FYP 2 Week 5

For this week, I was researching what fan should I use for my project. I plan to use DC Fan that is small and portable so that it won't be cumbersome to present on the presentation day. DC fan also easier to be programmed with Arduino compared to AC fan. I decided to use 12V DC Fan. I will be using 9V battery as the power supply and the transistor I use will amplify the power and can make the fan move even the power supply is not 12V.
