Project #242
OBJECTIVE: To make a complete working AM radio.
When you turn on the slide
switch (S1), the integrated
circuit (U5) should amplify and
detect the AM radio waves all
around you. The variable
capacitor (CV) can be tuned
to the desirable station.
Varying the adjustable resistor
(RV) will make the audio
louder or softer. The power
amplifier IC (U4) drives the
speaker (SP) to complete the
AM radio project.
