Now a day’s many school/college bells are manually operated. Hence there is a huge demand of accuracy. In market there are many digital clocks available with bells but rings only at specific time and cannot stop after specific time. Here a new and inexpensive design is being presented. The benefit of this design is that the bell rings at the start of each period without any human intervention to a great degree of accuracy and hence tak […]

Speed control of a machine is the most vital and important part in any industrial organization. This paper is designed to develop a four quadrant speed control system for a DC motor using microcontroller. The motor is operated in four quadrants i.e. clockwise, counter clock-wise, forward brake and reverse brake. It also has a feature of speed control. The four quadrant operation of the dc motor is best suited for industries where motor […]

T-junction traffic light controller is such a device that will play a significant role in controlling traffic at junctions, to ease the expected increased rush at such junctions and reduce to minimum disorderliness that may arise, as well as allowing the pedestrians a right of the way at intervals rather than being struck down when in a hurry to cross the roads. Such an electrical system with a touch of electronics that control the flo […]

The design of the PIC microcontroller LED clock consists of few components that implement a solar powered digital street clock using LED display pattern. In this paper the LED clock was designed with 12 red LEDs in the outer circle, 12 green LEDs in the inner circle and four centralized yellow LEDs. The four yellow LEDs were used to count and indicate four minutes in consecutive pattern. The inner 12 green LEDs were used in indicating […]

The machine is designed to serve with an output of 250A. it has two pats which are the primary and secondary parts. The primary part, through which voltage is supplied to the machine has 180 turns which is made of 2mm2 S.W.G 14 copper coil. The secondary part has 45 turns made of 4mm2 S.W.G 8 copper coil. Both turns are wound on separate limb of the laminated core. The voltage from primary turns flows to the secondary turn by induction […]

The project work is on the design and construction of automatic two lane traffic light control. This system is based on digital electronics. It employs an astable multivibrator which is the clock generator that sends the clock into a time sequencing generator using a decade counter with ten (10) decodes output that has it’s binary corded decimal (BCD) output into a diode or gate that sends logical data’s into a transistor switching cir […]
