Automatic Broadcast Transmission Control With 8 Relay Channels Based On Arduino

Abstract

Abstract This Automatic broadcast transmission control is a device that functions to replace a manual switch to an automatic switch with a programmed starting timing process. This device consists of an LED VU Display as an indicator of the voice signal input, a monostable multivibrator as a timer, an Arduino Uno as the main control, and an 8 channel relay module as a substitute for a manual switch. This tool works when the voice signal is active, then relays 1 to 8 will be active, but if the voice signal is off, relays 8 to 1 will be deactivated gradually. On off this channel relay is determined by programmed timing. The results of the experiment show that the active and non-active time of the relay can be programmed in stages with a time difference of 1 second for each relay. Automatic Transmission Control with 8 Relays using Arduino Control is able to automate switching from manual switching to programmable automatic switching.
