Welcome to the “Make your Own…” section of my site. These days it is quite easy to buy a specific controller or sensor from various companies online as well as from electronics shops. Sometimes it is actually preferable to manufacture your own specific part. This may seem extremely difficult and complicated to some of us, but it is actually quite easy, and you can always tailor it to your exact needs.
In this section. I will start adding some common, but extremely useful circuits for those times that you want to do it yourself, or just can’t wait for something to arrive from overseas…
This section of the site will also contain other commonly used circuit diagrams, for some commonly used shields and development boards, to be used as a reference as needed.
