1. Connect the VCC pin of the HC-SR04 to the 3V3 pin on the NodeMCU (Designator 3V3). This will provide the power to the HC-SR04.
2. Connect the GND pin of the HC-SR04 to the GND pin on the NodeMCU (Designator GND). This will establish a common ground between the sensor and the microcontroller.
3. Connect the TRIG pin of the HC-SR04 to one GPIO pin on the NodeMCU. Usually, any of the D0 - D8 pins can be used. Let's say we are using D2 GPIO4 (Designator D2 GPIO4 SDA). This pin will be used to send the signal from the microcontroller to trigger the sensor to take a reading.
4. Connect the ECHO pin of the HC-SR04 to another GPIO pin on the NodeMCU. Let's say we are using D1 GPIO5 (Designator D1 GPIO5 SCL). This pin will be used to receive the signal back from the sensor.

   • Group components whose values are within ±50% of each other.
   • Ensure they share the same package code and type.
3. MPN Analysis: For each group, we'll need to check the MPNs for compatibility in terms of electrical and mechanical specifications.
4. Cross-Referencing: We will cross-reference these components to find an MPN that can replace the existing ones without affecting performance.

1. Connect Your Input Device: This could be a button, switch, or any digital sensor.
   • Connect one terminal of the button to D3 GPIO0: Connect your_input_device:output to D3:GPIO0.
   • Connect the other terminal of the button to GND: Connect your_input_device:other_terminal to GND.
2. Configure Pull-up Resistor (if necessary): If you're using a button or switch, it's a good idea to use the internal pull-up resistor to keep the input HIGH when the button is not pressed.
   • Enable the internal pull-up resistor in your code (this will depend on the development environment you're using).
3. Read the Pin in Your Code: Check the state of D3 GPIO0 to determine whether the button is pressed or not.

1. Connect Your Analog Sensor: Connect the output of the analog sensor to A0.
   • Connect your_analog_sensor:output to A0.
2. Read the Pin in Your Code: Use the ADC function in your development environment to read the analog value from A0.

Cpp
void setup() {
  pinMode(0, INPUT_PULLUP); // D3 GPIO0 as input with pull-up resistor
  Serial.begin(115200);
}

void loop() {
  int digitalValue = digitalRead(0); // Read digital input from D3 GPIO0
  
  int analogValue = analogRead(A0); // Read analog input from A0
  
  // Print the values to the Serial Monitor
  Serial.print("Digital Value: ");
  Serial.print(digitalValue);
  Serial.print(", Analog Value: ");
  Serial.println(analogValue);

• Safety: Ensure you're using an appropriate current-limited power supply to avoid damaging your board.
• Compatibility: Confirm the voltage levels are within the board's specifications to prevent overvoltage.
• Verification: Any issues in the above tests may require checking board schematics or connections for faults.

1. Reference Point for Voltages: It acts as a reference point against which all other voltages are measured within the circuit. Without a common ground, it would be difficult to establish the voltage levels of different parts of the circuit relative to each other.
2. Return Path for Current: It provides a pathway for electrical current to return to its source after passing through the circuit's components. This ensures that the circuit is complete, allowing devices to function correctly.
3. Stability and Noise Reduction: By providing a common ground, it helps stabilize voltage levels across the circuit and reduce electrical noise. This is crucial for sensitive electronic components and circuits, like those in your NodeMCU ESP8266, to function accurately and reliably.
4. Safety: In larger electrical systems, grounding helps protect the system and users from electrical faults by providing a safe pathway for fault current to disperse, reducing the risk of electrical shock.
