arduino Electret Microphone preamplification will it work for dynamic type microphone

The circuit functions adequately, although it is not ideal in terms of quality. However, there is a minor issue when interfacing the output with an Arduino. The output swings below ground, meaning it is biased at 0V, while the Arduino's...

Honey Bee Counter Circuit

A real-time clock turns off the counter at night to conserve power. When a bee crosses under the LED, the light is reflected back to the sensor, which is a phototransistor, and triggers a digital input to the Arduino (or...
