Arduino basics - solar panel

Arduino Solar Panel

Another quick & easy option for those getting started with the popular micro - Little-Scale posted a quick rundown on using a solar cell for Arduino sensory applications.

The solar panel used in this example was rated at 2V and 25mA.

Do not use a solar panel rated in excess of 5V. Doing so may damage the Arduino

If data values appear incorrect, try scaling the byte 'data' in the Arduino sketch as it is captured.

The analog inputs read data at 10 bit. However, a single, serially-printed value can only hold 8 bits of information.

The data range with this particular solar panel is 0 < 6 using power-efficient, indoor lighting at night
