The document provides instructions for an electronics circuit project. Students are asked to build a circuit using electronic components that has a specific purpose and can fit in a bag. The circuit must have all connections beneath the surface and use plastic junctions. It should also include a secondary circuit using a relay if possible. Students must document the project with a report describing the circuit design and application, materials used, and a complete budget. Suggested ideas are provided for detecting light, humidity, temperature, or presence. Online sources for buying components and ideas for projects are also listed.

1. Hi, mates !!
Let's make a circuit !!

2. During the next sessions you will have to
make a circuit.
Not too difficult … not too simple... you know!!

3. It has to satisfy certain conditions:
1.
It has to be made up of electronic
components

4. 2. It must have a purpose
3. It has to be mounted on a platform
small enough to be kept in a bag,
together with
the rest of the
components
from one
session to next
one.

5. Every connection has to be made
bellow the surface, so the upper part
has to be free-wires (as much as
possible)
4.

6. The connections have to be made by
using plastic juntions (“clemas”)
5.

7. If possible, use a relay to have a
secondary circuit in charge of having
some physical effect
6.

8. And, OF COURSE, the whole project
has to be perfectly documented, so
you have to include:
7.
Report, in which you have to describe
the specifications of the proyect, the
circuit and its application by using a
complete diagram, the places in which
you searched for info, the planning...
List of materials and tools
Complete estimate

9. Here you have nice ideas

10. Detecting light / darkness

11. Detecting humidity

12. Detecting changes of temperature

13. Timer and rotation inverter

14. Detecting presence

15. Interesting links and places to buy electronic
components. Some of them with catalogues in which
you can see the different products and prices

consult very nice practical ideas for your projects.
NO EXCUSES TO DO A POOR THING
