2M 3296W Trimpot Trimmer Potentiometer (Pack of 5) 2M 3296W Trimpot is a high accuracy variable resistor and PCB mountable with 3 terminal pins. A general-purpose board mountable preset also called by other names like potentiometers, Trimpots, etc but is just a variable resistor. The voltage between the terminal varies as the trimpot is rotated. The Variable resistors are used for variating voltage as per the need in a circuit. The outer two pins are connected to Vcc and 0V, and the center pin outputs a variable voltage between 0v and Vcc as the rotary cermet is rotated. The potentiometer is easy to mount on a PCB and can be adjusted using a screwdriver. This potentiometer has a single turn, which can be used to preset a value. Applications Can be used to adjust the voltage drop in the circuit Measurement and Test of electronic circuits Can be used to control the intensity of led lights in DIY projects

2N2222A NPN Transistor (Pack of 5) The PN2222A is a common NPN BJT used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, and medium voltage, and can operate at moderately high speeds. 2N2222A is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits. The 2N2222 NPN Transistor is made in the TO-18 metal can as shown in the picture. Replacements are commonly available now in the cheaper TO-92 packaging, where it is known as the PN2222 or P2N2222, which has similar specifications except for the lower maximum collector current. read more : What is a 2N2222A Transistor & Its Working Applications: This transistor can be used as a switch for automatically switch ON/OFF any appliances. It is used for PWM due to its quick response Because of its fast response time, it can be used for pulse width modulation. Home automation & embedded projects. Audio Preamplifiers Audio Amplifier Stages Used to switch several loads simultaneously Darlington Pairs These transistors are used in Motor drive circuits like VFD or variable frequency drives.

3 mm Yellow LED (Pack of 10) A Yellow light-emitting diode (LED) is a semiconductor light source. LED's are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white led and illuminate's blue light. When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the colour of the light (corresponding to the energy of the photon) is determined by the energy bandgap of the semiconductor. read our blog about Turning on an LED with your Raspberry Pi’s GPIO Pins which explains controlling led with raspberry pi .
