Description

FSR406

Tutorial: How to Use FSR406

The FSR406 is a pressure sensor ideal for human interface projects, such as touch-sensitive buttons or robot controls. Useful for beginner and intermediate makers.

What you need

• FSR406
• Arduino
• 10kΩ Resistor
• Jumper Connector

Steps

1. 1. Mount the FSR406 on a protoboard circuit.
2. 2. Connect pin A (Analog) to pin A0 of Arduino.
3. 3. Connect pin VCC to 5V of Arduino.
4. 4. Connect pin GND to GND of Arduino.
5. 5. Connect a 10kΩ resistor between pin OUT and GND.
6. 6. Load the example Sketch code.
7. 7. Test pressure by applying an object to the FSR.
8. 8. Check the datasheet for further details.

Example code

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

Mini project

Create a virtual button: connect the FSR406 to an LED, turn on the LED when pressure is applied.

Common mistakes

• Do not connect pin OUT directly to VCC.
• Ensure the 10kΩ resistor is correct.
• Make sure pin A0 is correct.
• Check the power supply voltage.

Recommended accessories

• Arduino Uno
• LED
• Variable resistors
• Jumper wire

Frequently asked questions

What is the difference between VCC and OUT pins?
VCC provides power, while OUT provides pressure reading.

Can I use an Arduino Mega?
Yes, but make sure pin A0 is compatible.

How long does the battery last?
Power consumption is low, but check the datasheet.

Can I connect more FSR406?
Yes, but connect each to a different analog pin.
