I've been using my solderless breadboard version of my Arduino PWM Output Filter Circuit quite a lot so thought it might be useful to commit it to protoboard and build it onto a simple shield. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to … Continue reading Arduino PWM Output Filter Circuit – Part 2 →

There have been a number of occasions now where I've added a low-pass filter and voltage divider to my Arduino-based PWM outputs so I thought it was worth pulling that together into a single post to make it easy to refer to elsewhere.  This is that post.  There is nothing new here, it is just … Continue reading Arduino PWM Output Filter Circuit →
