Design and Construction of Avr Base Rc Meter
MetadataShow full item record
Here we make a design and installation process of the RC measuring system. First of all according to the collected information about RC measuring then total circuit design has been completed using Proteus software. A RC meter Resistance (R) and Capacitance (C) is a piece of electronic test equipment used to measure the resistance and capacitance of a component. In Electronics, capacitance is the ability of a body to hold an electrical charge Background. AVR ATMEGA8A-PU Microcontroller was programmed with programming language C in code vision AVR compiler. Microcontroller calculating this value transmitted it to a LCD to display the Resistance (R) and Capacitance (C). JHD 162D Liquid crystal display (LCD) is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals (LCD).They are usually more compact, lightweight, portable, less expensive, more reliable, and easier on the eyes. This is a basic 16 character by 2 line display with a snazzy green background with white characters. 9 V Transformer is used as its main power supply. In this transformer primary voltage is 220 V and in secondary coil voltage is 9 V AC. LM7085 voltage converter used to convert voltage (9 V to 5 V). A switch is used to start the system.
