This week, we were assigned to make a device that can be used at home, has two outputs, and performs a function.
so i decided to make a blower for my workshop to blow up the dust and tiny dirt I can't move.

First, I simulate the circuit on TinkerCAD to visualise and test it before wiring it.
mounting and wiring the components together.
I chose to do the circuit in parallel because the led needs a 3v to light and the fan needs at least 5v to run properly, so I connected the negative of the led with a 220 resistor to get 3v from the five volt adaptor and the positive from the fan to the positive relay. In TinkerCAD there is no fan DC, so I replaced it with an a dc motor.
Final outcome
our sumo car
I recommend making the armour shield with this slope during the design process to help the driver protect his vehicle from termination.
I was facing a problem with the leds and their polarity. I lost many of them in this assignment to just find out the direction of the electricity, so I got back to Shreif in the midweek session, and he told me that the problem was in the adaptor, as we couldn't power a fan and a led with a 9v adaptor without resistors. He also advised me to do the circuit again in
parallel.

mounting parts
I learned how to control electricity and wire components together and how we can divide the volt into different components at the same time.
Making the sumo car in the end-of-week session was very interesting and urging. It was also exciting to fight with the other colleagues.
