Brief Description
Soldering and contructing a functional light sensor




Students receive electronic parts, soldering tools. Their task is to plan and construct a light sensor that switches on during low light.

Educational subject: technology

Duration: one lesson (45 min)

Target group: gymnasium

Students age: 16-17 years

Context of professional activity: specialties related to electronics installation, maintenance equipment

Students are introduced to the task, giving them the details of the electronics, which they will need to properly thaw, so that the bulb will turn into darkness.

Task for students

Imagine being an electronics specialist. You need to install electronic part so that just after dark a light sensor mounted react and turn on the light bulb.


The measures are based on the students' ability to recognize the details of the electronics and how they are combined. For more advanced students, it is possible to give more electrician details so that students can independently decide what resources they need.

Parts and accessories required for the installation of a light sensor:

• soldering station

• Soldering with rosin

• mounting plate

• resistors

• current source

• connecting cables

• bulb

• item

• diodes

• converters

• photo resistor

• potentiometer

• capacitor

• thermistors
