IC  LM556  Dual Timer : Description, Features and Applications.

Description

   The LM556 Dual timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. The 556 is a dual 555. Timing is provided by an external resistor and capacitor for each timing function. The two timers operate independently of each other sharing only VCC and ground. The circuits may be triggered and reset on falling waveforms. The output structures may sink or source 200mA.

 Door Alarm using SCR    SCR ( silicon controlled Rectifier) also called Thyristor is a  semiconductor controlled rectifier is a four layer solid state current controlling device. Components : 1. 1 × Low Power scr 2. 1 × 9v Battery 3. 1 × buzzer 4. 2 × Switches 5. 1 × 1k ohm resistor ( may be vary) Circuit Diagram : Door Alarm system using SCR Working : 1. Make circuit as per Circuit Diagram. 2. Place switch in on door in that way when door is open, switch is closed. 3. When Switch is closed a triggering pulse apply to gate and scr is turn on. Attention :   To turn off  buzzer place one more switch between positive terminal and scr anode. OR remove Battery

Low Power Inverter : Electronics Mini projects

 Low Power Inverter : 12DC into 230-250V AC     Here is a  simple low-power inverter that converts 12V DC Into 230-250V AC. It can be used to power very light loads like Window chargers and night lamps, or Simply give shock to keep the intruders away. The circuit is built around Just two ICs, namely, IC CD4047 and IC ULN2004.      IC CD4047 (IC1) is a monostable / astable multivibrator. It is wired in astable mode and produces symmetrical pulses of 50 to 400 Hz, which are Given to IC2 via resistors R1 and R2.    IC ULN2004 (IC2) is a popular 7-channel Darlington array IC. Here, The three Darlington stages are Paralleled to amplify the frequencies Received from IC1. The output of IC2 Is fed to transformer X1 via resistors R3 and R4.     Transformer X1 (9V-0-9V, 500mA Secondary) is an ordinary step-down Transformer that is used here for the reverse function, i.e., step up. That Means it produces a high voltage. Resistors R3 and R4 are used to limit The output current from the ULN
