1 Partaking in regular exercise can improve skin elasticity. 2  It is recommended to have 30 minutes of aerobic exercise to improve circulation for the skin. 3  This gives the benefit of feeding the skin and removing any waste products more effectively. 4  Hence, you will have a more youthful skin.

Note that these are Arduino pin numbers, and do not correspond to the physical pin numbers on the Atmega168 chip. The analog pins can be used identically to the digital pins, so for example, to set analog pin 0 to an output, and to set it HIGH, the code would look like this:
Yes, the analog pins on the Arduino can be used as digital outputs. This is documented in the Arduino input pins documentation, in the Pin Mapping section: Pin mapping. The analog pins can be used identically to the digital pins, using the aliases A0 (for analog input 0), A1, etc. For example, the code would look like this to set analog pin 0 to an output, and to set it HIGH:
