 Interfacing a Light Emitting Diode (LED) with Arduino What is a LED? A light-emitting diode (LED) is a semiconductor device that produces light when an electric current flows through it. Applications: Indicators, Displays such as Matrix display, Led bulbs etc. Proteus Circuit of Turning on LED Arduino Code void setup() {   // put your setup code here, to run once: pinMode (7,OUTPUT);   // pin 7 (LED pin) configured as an output digitalWrite(7,HIGH);    // command to turn ON LED  } void loop() {   // put your main code here, to run repeatedly: }   Arduino Code for Turning ON/OFF LED Twice void setup() {   // put your setup code here, to run once: pinMode (7,OUTPUT);   // pin 7 (LED pin) configured as an output digitalWrite(7,HIGH);     // command to turn ON LED  delay(1000);                  // command for a 1 second delay digitalWrite(7,LOW);    // co...

  DELAY SWITCHING WITHOUT EFFECT When the delay-switch is excited, a new action on a push button has no effect on the   temporization period. As such, the light goes off after the predetermined time with or without action on the push button multiple times. ENERGY ECONOMIZARION DIAGRAM OF DELAY SWITCH In order to economize the energy, we can: –         - During the day, put off the circuit; –         - During peak hours of functioning, allow the light to shine permanently; –         - During the nights, functioning with the delay-switch.  

DELAY SWITCHING WITH EFFECT 1. FUNCTION OF DELAY SWITCHING WITH EFFECT A delay switch is an electromechanical device used to control a circuit or lighting points from many points within a pre-determined time. 13.2. ARCHITECTURAL  PLAN OF DELAY SWITCHING WITH EFFECT Case study : hall 3.  CIRCUIT DIAGRAM OF DELAY SWITCHING WITH EFFECT When the delay switch is excited, a new action on the push button restarts the temporization period 4. SINGLE-CORE DIAGRAM OF  DELAY SWITCHING WITH EFFECT 5. MULTI-CORE DIAGRAM OF   DELAY SWITCHING WITH EFFECT REMARK : The multi-core diagram of the delay switch is the same as that of the tele-switch, we just need to replace the tele-switch with a delay-switch   5. LOGIC STATE OF DELAY SWITCH WITH EFFECT (CHRONOGRAM)

  TELE-SWITCHING (TELESWITCH) 1. FUNCTION OF A TELE-SWITCH A tele-switch is an electromagnetic device used to control a lamp or many lamps from different positions. A tele-switch can also be called a teleruptor. Example: Control of a lamp from three positions, stair-case, long corridors. 2. ARCHITECTURAL DIAGRAM OF A TELESWITCH Case study : Hall Architectural diagram of a teleswitch 3. CIRCUIT DIAGRAM OF TELESWITCH   We distinguish two circuits: -       The command circuitry: The coil is supplied through the impulse from the push buttons. -       The utilization circuit: the contact « k » of tele-switch controls the lamps. Circuit diagram of a teleswitch 3.1. OPERATION OF A TELE SWITCH – The first impulse supplies the coil K and actions the contact   « k ».   – A second impulse supplies the coil K opens the contact    « k ». REMARK: The control circuit ...
