This project demonstrates a simple embedded system that uses a touch sensor to control an LED. The code is written in Embedded C for an Arduino Uno and compiled using the Arduino IDE. When the touch sensor is activated, the LED connected to pin D13 lights up.
- Detects input from a touch sensor connected to pin D10.
- Turns on an LED connected to pin D13 when the touch sensor is activated.
- Uses minimal resources for reliable performance.
- Hardware:
- Arduino Uno
- Touch sensor module
- LED
- Resistors (if required)
- Connecting wires
- Software:
- Arduino IDE or AVR-GCC toolchain
| Pin | Function |
|---|---|
| PB5 | Output to LED (D13) |
| PB2 | Input from Touch Sensor (D10) |
touch_led.ino: Source code for the project.
- The
touch_led.inoprogram configures pin D13 (PB5) as an output for the LED and pin D10 (PB2) as an input for the touch sensor. - The program continuously checks the state of the touch sensor input.
- If the sensor sends a HIGH signal, the LED turns on.
- If the sensor sends a LOW signal, the LED turns off.
-
Hardware Setup:
- Connect the LED’s anode (long leg) to pin D13 and the cathode (short leg) to GND through a resistor (220 Ω recommended).
- Connect the touch sensor output to pin D10.
- Ensure the touch sensor is powered appropriately.
-
Software Setup:
- Open
touch_led.inoin the Arduino IDE. - Select the correct board (Arduino Uno) and port.
- Upload the code to the Arduino Uno.
- Open
-
Run the System:
- Activate the touch sensor to observe the LED turning on and off accordingly.
- Ensure the touch sensor module provides a stable HIGH signal when activated.
- The code assumes no external pull-up/pull-down resistors are needed; use internal pull-ups if necessary.
