We are living in the world where everything goes to be automatic from your washing machine to your ceiling fan. Street lights are one of those example of automatic world.Automatic street light are those light which needs no manual operation to gets turn ON and turn OFF . Did you ever tried to make such kind of street lights that gets turn ON and turns OFF automatically? In this article we are going to make automatic street light using LDR and 555 timer IC. List of Components 555 Timer ICLDRLEDPo.......

. ha dejado un nuevo comentario en su entrada "El Flip Flop Tipo T como interruptor on/off":hola. . . disculpa tengo la intencion de hacer un circuito sobre una lampara para que esta pudiera apagarse y prenderse con ruido o algo similar y que la intensidad de luz se pueda regular aumentando o disminuyendo segun se necesite pero para esto la lampara serian esencialmente leds de alta luminosidad colocados sobre una rama (literal)komo un arbol con leds. . y vi tu articulo pero no se de electronica .......

El LDR (resistor dependiente de la luz) es una resistencia que varía su valor dependiendo de la cantidad de luz que la ilumina. 
LDRSu símbolo es: 
Los valores de una fotorresistencia cuando está totalmente iluminada y cuando está totalmente a oscuras varía. Pu.......

This was an attempt to declutter our bedroom. I had grown weary of the clutter next to the bed and decided to make a nightstand that matched the ALF Group bedroom set we purchased from Italy. In this hybrid project, I combined woodworking, mechanics and electronics to create a nightstand that hid away our clock, X10 light control and any other clutter that potentially could pile up. Microswitches inside the front panel of the nightstand control the raising and lowering of the hidden compartment........

There are many applications when a remote switch’s on/off status needs to be monitored. Reed relay sensors, toggle control switches and security alarms contacts are just a few examples. Routing a switch directly to a computer system hundreds of feet away can often lead to erratic operation and noise problems. If such a control switch is required, a fully isolated circuit ..........

Single plate induction cooker demonstration board Uses ST7LITE09 and STGW40NC60WD (40 A, W series). The design is entirely controlled by a simple ST7FLITE09Y0 8-bit microcontroller, which provides the PWM driving signals, communicates information to the user interface, and drives the fan and relay control to the plate feedback. With Single Voltage Flash Memory, Data Eeprom, Adc, Timers, Spi ........

The circuit requires a double pole, double throw relay in conjunction with a single transistor to allow toggling the relay with a momentary push button. One set of relay contacts is used to control the load, while the other is used to provide feedback to keep the relay activated or deactivated. Several push buttons can be wired in parallel to allow toggling the relay from different locations........

High-Temperature Thermometer/Thermostat - Need to measure or control temperature over a very wide range? Now you can do it with this compact unit which hooks up to a K-type thermocouple. It drives a relay which can be used to precisely control the temperature in ovens, kilns, autoclaves, solder baths or at the cold end of the spectrum, fridges and freezers. It is based on an Analog Devices AD8495 precision instrumentation amplifier with thermocouple cold junction compensation. Need to measure or.......
