What is a breadboard? A breadboard is used to build and test circuits quickly before finalizing any circuit design. The breadboard has many holes into which circuit components like ICs and resistors can be inserted. A typical breadboard is shown below: The bread board has strips of metal which run underneath the board and connect the holes on the top of the board. The metal strips are laid out as shown below. Note that the top and bottom rows of holes are connected horizontally while the

vehicle. The heart of the circuit is a 555 timer IC‚ wired as an astable multivibrator in the circuit. A 2N3773 high current transistor is also used in the circuit and working as a switch and it is derived from the output pin 3 of the IC through a 1K resistor. The IC generates continuous pulses on its pin 3 which makes the transistor switch ON and OFF continuously. When the transistor will be in the switched ON state the 12 volts from the battery starts passing through it and activate the lamps and in

About Passive Components A passive component is a module that does not require any source of energy to perform its function in any given application. Capacitors‚ inductors‚ and resistors are the main types of passive component. They are used to control the intensity of the current or voltage in a circuit. Passive components are used in industry to improve the energy efficiency‚ life‚ and performance of devices such as lighting . They are also used in medical equipment to improve precision and

This is done by a sensor called Light Dependent Resistor (LDR) which senses the light. The arduino is serves as the microcontroller of the system. As the system managing the high voltage output even the power supply of arduino is almost 9-12 V it use relay to manage the output that 220V and above. Saving

Such basic components are fairly limited in number and each having their own characteristic function. Memristor theory was formulated and named by Leon Chua in a 1971 paper. Chua strongly believed that a fourth device existed to provide conceptual symmetry with the resistor‚ inductor‚ and capacitor. A device linking charge and flux (themselves

CHAPTER I ------------------------------------------------- INTRODUCTION 1.1 Introduction Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless

An additional resistance‚ which is called shunt resistor‚ is placed in parallel with the galvanometer of an ammeter to extend the range of the DC ammeter. The added resistance must be less than the resistance of the galvanometer to attract more current and the ammeter itself will receive less current‚
