Based on the provided components and the nets described, I can see that your project uses a NodeMCU ESP8266 module along with switches, resistors, and a buzzer. Here are a few observations and suggestions to help round out your circuit design:
  1. Decoupling Capacitors: It is a good practice to add decoupling capacitors to the power supply pins of the ESP8266 for stable operation. Typically, a 0.1µF ceramic capacitor and a 10µF electrolytic capacitor placed close to the power pins (3V3 and GND) would help filter noise.
  2. Pull-up Resistor for Reset: The RST pin of the ESP8266 should be pulled up to 3V3 using a 10kΩ resistor to ensure it doesn’t float.
  3. Stable Power Supply: Ensure that you have a stable 3.3V power supply for the ESP8266. If you supply 5V to VIN, the onboard regulator should provide the required 3.3V.
  4. GPIO Protection: It may be beneficial to include series resistors on the GPIO lines used for switches to protect against accidental shorts or excessive current.
  5. Mode Selection: For proper IoT device operation and to avoid boot issues, pins GPIO0 ($D3$), GPIO2 ($D4$), and GPIO15 ($D8$) should be configured correctly. GPIO15 should be pulled low through a 10kΩ resistor, and GPIO0 and GPIO2 should be pulled high through 10kΩ resistors.
Suggested Additions and Connections:
  1. Decoupling Capacitors:
    • Connect C1:1C1:1 to U1:3V3U1:3V3 and C1:2C1:2 to U1:GNDU1:GND (0.1µF ceramic capacitor)
