      Anti- Theft Alarm Using 555 IC This is an simple project to prevent the object from thefting. Let us discuss this project below. Components Required    1.      555 IC 2.      10K ohm resistor 3.      10uf capacitor 4.      LED 5.      BreadBoard 6.      Connecting Wires 7.      9v Battery Circuit Diagram Procedure      · Insert the 555 IC in the breadboard and then connect resistors and capacitor shown in figure · Then insert an single piece wire at the 8 th terminal of 555 IC · Then insert the another single piece wire at the 1 st terminal of the 555 IC · Next connect an LED to the 3 rd pin of the 555 IC and connect another end of Led to ground · Now, connect it to the power supply. When the 8 th and 1 st pin have been shot circuited with the wire the Led do...

                             POTENTIOMETER                                                Generally the potentiometer is an three terminal  adjustable resistance in which the voltage is varied and given. Thus it is know as the variable resistance. The potentiometer is used in various system for adjustable power supply. It is classified as ·       Rotatory(Most commonly used potentiometer) ·       Slider                                                    Let demonstrate with it by simpl...

BLUETOOTH  CONTROLLING USING ARDUINO      The Arduino is the basic programmable logic circuit in which it allows to control appliances in easiest way. The Bluetooth module is used for sending and receiving     data wireless by means of electromagnetic waves. Thus it sends data so we can control appliances wirelessly. Connections:                              Vcc -> +5V                             Gnd-> Gnd                              TX->RX               ...
