LM386 Signal Amplifier | Weak Signal to Powerful Output #arduino #arduinoproject #automation
This is a simple and powerful signal amplifier circuit using the LM386 IC. An old DTH antenna captures weak signals from the air, while a copper wire coil sensor feeds them into the LM386 amplifier. Capacitors filter noise, stabilize power, and a red LED glows to indicate signal detection. Perfect project to understand signal amplification ...
