Question

How do I lower the clock speed on Arduino?

Answer 1

Every Arduino has an on-board clock source, typically running at 8 MHz or 16 MHz. Most Arduinos use a quartz crystal to generate the clock signal, but some models have a ceramic resonator instead.Jun 15, 2012');})();(function(){window.jsl.dh('10','

Clock Speed

In order to speed up the clock on an Arduino, you need to insert a new crystal in to the board, which may or may not be difficult depending on your soldering skills. According to this post, the ATmega328 can be overclocked to 30Mhz, but I don't recommend it =)
