lm386

Arduino Text-to-Speech Library

Arduino based FM radio using the Nano and the modules: SSD1306 OLED , TEA5767 FM radio, LM386 audio amplifer and KA2284 Audio level..

🚗 LM555 generates a car/bike/bicycle/scooter horn sound which is amplified by LM386

LM386 based audio amplifier for raspberry pi zero

Hello World for KiCad with LM386 audio amplifier

Arduino based Ultrasonic transmitter and receiver device.

Stereo FM / AM Radio Receiver with VU Meter based on the TEA5711 radio IC and dual LM386 audio amplifiers. This project features FM stereo and AM reception, a 10-LED stereo VU meter, custom PCB design, and is intended for educational and non-commercial DIY electronics use.

This is an ESP8266 based audio transmission experiment

The Ultimate LM386 BTL Amplifier

My take on building a low-power, hybrid guitar amp

Detecting 40kHz magnetic fields using an RL810 coil with 1.1V ADC reference, signal inversion, and digital filtering on Arduino.

This is an FM clock radio with an alarm. It uses a Raspberry Pi Pico 2 W and MicroPython firmware. It has an RDA5807M tuner, an OLED, a rotary encoder and a Wi-Fi web UI. It also has a KiCad PCB that we made and a 3D-printed turtle enclosure. We made it for ECE 299 at the University of Victoria (UVic).
