In Tinkercad I assembled the inputs and outputs using a breadboard. I connected the servo motor to the positive and negative row on the breadboard. The signal of the servo is connected to pin 13.

After making the physical circuit I struggles with the motor driver so I changed back to a fan. I also struggled with the potentiometer so I chose the ultrasonic sensor to be activated automatically upon approaching the bubble machine.

Making the circuit on Tinkercad was helpful to visualize initially, but I changed a lot throughout the week by trying to connect each input and output one by one. 

I added all parts to the cardboard and reconnected the wires.

For the bubble mixture I used soap and water. I couldn't find the blowing stick in regular stores around me, so I decided to burn a hole in the spoon for a short time solution since there is a deadline.

I used the spoon and container first to allign the distance and position of the fan and the servo motor. I used a longer container because I saw in the inspiration videos that the aggressive movement of the servo can cause some splashes and drop.

The movement of the arm is good and the positioning.

Yet no bubbles were produced in the first half minute. The splashes were too big. I think having the store bought or 3D printed slotted handle for the bubble blowing would be less messy.

I also think the fan is too weak and/or the hole for the bubbles too big.

I struggled a lot with the practice videos and making the code for the circuits using only text. I pushed myself to keep searching for extra videos on Arduino and now I find myself enjoying them a lot. 

So this week I learned that even though something is hard and intimidating, I can push through that bad feeling and might even come to enjoy something I was averse from in the start. 

In the first weeks of the diploma, the learning curve was easier since I already loved laser and 3D machines.
