This project introduces the transistor switch and is an excellent first electronics/systems and control project for students.
The project is also excellent for GCSE students as it has been designed with KS4 curriculums in mind. It is a very versatile project and can be used as a moisture sensor, temperature sensor and light sensor. The project has been designed to allow differentiation and has space for up to 5 outputs and a range of inputs including variable resistors.
A number of different solutions are possible
Can be used with an LDR, thermistor or moisture sensor
Battery-powered
PCB has space for up to five outputs
Clear silkscreen text has been used to make construction simpler
Professional double-sided PCB pre-drilled with silkscreen and solder-resist
