This IR reflective sensor utilizes a TCRT5000 to detect color and distance. It emits IR and then detects if it receives the echo. This sensor is often used in line following robots, auto data logging on utility meters, because this module can sense if a surface is white or black. The measuring distance range from 1mm to 8mm, and the central point is about 2.5mm. There is also an on-board potentiometer to adjust the sensitivity. The infrared diode will emmitting the infrared continutelly when the module connect to the power, when the emitted infrared light has not been reflected or the strength is not big enough,the triode will in the off state, at this time, D0 output logic LOW and the signal indicate LED off.

USB to UART Converter is a very useful tool for Embedded Systems. If you haven’t one, please try to buy it. It will definitely boost development speed of projects which uses UART modules like interfacing GSM, GPS, Bluetooth, Wi-Fi et. By using it we can easily study these modules by sending data directly from your PC and analyzing the received data in your computer display without programming a microcontroller. Here we will use PL2303, one of the most popular USB to UART Converter manufactured by Prolific Technology Inc.

Standard Charging Voltage: 3.2 ~ 4.2V Overcharge release voltage: 4.23±0.05V Overcurrent detection current: 2.5A

The SD Card Shield is a simple solution for transferring data to and from a standard SD card. The pinout is directly compatible with Arduino, but can also be used with other microcontrollers. It allows you to add mass storage and data logging to your project.

A unipolar stepper motor has one winding with center tap per phase. Each section of windings is switched on for each direction of magnetic field. Since in this arrangement a magnetic pole can be reversed without switching the direction of current, the commutation circuit can be made very simple (e.g., a single transistor) for each winding. Typically, given a phase, the center tap of each winding is made common: giving three leads per phase and six leads for a typical two phase motor. Often, these two phase commons are internally joined, so the motor has only five leads.

'-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.
