@copilot Check that none of the unconnected pins require pull-up or pull-down resistors to ensure proper function.

Let's review the components and their respective pins to determine if any unconnected pins might require pull-up or pull-down resistors.
Components and Their Pins ESP8266 (U2)
  1. GND: Ground
  2. IO2: Unconnected
  3. IO0: Connected to Net 5
  4. RXD: Unconnected
  5. TXD: Unconnected
  6. EN: Connected to Net 1 (typically needs pull-up to VCC)
  7. RST: Unconnected (typically needs a pull-up to VCC)
  8. VCC: Connected to Net 1
MOC3021 (U1)
  1. ANODE: Connected to Net 4
  2. CATHODE: Connected to Net 3
  3. MAIN_TERM (1): Connected to Net 9
  4. MAIN_TERM (2): Connected to Net 6
BT136-600E,127 (Q1)
  1. 1: Connected to Net 10
  2. 2: Connected to Net 7
  3. 3: Connected to Net 8
Recommendations
  1. ESP8266 (U2)
    • IO2 and RST usually require pull-up resistors:
      • IO2: To ensure it remains in a stable state during startup, adding a pull-up resistor to VCC is advisable.
      • RXD, TXD usually do not need pull-ups/downs for communication but should be validated based on specific use case.
  2. MOC3021 (U1)
    • All pins are connected as required, so no additional pull-up/pull-down resistors are needed for proper function.
  3. BT136-600E,127 (Q1)
    • All pins are properly connected.
Would you like me to suggest specific pull-up resistor values and connections for the ESP8266 pins?
