Design and Realization of Simple RCL measuring instrument
In order to solve the problems of many types of RCL measuring instruments on the market,complex operation and poor portability,a simple RCL measuring instrument design is proposed.The scheme to C51 microcontroller as a controller,through the NE555 timer will be the value of resistance,capacitance and inductance value frequency,and then by the C51 microcontroller frequency measurement,after the data processing algorithms derived from the parameters of the components under test,and displayed on the LCD1602 LCD.The results of Proteus software simulation and physical hardware test show that the simple RCL measuring instrument designed by this scheme has the advantages of high feasibility,high measurement accuracy,portability and ease of use,which can satisfy the needs of most of the measurement occasions,and has certain application value.
