Features

• 2 Phillips M3 screws
• Used to build multi-purpose distance sensors

What it is for

Phillips M3 screws are useful for distance and proximity measurement projects, ideal for beginners and intermediates. They are compatible with Arduino and can be used to build simple distance-based alarm systems.

Tutorial: How to use Phillips M3 screws

These pieces are useful for building multi-purpose distance sensors, ideal for beginner and intermediate Arduino projects.

What you need

• 2 Phillips M3 screws
• Arduino
• 10kΩ resistor
• Power cable

Steps

1. 1. Prepare the necessary components.
2. 2. Connect the Phillips M3 screws to pin A0 of the Arduino.
3. 3. Connect the 10kΩ resistor between the VCC and GND pins of Arduino.
4. 4. Connect the resistor between the VCC pin and the M3 Butterfly Dado.
5. 5. Connect the GND of Arduino to the M3 Butterfly Dado.
6. 6. Load the following code onto Arduino.
7. 7. Check if the value read from A0 varies with distance.
8. 8. Check the datasheet for further details.

Example code

```
void setup() {}
void loop() {
  int value = analogRead(A0);
  Serial.println(value);
}
```

Mini project

Build a simple distance alarm system.

Common mistakes

• Do not connect the M3 Butterfly Dado correctly.
• Omit the 10kΩ resistor.
• Do not use the A0 pin.
• Power the M3 Butterfly Dado directly without a resistor.

Recommended accessories
