is a great project for learning about four important parts of any electronic
circuit ... and after a lot of soldering .. it
works!
- Let's start by identifying the parts of the printed circuit
- Click on this picture to see the enlarge photo of the circuit
- Try and identify the holes that are marked D, R, C, and Q .. the
numbers alongside each letter will identify separate components.
For example D9 and D10 are the same bit .. but duplicates in
different parts of the circuit.
- Now insert the
parts
|
 |
- The actual circuit board is now linked to a symbolic circuit ...
this will show how the electronic components are attached ...
|
 |
- See if you can work out what the parts D, R, C and Q do on our
LED Tree!
