Happy New Year Animation
In this challenge we will use Python code to create a text-based (ASCII) animation to be used as a final countdown before the new year! Our countdown timer will be based on a for loop to count down from 5…
Little Man Computer – Max Function
In this challenge we will create a computer program using LMC (Little Man Computer) that takes two inputs and outputs the larger (max) of the two inputs. By completing this challenge we will investigate the use of the branching instructions…
Little Man Computer: Countdown Timer
In this challenge we will create a computer program using LMC (Little Man Computer) that takes a number as an input (e.g. 5) and outputs a countdown from this value. (e.g: 5.4.3.2.1.0). By completing this challenge we will investigate the…
Little Man Computer: Mini Challenges
By completing this set of 12 mini challenges you will write programs using Little Man Computer using all the instructions of the LMC instruction set (See below). You will start with basic Input / Process / Output challenges based on…
BCD to 7-Segment Display
What is BCD code? In computing and electronic systems, binary-coded decimal (BCD) is used to encode decimal numbers (base-10 numbers) in a binary form where each decimal digit is represented by a nibble (4 bits). For instance decimal number 5…
BBC micro:bit Counter using a 7-Segment Display
The aim of this challenge is to create a countdown timer, controlled by a BBC micro:bit that will display the numbers on a screen using a 7-segment display. A lot of electronic devices use this approach to display numbers on…
Logic Gates Tester Kit
The purpose of this challenge is to create an electronic circuit used to test and identify logic gates integrated circuits. Logic gates are built as integrated circuits (also referred to as chips, or microchips). An integrated circuit is a set…
