Below is a schematic change suggestion for your Smart Plant Pot project:
Add a 5V Power Source:
Component: 5V DC Power Supply (Note: If you don't already have a generic power source symbol, you may create a custom part named “5V Power Supply” with designator [V1].)
SDA: Connect to [ESP32-DEVKIT-V1] pin D21 (GPIO21)
SCL: Connect to [ESP32-DEVKIT-V1] pin D22 (GPIO22)
I2C Pull-up Resistors:
Add a 4.7kΩ resistor (e.g., R1) between SDA and 5V
Add a 4.7kΩ resistor (e.g., R2) between SCL and 5V
Common Ground:
Ensure all components sharing GND (including the 5V power source, ESP32-DEVKIT-V1, MAX6675, DHT22, and the OLED display) are interconnected to the Ground component.
You can use “Apply changes” to incorporate these updates into your schematic. Let me know if you’d like to modify or add any further details!
