Bought to my attention by programming luminary Andy Cordani, was something he spotted here at Hackaday, which is a very nice application of multiplexing and matrix maths to determine the value of ...

Many times, the need arises to interface single-supply analog-to-digital converters (ADCs) and comparators to real-world signals like 5 V. Of course, it's possible to condition the signal using ...

The following resistor network is set up. Calculate the total resistance of the network. This means that the three individual resistors can be replaced by one resistor of \({3.27}\Omega\). Adding ...
