Analog acquisition tools are super helpful whenever you want to run an experiment, test out a theory, or improve upon your code, and you won’t realize how much you always …read more Continue reading Add the Analog Toolkit to Your…Toolkit
One of the first frustrating situations a beginning microcontroller programmer will come across is the issue of debouncing switches. Microcontrollers are faster than switches, and the switch has yet to be built that can change state in zero time like they can on paper. This hurdle is easily overcome, but soon we are all faced with another issue: filtering noise from an analog signal. Luckily [Paul Martinsen] has put together a primer of three different ways to use an Arduino to filter signals.
The first (and fastest, simplest, etc.) way to filter an analog signal is to sample a bunch …read more
