• ESP-01: This module is the brain of the operation. It acts as the Wi-Fi bridge allowing Alexa to communicate with the hardware.
• HLK-PM01: This is a power supply module that converts AC mains voltage to DC voltage suitable for powering the ESP-01 and other components.
• Resistors (R1, R3): These are used for current limiting and possibly for setting up pull-up/pull-down configurations on GPIO pins.
• D1: A diode which may be part of the power supply circuit or used for protection.
• [220V Light Bulb](220V Light Bulb): The device being controlled in this project. The project likely allows turning this bulb on and off using Alexa commands.

• Power Nets: These distribute power to necessary components. The power supply module PS1 outputs are connected to a +5V net.
• Ground Nets (GND): All components that need a common reference voltage are connected to the ground nets.
• Signal Nets:
  • Connections like GPIO pins on the ESP-01 (Q1) are connected to the appropriate circuit elements for signal communication.
  • Other nets establish communication between components like the ones connecting the ESP-01 pins (e.g., TX, RX, CH_PD).

1. Power Supply: The HLK-PM01 converts AC mains voltage to a suitable DC voltage for the ESP-01 and other components in the circuit.
2. ESP-01 Operation: The ESP-01 connects to Wi-Fi and communicates with Alexa. It receives commands and triggers the appropriate GPIO pins to control the 220V light bulb.
3. Diode and Resistor Use: The diode, such as D1, could be for protecting the circuit against voltage spikes, while resistors R1, R3 manage current and signal conditioning.

• Wi-Fi Connectivity: The ESP8266 chip on the ESP-01 module provides Wi-Fi capabilities, allowing it to connect to Wi-Fi networks and communicate over the internet or within a local network.
• GPIO Pins: The module exposes a few GPIO (General Purpose Input/Output) pins that can be used to interface with other components, sensors, or actuators. In this case, GPIO 0 and GPIO 2 are available.
• Serial Communication: The module has TX (transmit) and RX (receive) pins for serial communication, typically used for programming and communication with other microcontrollers or PCs.
• Power Management: The ESP8266 requires a stable power supply of 3.3V, which is taken care of by the provided voltage inputs.
• Onboard Programming: The module can be programmed using the Arduino IDE to handle specific tasks, such as sending data to cloud services, controlling devices via an app, or interfacing with other hardware components wirelessly.

• Conversion of AC to DC Power: It takes an AC input from the mains and outputs a DC voltage.

• Pin 1 (AC/L): This is the live input for the AC mains voltage.
• Pin 2 (AC/N): This is the neutral input for the AC mains voltage.
• Pin 3 (-Vout): This is the negative output for the converted DC voltage.
• Pin 4 (+Vout): This is the positive output for the converted DC voltage.

• AC Input:
  • Connects PS1:AC/L to 220 V Main:Cathode
  • Connects PS1:AC/N to 220 V Main:Anode
• DC Output:
  • Connects PS1: Vout to 5V:P1
