5mm Green Led (Pack of 10) A Green LED( Light-Emitting Diode) is a semiconductor light source which can create green lighting , LED's are used as indicator lamps in many devices and are increasingly used for other lighting. The series is specially designed for applications requiring higher brightness. When an appropriate voltage is applied to the LED terminal, the electrons within the device can recombine with the electron holes and release energy in the form of photons. This is referred to as electroluminescence. The energy bandgap of the semiconductor determines the colour of the LED. If you want to use these green LEDs in your project, there are some components which are helpful are resistors , jumper wires and breadboard

5mm Heat Shrink Tube Black - 1  Meter Heat shrink tube (or, heat shrink tubing) is a tube that shrinks in diameter when heated. After being heated with a heat gun, it shrinks to 50% of its original diameter. Heat shrink sleeve with a completely thermoplastic covered interior surface. When heated, the sleeve's diameter shrinks by 2:1 and the interior resin melts. The sleeve and the resin harden as they cool. This combination ensures resistance to pullout and perfect waterproofing for your connections, preventing a sleeve from slipping. In the case of a connector mounted on a cable (coaxial, for example), this sleeving ensures reinforcement at the point where the cable is generally subject to stress when the radius of the curve is small. To protect the connection, the tubing is wrapped around it and heated with a lighter, matchstick, oven, hot air gun, or similar tool. A soldering iron (held close but not touching the tube) or the heat from a lighter are both convenient but ineffective methods for shrinking the tube. These processes cause the tubing to shrink to one-sixth of its original diameter (depending on the heat shrink, 2:1 is the most common), resulting in a tight fit over irregularly shaped joints. This provides good electrical insulation, dust, solvent, and other foreign material protection, and strain relief. Heat shrink tubing, like any other plastic, can melt, scorch, or catch fire if overheated. Applications: Wire protection Joining Wires Electrical Insulation Cables and Wire bonding

5mm LDR (Light Dependent Resistor) A 5mm LDR photoresistor sensor is made of a high resistance semiconductor. If light falling on the device is of high enough frequency, photons absorbed by the semiconductor give the bound electron enough energy to jump into the conduction band. The resulting free electron (and its hole partner) conduct electricity, thereby lowering resistance. A photoelectric device can be either intrinsic or extrinsic. An intrinsic semiconductor has its own charge carriers and is not an efficient semiconductor, for example, silicon. In intrinsic devices, the only available electrons are in the valence band, and hence the photon must have enough energy to excite the electron across the entire bandgap. Extrinsic devices have impurities, also called dopants, added whose ground state energy is closer to the conduction band; since the electrons do not have as far to jump, lower energy photons (that is, longer wavelengths and lower frequencies) are sufficient to trigger the device. If a sample of silicon has some of its atoms replaced by phosphorus atoms (impurities), there will be extra electrons available for conduction. This is an example of an extrinsic semiconductor. Photoresistors are basically photocells. Sensitivity The sensitivity of a photodetector is the relationship between the light falling on the device and the resulting output signal. In the case of a photocell, one is dealing with the relationship between the incident light and the corresponding resistance of the cell. Learn about the Light Dependent Resistor .

5mm Red Led (Pack of 10) A Red 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.

5mm to 8mm Flexible Coupling The 5mm to 8mm flexible couplings are manufactured with high quality aluminum with minimum backlash possible. These flexible couplings are generally used to connect your driving shaft with the driven shaft. It is able to achieve this in the most efficient and possible way while avoiding any misalignment. Flexible shaft couplers used in small CNC machines and 3d printers such as prusa i3. Flex capability of the coupler removes stress when shafts are not aligned perfectly. Features: Helical cut makes them behave like a springy in the X Y and Z linear axis but not in the rotational axis. That means that you won’t get more backlash, hence they are suitable for precision CNC work. A coupling is a device which transmits power and torque. Couplings do not normally allow disconnection of shafts during operation. However, there are torque limiting couplings which can slip or disconnect when some torque limit exceeds. By careful selection, installation and maintenance of couplings, substantial savings are possible in reduced maintenance costs and downtime. It can protect the driving and driven shaft members against harmful effects because of misalignment of the shafts, sudden shock loads, shaft expansion or vibrations etc. Applications: Connects gears, rods etc. to the 5V stepper motors Commonly used for Robotics, 3D printer and other projects.
