atmega32 circuit

1. Abstract Wet-garden is an interactive flower garden and an ambient indoor sculpture. When people walk around it, it changes motion and LED blinking speed. Wet-design is designed for everyone who wants a tangible interaction object and an interesting...

A circuit that activates a relay upon detecting audio pulses from one channel of an MP3 player. The intention is to synchronize recorded audio pulses with music to control a motor for mouth movement. For a stereo player, music...

The timer 555 is activated by a positive trigger pulse, which results in negative output pulses. In scenarios where the duty cycle exceeds 99%, heavy loads can be disconnected from pin 7 without impacting timing accuracy, although loads exceeding...

Due to the varying conditions of different input signals, when an abnormal voltage is applied to the pin, protection circuits are established to create a circuit path from the LSI (large scale integration) circuits for internal protection. The structure...

This is an intercom circuit that utilizes the LM380 as the audio amplifier and two transistors for the microphone preamplifier. The sound quality is sufficiently good while maintaining a low construction cost. The circuit comprises two identical intercom units,...

The circuit diagram of a remote-controlled appliance switch circuit includes two main components: IC1 (NE 555) and IC2 (CD 4017). The remote-controlled appliance switch circuit is designed to allow users to control electrical appliances wirelessly. The heart of this circuit...
