A simplified circuit that implements the NOR logic gate, which only outputs 1 when both inputs are o, is show at the right. The tube grids are the inputs. There is no output when both grids are ...

Upload the source code to the ESP32. Assemble the circuit on a general-purpose PCB. Fix all seven LEDs on the PCB, including ...

Toshiba is aiming at UART and SPI interfaces with three four-channel dual-supply level-translator-transceivers. "The bus ...

Of course, in real life, the output won’t really be that sharp, but it will be fast and compatible with other logic signals. In practice, you might use a Schmitt trigger to read an RC circuit or ...
