The signal generator is part of a series of electronics tutorials. In this one I explain a bit about waves and after you go through the tutorial, you can try out my signal generator. Look for the next tutorial in the series which is in the planning stages now. There we will be looking at a machine called an oscilloscope (scope for short) that lets us view waves. After that look for a tutorial on building your own simple audio amplifier. This tutorial will build on the first two tutorials and uses both electronic test instruments that you will have learned about in the first two tutorials. Watch for the tutorials in the near future. Have fun scratching!
