Description:
This project is a simple RDS decoder based on TDA7330B RDS demodulator and AVRÂ controller. The program shows service name, RDS clock, TA flag status and scrolling 64 characters long radio text on a 2*16 line LCD. The decoder needs […]
Introduction:
Calculates and displays L and C from resonant frequency using reference components. This instrument requires A precision capacitor or a precision inductor. You only need to connect one precision component, either the reference capacitor or the reference inductor, and using this meter, you can select or adjust the other precision component.
Micro controller:
AT 90S2313
Basic Theory:
An LC […]
