Resources for GCSE Computing course for the Data Representation topic. The Resource explains how different data is stored, so introducing data types and variables and shows how important it is to make sure the correct variables are selected by the programmer. Uses examples in Python and an excel program ( input form and vba coding) has been created for students to investigate for themselves, what can go if wrong data types for variables are chosen by the programmer. Overflow error, type Mismatch, rounding up errors, Validation etc.

Resource shows how to build a circuit with leds, distance sensor and a buzzer using a breadboard and how to program using Arduino. Explains how distance ultrasound is used to measure distances in introduces a sequence of if statements to create a reverse parking sensor which uses sequence of lights and alternating tones from a buzzer to simulate a parking sensor using Tinkercad. Introduces for loops to control brightness of an led and changing the tone of a buzzer. Explains how Square waves can be used to output analogue data. Used for year 9 to make coding more engaging in preparation for choosing Computer Science at GCSE.

A tutorial ( part 1 &2) showing how to use Tikercad to create circuits and program with the Arduino Microcontroller. A fun introduction to programming can be used for Year 8 to 11 learners. Used to practise circuit bulding and programming before building their own circuits using leds, breadboard and Arduino connected via usb to their computer. Used with Year 9 to introduce electronics and programming. Lesson 1 : Controlling an led Lesson 2 : Creating a Traffic Light Simulation. Lesson 3 : Creating a strobe light effect - Knight Rider car Tinkercad is great simulation program , students learn quickly and then are much more confident at to being able to take the exported code and build their own circuits. Makes it much easier to manage a class of 25 Year 9s all doing practical.
