Instruction Manual for Soldering Kit
1. For this activity, you will require the following components:
2. Hold the PCB in your hand like this.
3. Take a closer look at the PCB (Printed Circuit Board), notice the labels on the PCB, these will guide you to
insert the required component in the designated slot.
4. Insert he LED in the LED slot as shown, insert the longer leg in the hole that has the + sign and the smaller leg
in the – sign.
5. Now flip the PCB and immediately solder the legs on the board. If you are having any problems with the LED
falling off the PCB, you tape it on the surface of PCB, Warning: Do not try to keep the PCB and LED together
while soldering as it is extremely hot so use a tape to keep them in place. Warning: While soldering take
extreme care that the solder wire doesn’t touch the other leg of the LED (The two wires shouldn’t touch
each other and there is no connection between them otherwise there will be a short circuit and the Circuit
won’t work).

6. Now Insert the Transistor as shown in the picture, make sure the D shape of transistor aligns with the D
outline on the PCB.
7. Now solder the 3 legs of the Transistor on the PCB and make sure none of the 3 legs are soldered to each
other.
8. Now insert the LDR on PCB as shown. LDR slot is labeled on the PCB.
9. Now solder the legs of the LDR on the Board and take precaution that both the legs should be separately
soldered on the board and there should be no connection between them.
10. Read the Color code on the resistances provided and take out a 560-ohm resistance and insert it in the R1
slot as shown. (to read the color code refer “How to read the color code of a resistance” Manual from the
Resource section on LearnOBots Website)
11. Solder the Legs of the Resistance.
The LDR will become
extremely hot and might
Burnout if you solder its legs
too much so take care and
don’t solder too much
12. Read the color code and insert a 56 kilo Ohm (56,000) resistance in the R2 slot as shown. Repeat the process
of soldering for this resistance as well.
13. Now connect the Battery connector to PCB, connect the Red wire to the V slot and black wire to GND slot.
14. Solder the two wires on the board by flipping the board
and take the same precaution of keeping the two solders
separate from each other.
15. Now connect the battery to the battery connector as shown.
16. The circuit is complete now and the LED will light up in dark and will shut down when exposed to light.
