Build Instructions
Before you start, take a look at the Printed Circuit Board (PCB). The components go in the side with the writing on
and the solder goes on the side with the tracks and silver pads.
Start with the resistor R1. The text on the PCB shows where R1 should go. It doesn’t matter which
way around the resistor goes into the board. Solder the resistor, remembering to trim the legs
afterward.
Repeat with R2, R3 and R4.

Checking Your Learn to Solder PCB
Check the solder joints are all good.
Is the LED correct way round?
How the Learn to Solder PCB Works
The circuit diagram for the Learn to Solder PCB is shown above. It is a very simple circuit. The 9V battery that powers
the circuit is connected via the PCB pads.
LEDs can be damaged if the current through them is not limited.
With a 9V battery, and forward voltage drop of 2.1V on the LED, a 400 Ω current limiting resistor will give a current
of 17.5mA. The LED specification is maximum current of 25mA, so the LED will light with good brightness.
The resistance has been split to give 8 solder joints to practice, rather than 2. The 4 100Ω resistors in series add up
to 400 Ω.
