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.

1.Using Tinkercad : Create and program with Arduino - Traffic Light and Knight Rider strobe

(0)
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.
