RANCANG BANGUN SISTEM KONTROL PEMUTAR ANTENA YAGI BERBASIS MIKROKONTROLER DALAM MENGATUR ARAH PENERIMAAN SINYAL TELEVISI

Television generally requires an antenna to capture. The commonly used is the Yagiantenna. This type of antenna needs to be rotated to adjust the direction of signal reception toimprove image and sound quality. In this design, users simply need to press a button integratedinto two systems: a wireless system for remote control and a push-button system for close-rangecontrol. These systems adjust the antenna's position to the right or left, according to the directionof the desired signal. The push-button system features five push buttons as inputs, which respondto pre-programmed commands, and the wireless system requires pin initialization connected tothe ESP32, which links to the Blynk application and the Internet. Blynk displays the current anglesensor measurements uploaded to the database by the ESP32. Testing of the push-button controlsystem showed a consistent match between the antenna mast's angle rotation on the LCD displayand the physical degree arc, with an average error rate of 0.74%. Testing of the wireless controlsystem using the Blynk application with IoT concepts also demonstrated consistency between thetest results of the wireless control circuit and the antenna mast's angle rotation, with an averageerror rate of 0.73%.
