In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. The voltage drop across a lit LED is approximately constant over a wide range of operating
A single or a few LED junctions may be packed in one miniature device for use as an indicator or pilot lamp. An LED array may include controlling circuits within the same package, which may range from a simple resistor, blinking or color changing control, or an addressable controller for RGB devices. Higher-powered white-emitting devices will ...
Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
Improved: FT232BM has been replaced by FT232RL to require fewer external components, LED on pin 13 added Arduino NG plus ATmega168 [39] 16 MHz Arduino 81.3 mm × 53.3 mm [ 3.2 in × 2.1 in ] USB Arduino BT (Bluetooth) [54] ATmega168 [39] ATmega328 [33] 16 MHz Arduino 81.3 mm × 53.3 mm [ 3.2 in × 2.1 in ] Bluetooth: Bluegiga WT11 Bluetooth
The concept of developing is to write a few lines of code, connect a few electronic components to the Wiring hardware and observe, for example, that a motion sensor controls a light when a person approaches it, write a few more lines, add another sensor, and see how this light changes when the illumination level in a room decreases.
Sun SPOT – hardware–software platform for sensor networks and battery powered, wireless, embedded development; USRP – universal software radio peripheral is a mainboard with snap in modules providing software defined radio at different frequencies, has USB 2.0 link to a host computer
Schematic diagram of an opto-isolator showing source of light (LED) on the left, dielectric barrier in the center, and sensor (phototransistor) on the right [note 1]. An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. [1]
A Charlieplexed digital clock which controls 90 LEDs with 10 pins of a PIC 16C54 microcontroller.. Charlieplexing (also known as tristate multiplexing, reduced pin-count LED multiplexing, complementary LED drive and crossplexing) is a technique for accessing a large number of LEDs, switches, micro-capacitors or other I/O entities, using relatively few tri-state logic wires from a microcontroller.
