Gold award: how quick are your reactions?
In this project, students design, make and test a device to test people’s reaction times. They will need to consider the electronic circuitry involved, the power supply, input device, processor and output device. They draw a circuit diagram and make the circuitry, and could try making a printed circuit board (PCB). They might also want to make a casing for the device. Recording systems could include a pair of switches linked to a triggered cathode-ray oscilloscope, microcomputer, chart recorder or stimulus marker on a kymograph.
