RC522 IC Brief Introduction :

MF RC522 is used in highly integrated 13.56MHz contactless communication card chip to read and write, of NXP for “three” and the application launched a low voltage, low cost, small size, non-contact card chip to read and write, intelligent instruments and portable handheld devices developed better.

The MF RC522 use of advanced modulation and demodulation concept completely integrated in the 13.56MHz all kinds of passive contactless communication methods and protocols. 14443A compatible transponder signal. The digital part handles the the ISO14443A frames and error detection. In addition, support Quick CRYPTO1 encryption algorithm, the term verification MIFARE series. MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transfer rates up to 424kbit / s.

As 13.56MHz highly integrated card reader series chip new family, the MF RC522 MF RC500 MF RC530 there are many similarities, but also have many of the characteristics and differences. Communication between it and the host SPI mode, helps to reduce the connection, reduce PCB board volume and reduce costs.

High Quality HC--SR501 PIR Infrared Sensor Module.

PIR sensors, often referred to as, "Passive Infrared" or "IR motion" sensors, enable you to sense motion.

Everything emits a small amount of infrared radiation (IR), and the hotter something is, the more radiation it emits.

PIR sensors are able to detect a change in average IR levels of their detection zone (e.g. when a human enters a room, that room will increase in temperature slightly) and hence sense motion.

This one's great, as it can be powered via the Raspberry Pi's 5V output, and be read directly from the Raspberry Pi's GPIO input (as the sensor has a digital 3.3V output!)

This PIR includes an adjustable delay before firing (approx 0.5 - 200 seconds), has adjustable sensitivity and two M2 mounting holes.

 It runs on 4.5V-20V power (or 3V by bypassing the regulator with a bit of soldering) and has a digital signal output (3.3V) high, 0V low.

Its sensing range is up to 7 meters in a 100 degree cone.

The SG90 mini servo is lightweight, high-quality and lightning-fast.

Compatible with any servo code, hardware or library.

Servo motors comes with three wires: power, ground, and signal.

Operating Voltage ~5V.

Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places.

HC-SR04 Ultrasonic ModuleDistance Measuring Transducer Sensor for arduino. 

This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately.

The module is with High precision, blind spots (3cm) super close.

This module provides a full set of ranging process.


As any ultrasound sensor, the HC-SR04 operates like a simple radar, by sending a series of pulse waves and listen to an echo.

To measure a distance, start by sending a short trigger pulse to the TRIG pin, at the same time monitor the ECHO pin until the output is HIGH and measure the pulse width.

The distance is equal to (pulse duration in seconds) * (speed of sound) / 2 where the pulse width is in unit of second and sound speed is in unit of meter/second.

Normally sound speed is 340m/s under room temperature.

To use this sensor with the Arduino simply download the srf04-library if you're using the Arduino IDE 1.0 or theUltrasound Library if your IDE version is older.

We recommend a pause of 60-100ms between each distance reading to allow the echo pulse enough time to settle.
