Transistor Switch Project — Nightlight, Light Alarms and more...
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
-
A unique training system is available to help aid teaching and learning with this project and to help students to arrive at their final solution
-
3 versions available for maximum flexibility
-
Available with or without temperature sensor
