Schematic Diagram and Component List

Procedures

Place and solder the 10k Ohm resistors at positions R1 through R10 on the circuit board.

Place and solder the 2.2k Ohm resistor and 10k Ohm resistor at positions R11 and R12.

Place and solder the sockets for the ICs.

Place and solder the potentiometer.

Place and solder the 1uF electrolytic capacitors at position C1 and C2, be aware of their polarity.

Place and solder the LED lights at position D1 to D10, also be aware of their polarity.

Place and solder the screw terminal block at position J1.

Insert the ICs into their adapters, there are marks on the ICs to indicate direction.

Inserting the power connector into a terminal block, be aware of the polarity. Use a screw driver to ensure a secure connection for power supply to the circuit.
