Today I decided to muck around with my Arduino Nano. I plan on utilizing it with ham radio projects. The Nano comes with a basic program that makes an LED blink. Kind of like a self test. The program starts as soon as the Nano is plugged in. While staring at the light I thought about hooking up the Nano to my oscilloscope. The scope is brand new to me and I thought it would be an opportunity to twist a few knobs and push a few buttons. Watching the Nano blinking along side the o’scope made me think it was a good visual how the o’scope takes a dynamic signal and portrays statically.
An o’scope takes a snapshot of a moment in time. It measures voltage over time which is why the blinking light was a good example. The o’scope shows power coming on and then one second later, going off. For this sinple example we can answer the following questions: Does the Nano output full voltage? Does the Nano switch states or “blinks” at the proper interval. Is the Nano consistant (blinks approx. at the right time and at the right voltage)? There are a lot of tools and techniques not covered in this short post. I wanted to share a simple discovery about what an o’scope can do without a lot of technical stuff , just a little fun. 73 – Scott

I used scopes in the military. there are some really good ones around now.
