In the example Battery level, when using the scope on the 3 components of a same branch: - sum of voltages are different of the main voltage (because zener values are negative) - when reducing main voltage current values become different Many different pinouts exists for BJT and MOSFET transistors and there is no indication about their reference or pinouts. If it is the most common layout that is used, it would be nice to refer to it in the description (CBE for NPN, EBC for PNP and SDG for MOSFET). Else the scope is very minimalist. No way to adjust the display, no graduations to measure periods and so on. Else thanks for your very great job ;)
