The study aimed to design and manufacture a lighting controller with remote control capabilities via Blynk application and wifi network. The controller in this study was designed and manufactured with hardware based on the use of Arduino Nano module, ESP 8266 module, and BH1750 sensor, combined with the established algorithm to fulfill the main purpose of controlling the brightness of the 220V lamps on a smartphone. Test results with incandescent, compact, and led lamps showed that these lamps can be remotely controlled anywhere with wifi network on the smartphone by the on/off method. Particularly for incandescent lamps and led lamps, it is possible to adjust the brightness on the smartphone. Dimmable range varies from 0 to 100% luminous flux of lamp. The controller also allows automatic adjustment of the brightness of lamps according to the ambient brightness to ensure the brightness stability as the preset value. In addition, there are also physical control buttons on the control board that synchronize with the virtual buttons of the Blynk app on the phone, which helps the control be more flexible, convenient, and energy-saving.
