Control of LED using BOLT Wi-Fi Module through Bubble web app over Internet

This paper presents an economical and reliable solution for LED control by utilizing the Bolt Wi-Fi module through a Bubble web app integrated with the Internet of Things (IoT), eliminating the need for programming skills. Leveraging a User Interface (UI) builder, Application Programming Interface (API), and the Bolt Wi-Fi module ESP 8266MOD (ISM-2.4GHz, PA +25dBm, 802.11b/g/n) operating at 2.4 GHz frequency, LED control is achieved. The paper introduces a block control system for LED ON and LED OFF, allowing users to select appearance styles - a success button for LED ON and a danger button for LED OFF. Digital wire plugins are employed for both LED states, utilizing pin zero with a high status for LED ON and low for LED OFF.
