Taking pictures with the OV7670 camera module
In this first recipe, we will build an electronic circuit to take pictures with the OV7670 camera module, using the Arduino Nano. After assembling the circuit, we will use the pre-built CameraCaptureRawBytes sketch in the Arduino IDE to transmit the pixel values over the serial.
Getting ready
The OV7670 camera module, illustrated in the following figure, is the main ingredient required in this recipe to take pictures with the Arduino Nano:

This vision sensor is one of the most affordable for tinyML applications, as you can buy it from various electronic distributors for less than $10. Cost is not the only reason we went for this sensor, though. Other factors make this device our preferred option, such as the following:
- Low frame resolution support: Since microcontrollers have limited memory, we should consider cameras capable of...
