Teesnsyduino Continued

Now that we have the teensyduino setup, we are going to create similar circuits but through digital logic.

The first example we will use is the push button turning on an led. There are two types of signals we deal with: analog and digital signals. Analog means that voltage can vary anywhere between ground or 5 volts. Digital signals are basically binary signals so they can only read HIGH or LOW (5 Volts or Ground). This means that if you cannot output or read something like 4 volts.
