Project Progression

Obtaining Materials

After completing the initial design of the circuit, the next thing is to obtain the components needed in the circuit. During the CNY holiday period, group member Lim Chun Yap had bought LEDs, wires, veroboard, IC 74LS86, two-pole switch and solder at Ipoh. On the 7th of February, Lim Chun Yap and Lucerne went to Jalan Pasar to puchase resistors, capacitors, transistor and battery. All materials are prepared and ready to be fitted into the veroboard.

Fixing Components

The process of putting all the components onto the veroboard based on the circuit diagram was done by me. After 2 hours of hard work, all the components had been put in place in the veroboard and are ready to be soldered. Electrical and Electronic(EE) Lab was borrowed to do the soldering. Most soldering was done by me with the help of group members. Eventually, the soldered design was completed.
