Thank you for the video! Looks like we need different location of grounding points not only because of components location. But I expect that we also better separate from each other clean and dirty ground. As we would like to protect devise from influencing one to another by the electrical noise.
Would be nice if you use a mouse-point with some highlights. Otherwise, it is not very visible when it jumps from the picture with light colours to the picture with dark colours.
Please explain once more time - why we will read 0V if we measure correctly functioning circuit between the PLUS on battery and MINUS of the solenoid in your circuit?
