GCSE ELECTRONIC PRODUCTS
I have decided to reformat and update this page as it was difficult for me and my students to locate things quickly. There are sections for basic circuit examples, concepts, practical work such as breadboarding. These are focussed around GCSE Electronic Products course - OCR. For further progression and more able students, there are more topics on the A-LEVEL page

This page provides students and teachers with resources for . They are divided into categories and are mainly electronic theory rather than the product design and analysis aspects of the course. I have written most of them and they are free to use as and when you think appropriate. They are generally in PDF format because of file sizes. More will be added as time allows.
