Week 5 - Journal

when i saw the coin eater example in the assignment , i liked the idea and after search on youtube i found that manual coin saving box , and i decided to make it automatic with two leds light indicators

i used tinkercad to build my circuit to make sure that everything working fine

i'll use card board for the body of the box

and will use cutter and glue to

i started by using 5v power source instead of 9 volt because i wanted the motor speed to be medium speed . and i'll put switch button to turn on and off the saving box with red led power indicator

then green led will turn on when i close the circuit with coin ( the other push button here instead of the coin )
and the same for the motor will work when i close the circuit when the coin touch the two aluminium paper pieces

i connected the led and the motor in parallel

*here i disabled the 1st push button that beside the power source to test the other push button

it was so many

1st the aluminium paper was so thin and sometimes it doesn't close the circuit easily

so it needed more tries

2nd how to connect the motor with the rotating part correctly

and i used wooden dowel and hot glue after alot of measurements

3rd connect all these wires correctly

and i did it after few tries

the rc challenge
it was very challenging and fun time

and me and my team , ahmed and aya

we won it so easily
