PROPELLER CLOCK OBJECTIVE :- In this project‚ our aim is to use PIC or 8051 microcontroller to control a row of LEDs to function it as a clock. ABSTRACT :- The Propeller Clock is an electronic device which has a series of LEDs on board that rotate with the help of a motor to give an illusion of a watching a clock ( Digital or Analogue ). This requires a DC motor which rotates the PCB connected to it with sufficient speed so as to create the illusion. The LEDs are connected to a microcontroller

EE213 Electrical Circuits Laboratory Term Project Two Speed Automatic Transmission System 1. Introduction Transmission system is an assembly of gears‚ shafts and electrical gadgets in an automobile. This system forms a bridge between the engine and wheels to transmit mechanical power required for movement. The complete set up reduces the high rotational speed of engine to lower wheel speed‚ since internal combustion engines in automobiles operate between 600 and 7000 revolutions per minute (rpm)

INTRODUCTION For years‚ infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now‚ infrared LED has evolved into a system of significantly greater importance and use. Throughout the world‚ it is now being used to transmit voice‚ television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result‚ millions of dollars are being spent

So‚ today I have the Gigabyte GA-Z170X-Gaming G1 motherboard based on the LGA 1151 socket which allows support for Intel’s 6th generation Skylake processor for review‚ and I don’t know where to start! It has a plethora of features‚ looks stunning and compliments the new chipset’s rich connectivity. The GA-Z170X-Gaming G1 is the top of the line motherboard from the gaming series of Gigabyte. It’s one of the most feature packed motherboard that I’ve reviewed so far and offers some of the latest features

Abstract—We focused on Buck/Boost Rectification by Single Phase Matrix Converter with fewer numbers of switches. The conventional matrix converter consists of 4 bidirectional switches‚ i.e. 8 set of IGBT/MOSFET with anti parallel diodes. In this proposed matrix converter‚ only six switches are used. The switch commutation arrangements are also carried out in this work. The gate pulses to the switches are provided by the PWM techniques. Step up or step down DC outputs can be obtained by using suitable
