Schematic circuit diagram
A schematic circuit diagram is a visual depiction of an electrical circuit. It employs universal symbols to denote elements like resistors, capacitors, diodes, transistors, among others. The lines or wires in the schematic diagram symbolize the links between these components.
Requirements:
Hardware Requirements:
+ESP32 Board: Suitable for the project.
+1.69 SPI 240x280 ST7789 Color TFT Display: To display the selected emotion.
+Six Buttons: Each associated with an emotion (joy-yellow, anger-red, love-white, disgust-green, sadness-blue).
+LEDs: Should be capable of changing color according to the selected emotion.
+Wires: To connect the components together.
+Power Source: Battery or USB power supply for the ESP32 board.
Software Requirements:
+Arduino IDE: For writing, compiling, and uploading the code to the ESP32 board.
+TFT_eSPI Library: To control the TFT display.
+WiFi Library: To send records to the server via WiFi.
+Digital Input Reading: To read values from the buttons.
+Button Input Handling: To detect button presses and trigger actions.
Restrictions:
+User-Friendly Interface: The system should be easy to use, with clear instructions and minimal complexity.
+Safety: Ensure that the hardware setup is safe to use, with no exposed wires or components that could cause harm.
+Power Consumption: Optimize power usage to ensure longer battery life if using a battery-powered setup.
+Cost: Keep the project cost-effective by using affordable components without compromising functionality.
+Reliability: Ensure the system is reliable and can operate continuously without frequent failures.
+Scalability: The system should be easy to expand or modify in the future if needed.
+Maintenance: The system should require minimal maintenance and be easy to troubleshoot and repair if issues arise.
+Environment Compatibility: Ensure that the sensors and other components are suitable for indoor use and can withstand typical indoor conditions.
