Remote Controlled FAN Control System


Fan Speed regulator using Clapping sound and other logic inputs.


Using ladder logic to toggle states and drive 5 relays for 6 speed
fan control.
Using the the D Flipflops(7474) in counter arrangement to count the
pulses and activate a relay at a time.

The spike of a clap sound trigger the counter. It was also linked to
The Smart Home control devive to switch the device remotely.
