Heater Controller Using UAA2016

The UAA2016 is designed to drive triacs with the Zero Voltage technique which allows RFI-free power regulation of resistive loads. Operating directly on the AC power line, its main application is the precision regulation of electrical heating systems such as panel heaters or irons. A built-in digital sawtooth waveform permits proportional temperature regulation action over a +/-1°C band around the

Sound Activated/Clap Switch Using SMD Components

Clap switch/Sound-activated switch designed around op-amp, flip-flop and popular 555 IC. Switch avoids false triggering by using 2-clap sound. Clapping sound is received by a microphone,  the microphone changes the sound wave to electrical wave, which is further amplified by op-amp. 555 timer IC acts as mono=stable multi-vibrator then flip-flop changes the state of output relay on every two-clap sound.
