I love coffee and believe that a good foam can make it even better. Being able to make great foam at home will be a great idea , so my idea for this week assignment will a Foam Maker for Coffee.
Software: Tinker CAD
1 Breadboard
1 DC Motor
1 Yellow LED
1 220 ohm resistor
Jumpers
9 v Adapter 2 A
On/OFF switch
Pushbutton
Cardboard
I started by placing all the components I needed, such as the Motor, LED, resistor, and switch. I then connected the circuit as follows:
The positive terminal of the power source connects to the right leg of the slide switch
The Common leg of the slide switch connects to the right leg of the +ve terminal of the breadboard
The left leg of the slide switch connects to the -ve terminal of the breadboard
The other side of the switch connects to one side of the resistor.
The other side of the resistor connects to the positive side of the LED and the motor ( the led and the resistor series) with the Motor parallel.
Finally, the negative terminals of both the LED and the Motor connect to the -ve of the breadboard.
I started by placing all the components on a piece of cardboard—motor, LED, resistor, switch, and breadboard. After securing them in place, I connected the circuit as follows:
The positive terminal of the power source is connected to the right leg of the slide switch.
The common leg of the switch connects to the positive rail of the breadboard, while the left leg connects to the negative rail.
One side of the resistor is connected to the switch, and the other side to the positive terminal of the LED.
The LED and motor are wired in parallel, with their negative terminals connected to the negative rail of the breadboard.
Finally, I tested the circuit by turning on the switch—the LED lit up, and the motor started running.
The biggest challenge was that I connected the Motor parallel with the led then the series 220 ohm , this connection limited the current so the motor did not move. I used the Avometer to measure the voltage and the current in each part of the circuit. Then I decided to put the led series with the 220 ohm resistor then I connected the motor parallel with them and It was solved and the motor moved.
