Circuit Ideas

 

 

This is where you need to …..

 

And here is a link to a good example

 

 

Rounded Rectangle: Design Proposals AQA Says Involves the candidate in the gathering and exploration of circuits from any suitable resource. This can include material from books, data sheets and computer generated information. Candidates should sketch and draw out several circuits using the electronics signs and symbols shown in the specification. At GCSE level, AQA is not expecting candidates to design electronic circuits from first principles, but rather to select and modify existing circuits to meet their needs. This will manifest itself in many ways but may involve the candidate in finding a way of interfacing a primary and secondary circuit, or changing the input and output devices, or finding a latching device, or re-designing a circuit to fit in the tube framing of a bicycle. This type of activity will give the candidate the chance to hypothesise and carry out experiments using kits, software packages and breadboards to test their theories. It will also give the candidate the opportunity to use a range of measuring instruments and candidates should be encouraged to devise tests for their circuits and record their results. The use of photography in a candidate’s design folder enhances the folder and is an excellent record of experimental work carried out with kits and breadboards. At this stage in designing, candidates should be encouraged to apply mathematical calculations and record this evidence in their design folder. Work on potential dividers, component ratings, time delays, frequency, current drain, battery life and the size, use and apply the given formulae in the specification wherever possible in their coursework.
