These are some of the Circuit Diagrams and Logic Gate Work we did in class.
On the left is the diagram of an Arithmetic Logic unit. According to the switch position the circuit acts as an X-OR or an AND gate and the corresponding outcome is outputted by the LED
Above are two circuits we made while working with NPN and PNP Transistors.
Below is a diagram of a circuit we had to build with a buffer chip and the final product.
