| + | ===== Demo ==== | ||
| + | |||
| + | In the demo, the main page of the web app will be showcased, featuring the date pickers that allow users to select a specific time range for data visualization. To illustrate the control system, a light bulb will be connected to the relay by connecting the positive terminal of the outlet to the positive terminal of the bulb. We will be able to switch the relay on or off, thereby controlling the power supply to the light bulb in real-time. | ||

By accident, I connected the bulb to the current outlet relay instead of connecting it to the designated light relay, but you still can see the functionality. | ||
