timing‚ for sequential logic devices the timing or sequencing history‚ of the input signals plays a role in determining the output‚ but for combinational logic devices the output depend only on the instantaneous values of inputs. Integrated circuits (IC) are consisting of combinational logic circuits or sequential logic circuits‚ and they are considered as hardware since they are hardwired to a circuit board. Microprocessors are considered a

voltage levels are not compatible with TTL logic. Therefore‚ while connecting an RS232 to microcontroller system‚ a voltage converter is required. This converter converts the microcontroller output level to the RS232 voltage levels‚ and vice versa. IC MAX232‚ also known as line driver‚ is very commonly used for this purpose. The simplest connection between a PC and microcontroller requires a minimum of three pins‚ RxD (receiver‚ pin2)‚ TxD (transmitter‚ pin3) and ground (pin5) of the serial port

INVISIBLE BROKEN WIRE DETECTOR 1 1. INTRODUCTION In our day to day life we are dealing with electricity as well as so many electrical equipments. In this electrical equipment the household appliances play a major role. So the fault occurring with them is also a major problem. Generally the fault seen is the breaking of wire inside the two layer or three layer cables or the short circuit between them. Portable loads such as video cameras‚ halogen flood lights‚ electrical irons‚ hand drill

1. PREFACE 1.1 INTRODUCTION Radio control (often abbreviated to R/C or simply RC) is the use of radio signals to remotely control a device. The term is used frequently to refer to the control of model vehicles from a hand-held radio transmitter. Industrial‚ military‚ and scientific research organizations make [traffic] use of radio-controlled vehicles as well. A remote control vehicle is defined as any mobile device that
