About

A transistor is an electronic gate, which allows current to flow through it given the correct input. Transistors are needed to help power electronic components which need more than the 5 volts from the Arduino, by acting as a switch. (They can also be used to amplify voltage or current, but this article will talk about the switch function.) There are two types of transistors, NPN and PNP, which accomplish the same goal, but through different methods.

About

I We used the L23D chip with Yourduino[DA2], and was very disappointed with the results. WHAT IS L239D??? It can be used and programmed to a basic robot to cause it to move forward, by command or with a sensor. [DA3]I simply used it as an RC car to pull a sled up-hill as part of Slæde. Another method for using this product, that we didn’t use, could be to program [DA4]it to move when a sensor detects movement.  You could use this for many purposes.

Stepper Motor

 

Stepper Motor

About

A stepper motor is a type of motor which converts electricity into rotations. Each pulse of electricity causes the motor to turn. Stepper motors can also be very accurate in the speed and degrees of their rotation, making them very useful for moving an object to a specific degree. The difference between a stepper motor and a servo motor is that a servo motor uses a continuous rotation DC motor and a controller circuit while a stepper motor uses electromagnets placed around a gear to control its position.

Servo Motor

 

Servo Motor

About

A servo motor is a system of a motor and gears that can make precise movements. A servo motor has a range of movement of 180º. It’s movement is controlled by sending voltage through the yellow wire for a set amount of time and the servo interprets this and moves to the angle specified. This amount of control allows the servo motor to be used for many purposes including robotics, manufacturing and anything that needs to be moved to a precise location.

RFID/NFC Shield

WorldClass Tech

NFC, or, Near Field Communication, allows for different devices to communicate through a radio chat. When the devices are brought within a close range of one another, they can communicate. NFC is almost like bluetooth, but in a smaller range. Unlike Bluetooth, NFC is often used where security is a concern. Because of the close range needed for NFC to connect, the devices must be practically next to each other, making it almost impossible for an eavesdropper to get any data being transferred. NFC is used in an endless amount of products today, such as smartphones, Google Wallet, and even the cards teachers swipe to get into our school.

Sound Sensor

 

About                    

The Adafruit Electret Microphone Amplifier is used to measure sound levels with your Arduino.

Uses

The Adafruit Electret Microphone Amplifier is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. Also, it is great for any project that requires measuring sound levels.
