connected microcontroller IO port.

This shield V03 can achieve a simple two crunodal ZigBee network，achieve wireless communication between Arduino ，and allows the Arduino to wireless communicate over a modified ZigBee protocol using the popular XBee module.It works with all XBee modules including the Series 1 and Series 2.5, standard and Pro versions.

'-24V 2-Channel Relay interface board, and each one needs 50-60mA Driver Current. -Equipped with high-current relay, AC250V 10A ; DC30V 10A. -Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). -Indication LED’s for Relay output status.
