Week 5

Task for the final week

• Make the desired box using an ordered box

• Solder all the components and place them in

The plan to 3D print the design was dropped out. Instead a box was ordered and holes were drilled. Six holes were made on the side of the box for the LEDs and the lid of the box was cut in half. An acrylic board was laser cut(shown in the figure below) and placed in the half. The one half is for the two power supplies. The other half is for the Arduino and the circuit. The motor and the water tank are placed outside.

Fig. 5.0

 In Fig 5.0, two holes are for the wires from the power supply to go through to the next compartment. The big hole is where the USB port of the Arduino will be placed. If the user wants to change the code for the Arduino he/she can do so by inserting a USB cable through that hole.

Fig. 5.1

 Fig 5.1 shows the back side of the box. The two big holes are for the switch for the power supplies. The user can just flick the two switches ON/OFF whenever they feel the need to. It is usually always kept on since the work is automatic.

Fig. 5.2

Fig 5.2 shows the interior layout of the box when the compartment is added. The hole in the middle is for the Arduino port. The small two holes at the bottom is not seen because of its small size.

Fig. 5.3

 Fig 5.3 shows how the design would look like externally. The six holes for the LEDs are placed on the side. Theres one LED placed outside, that is how the other LEDs would be placed like.

Fig. 5.4

Figure 5.4 shows the backside of the veroboard where the components and the wires are soldered. 

Fig 5.5

The final picture shows all the soldered components and how the LEDs would be arranged outside the designed box.
