![]() ![]() Two 1000pF capacitors are styroflex 1% and inductor is 82uH. ![]() Following the above link you will find the original schematic, PCB, source and HEX files for programing the microcontroller and detailed description.Here is my adaptation of the schematic:I removed the 7805 regulator, because I decided to use a 5V adapter from Sony mobile phone.In the schematic, trimmer-potentiometer is 5k, but actually I put 10k, after consulting with the datasheet of the LCD module I bought.Īll three 10uF capacitors are tantalum and C7 – 100uF actually is 1000uF. This type of meter, especially L meter is hard to find in cheap commercial multimeters.Schematic of this one came from this web page.It uses PIC microcontroller 16F628A, and because I recently acquired a PIC programmer, I decided to test it with this project. DescriptionHere is another piece of laboratory equipment – LC meter. This project is a simple LC meter based on PIC16F682A mcu. 16f628a Simple Program Design Chapter 9. ![]()
