FAQ
Welcome to the FAQ page for the Arduino Explorer: 30 Days, 30 Sensors project!
Here you'll find answers to common questions and troubleshooting tips to help you on your sensor journey.
Q: Do I need prior experience with Arduino to start this challenge?
A: No, this challenge is designed for beginners and guides you step-by-step through each sensor.
Q: What Arduino board do I need?
A: We use the Arduino Nano for all projects, but many tutorials also work with Arduino Uno or similar boards.
Q: Can I use a simulator if I don’t have hardware?
A: Yes! You can use platforms like Tinkercad to simulate circuits virtually.
Q: How do I connect the IR Obstacle Sensor correctly?
A: Check the wiring section in each tutorial. Typically, VCC → 5V, GND → GND, OUT → digital input pin (e.g., D2).
Q: My sensor output is always HIGH/LOW, what should I check?
A: Verify wiring connections and power supply. Also, make sure the sensor is compatible with your Arduino voltage.
Q: What Arduino IDE version should I use?
A: Use the latest stable version of the Arduino IDE, available at arduino.cc.
Q: I get errors uploading the code, what can I do?
A: Ensure the correct board and COM port are selected under Tools in the Arduino IDE. Check drivers if necessary.
Q: The onboard LED never lights up when testing the IR sensor.
A: Make sure your code logic matches the sensor’s output signal (LOW means obstacle detected). Try adding serial prints to debug.
Q: Serial Monitor shows no output.
A: Confirm Serial.begin(9600) is in setup() and Serial Monitor baud rate is set to 9600.
Q: Can I contribute tutorials or improvements?
A: Absolutely! Open issues or pull requests on GitHub. We welcome community contributions.
Q: Where can I ask for help?
A: Use GitHub Issues or Discussions in the repository. You can also contact the maintainer via LinkedIn or email.
