Week 5 : Obtaining the required electronic component

There a list of the component that I need to buy there which shown below:

                                i.            ATMEGA328P   x 1

                              ii.            Motor Controller IC L293D x 1

                            iii.            Direct Current Motor x 2

                            iv.            Tyres of the robot x 2

                              v.            Robot Caster (will be put in front) x 1

                            vi.            Crystal 16MHz x 1

                          vii.            Capacitor 1µF x 4 (buy extra)

                        viii.            Polarise capacitor 1µF  x 4 (buy extra)

                            ix.            Resistor 10k x 4 (buy extra)

                              x.            Infrared Sensor x 3

                            xi.            Reset Button x 4 (buy extra)

                          xii.            Button x 4 (buy extra)

                        xiii.            9V battery casing

I have done some research of the very important component like ATMEGA328P, IC L293, DC motor, Tyres and Robot caster before I go buying it in the electronic store or market. That the first thing to do because I want to avoid any mistaken happen in the future. Below is the example component or part that I found it best to fit my project :

Direct Current Motor:

This Motor is very suitable for the movement of the robot and it’s more suitable for my project. It’s cheaper than the servo motor, besides servo motor I think it’s applicable in building a robotic arm. By using this, my robot movement will be more smooth because it have a double gearbox.

ATMEGA328P:

Parameter Value:

    Flash : 32 Kbytes , Pin Count: 32 , Max. Operating Frequency: 20 MHz , CPU: 8-bit AVR , number of Touch Channels: 16 , Hardware QTouch Acquisition: No , Max I/O Pins: 23 , Ext Interrupts: 24 , USB Speed: No , USB Interface: No
