Testing DICM system

The DICM system has been tested on iron. The following picture shows the result of this DICM system without use the real crops. It is just to test the function of each sensor that used and each component used on this DICM system either function or not .

~ At the beginning,

~ Forward,

~ Once this DICM system detect the crops,

 process mode means that this DICM system is fertilizer and pesticide the crops

~ Once this DICM system detect the obstacle in front of this DICM system,

This command shows that this DICM system detect the obstacle. Obstacles in this system shows it has two

obstacles which are human or animal in front of this system and another obstacles is this system is reached at the end of the iron. If this system reached at the end of the iron, another command which is "Hold red switch" will display to notify the user to hold the red switch and lastly this system will be reversed  

~ Once the red switch was pressed, 

When in "reverse mode", this system will reverse back at to beginning until the switch was pressed and this system will automatically off.

Make the mechanical parts

The purpose of this mechanical parts is shows how this DICM system moves on the rod of iron. This mechanical parts have been made in Sekyen 17, Shah Alam. Picture below shows the process to make the mechanical parts. 

The workshop map:

Design of mechanical parts:

Making mechanical parts process: 

~ Measuring

~ Cutting

~ Drilling 

~ Soldering 

~ Complete mechanical parts

By doing this mechanical parts, the DICM system is ready to testing on this iron. 

Assemble DICM circuit in the boxes

This procedure is important to protect the circuit from damage. Besides that, it will protect all the electronic components and wire's from heat and water and in addition, it will be used to placing the DC gear motor on the top and placing the water sprinkler tank at the side of boxes.  The assembling DICM circuit in the boxes process are shown in picture below:

* Tools and equipment used:

~ Screw driver

~ Test pen

~ Long nose

~ Soldering iron 

~ screw (set)

Assemble the components

Below are the some of components used for this DICM system:
~ Solenoid motor 12V
~ DC gear motor 12V
~ DC motor for water sprinkler 12V
~ Liquid Crystal Display (LCD)
~ IR sensor
~ Buzzer 
~ IC driver motor
~ Power transistor 
~ Crystal
~ Resistor
~ Capacitor
~ Diode
~ etc 

Picture below show the components that used in this DICM system:

Drilling and troubleshooting

To complete the PCB process, the circuit board was fixed to a piece of wood or box. The holes on the circuit board was drilled (holes should be at least 0.1mm bigger than pins or wires) by using Pro'skit drill set. The drilling process is shown in figure below.

After complete drill the holes, the connection between the tracks must be checked and troubleshoot by using multimeter. It is useful to know the tracks is connect to each other or not. If there are no connection between the tracks, the jumper wire can be used to solve the problem. The checking and troubleshoot process is shown in figure below.
