The Logic and Arithmetic kit incorporates core electronics concepts suitable for A-level Computer Science students, in particular covering aspects of Boolean operations, logic gates and base 2 (binary) number systems.
The kit is split into two sections: ‘Logic’ and ‘Arithmetic’, with Light Emitting Diodes (LEDs) used to indicate logic states throughout.
This kit is currently undergoing the final stages of development and testing. Please contact us if you are interested in using it.
This can be used to explore Boolean operations and logic gates, and to implement simple logic functions and circuits. The board has three switchable logic inputs, a range of different logic gates (AND, OR, NAND, NOR, XOR, NOT), and three logic outputs. Orange LEDs indicate the state (logic 0 or 1) of the individual inputs and outputs of every gate.
This provides an 8-bit two’s complement adder/subtractor circuit, offering the ability to perform A+B or A-B (where A and B are 8-bit binary numbers). This can be used to experiment with unsigned and signed binary arithmetic, as well as offering a different way to observe and understand binary number systems. This can even be extended to a 9-bit adder circuit, by using the Logic Section of the kit to implement a Full Adder.
