Step 3: Soldering components

Now it's time to solder components on the board. Here is a good instructable for Soldering.

1. Solder the mouse IR transmitter and receiver on the board.
2. Solder 470ohm resistor behind the IR transmitter.
3. Solder 10k resistors on the board.
4. Solder some wires on the lines that connect two holes together. (jumpers)
5. Solder microcontroller socket on the board in a correct direction.
6. Solder seven segments.
7. Solder transistors.
8. Solder buttons with some wire.
9. Solder the capacitor on the board in a correct direction.
10. At last solder the switch to the battery holder and solder its wires to the BAT terminal.
