EcoSwitch Circuit
The EcoSwitch circuit consists of an ESP32 microcontroller, a DTH22 temperature and humidity sensor, a L298N motor driver, a Nema 17 stepper motor, and a 12V battery pack with 8 AA alkaline batteries. It also includes a 5V regulator, a 10 kΩ resistor, an 100 nF ceramic capacitor, and a 1uF electrolytic capacitor.
The following is the circuit diagram:
The following is the hardware pinout of the ESP32 Pins for setup:
