Electronics - Electronic Components Distributor Light-emitting diode Parts of an LED. Although unlabeled, the flat bottom surfaces of the anvil and post embedded inside the epoxy act as anchors, to prevent the conductors from being forcefully pulled out via mechanical strain or vibration. An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red.
Animatronics Workshop Ultraviolet Portable ultraviolet lamp Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, that is, in the range between 400 nm and 100 nm, corresponding to photon energies from 3 eV to 124 eV. It is so-named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet. These frequencies are invisible to most humans except those with aphakia. Near-UV is visible to a number of insects and birds. PONTECH PIR Sensor (Rev B) Item code: 555-28027 What It Can Do Detects motion of humans or animals from as far away as 30 feetSilent operation for alarms, motion activated nightlights, holiday propsAutomatically resets after period of inactivity Passive infrared (PIR) sensors detect motion by comparing the amount of infrared radiation that reaches a pair of detectors.
Light Emitting Diodes (LEDs) Colour | Sizes and shapes | Resistor value | LEDs in series | LED data | Flashing | Displays Also see: Lamps Example LED: Light Emitting Diodes (LEDs) Colour | Sizes and shapes | Resistor value | LEDs in series | LED data | Flashing | Displays Also see: Lamps Example LED: Circuit symbol: Function How to Analyze Resistive Circuits Using Ohm's Law (with pictures) Ohm's law may be written  in 3 equivalent forms depending on what is being solved for: "V" is the voltage across the resistance (the "potential difference"), "I" is the current through the resistance, and "R" is the value of the resistance. If the resistance is a resistor (a component having a calibrated value of resistance) it is usually labelled with "R" followed by a number, such as "R1", "R105", etc.
