Common Questions about Microcontroller Hardware and Code Expert
How can I troubleshoot common connection issues with my ESP32-CAM?
Start by checking the power supply, ensuring it provides enough current (at least 5V, 2A). Next, verify the pin connections, especially GPIO0 for boot mode. Also, ensure your FTDI adapter is set to 3.3V, not 5V, when flashing.
How can I use PWM on Arduino Uno to control a motor?
Arduino Uno offers PWM on pins 3, 5, 6, 9, 10, and 11. You can use the `analogWrite(pin, value)` function to vary the motor speed by adjusting the duty cycle. Make sure the motor driver is correctly interfaced with these pins.
Can this tool help with interfacing I2C sensors on ESP32-CAM?
Yes, the ESP32-CAM supports I2C on GPIO 21 (SDA) and GPIO 22 (SCL). You can use the Wire library to interface with I2C devices like temperature or humidity sensors. Ensure proper pull-up resistors (typically 4.7kΩ) are in place.
What should I consider when connecting an external power supply to Arduino Uno?
The Arduino Uno has a barrel jack for external power. Use a supply of 7-12V DC, as it has a built-in voltage regulator. Always avoid exceeding 12V to prevent overheating the board's regulator.
How can I capture an image using ESP32-CAM and send it over Wi-Fi?
First, set up the camera using the `ESP32-CAM` library. After configuring the Wi-Fi, use the `WiFiClient` class to send the captured image data to a server or client. You can capture images using `camera_fb_t` from the camera driver.
