This week, we started working on the coin dispenser, and we tested the colour sensor.
Here, we see Kurt working on the 3D model of the coin dispenser.
He made use of Tinkercad and a 3D printer to create the coin dispenser.

Here, we see Lazim and Krish working on the cardboard variant of the coindispenser. We will be using this one in case the 3D model isn’t working out forus.

And here, Milan and Saim worked online to test the colour sensor.
Unfortunately, unexpected problems came up, and the colour sensor is incorrectly identifying different colours. We are still figuring out why this is happening.
