The screen of NandGame looks like this. We will install a NAND gate on the purple board and build a new circuit. The explanation of the circuit to be assembled is written on the left. The language can ...

Using just two NAND or inverter gates its possible to build a D type (or ‘toggle’) flip-flop with a push-button input. At power-up the output of gate N2 is at a logical ‘1’, ensuring that transistor T2 ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...
