THE CURRENCY EXCHANGE MISTAKE
Programming level 1
Yana's is going to the currency exchange

How to build
The robot
- Build the characters of the scene
- Their heads and arms can be moved on axis
- All the characters can be moved, the whole scene

The currency exchange mistake
P2
How to build
The robots
- Yana and the currency exchange are two separate robotsYana is a robot mounted on a small car.
- She has two blue LEDs in one hand and three red LEDs in the other, and we also install a buzzer on her.
- We build the money changer and its counter, and install two blue and three red LEDs on the counter.
- When switched on, the blue LEDs in Yana’s hand light up, and the robot automatically moves forward to the money changer and stops there.
- The two blue LEDs on the counter light up, the ones in Yana’s hand go out, and then the two red LEDs on the counter light up.
- Then Yana’s buzzer sounds, and the third red LED on the counter lights up.
- Finally, the 3 red LEDs in Yana’s hand light up, the 3 red LEDs on the counter go out, and Yana moves away from the counter.

Yana complains
P3
How to build
The robots
- We build Yana and the money changer in the same way as P2, but we install a photoreflector on both robots.
- There is also a sound sensor on the counter, and the part detected by Yana’s photoreflector can be turned by a servo motor.
- Yana stops automatically when it detects the counter, and the blue LEDs on the counter light up when it detects Yana.
- The sound sensor detects Yana’s buzzer, at which point the third red LED lights up and a part of the counter turns.
- Detecting this, Yana leaves the money changer, similar to P2.

Yana and the currency exchange dispute
P4
How to build
The robots
- We build the counter. On one side, we install a photo reflector, a ramp, a push button, and a blue LED.
- On the other side, there is a red LED and a Yana with a servo motor-driven arm.
- We drop cubes onto the photo reflector, which the robot counts. The blue LED flashes after each cube. We signal the end of counting by pressing the push button.
- At this point, the red LED flashes a random number of times. When it shows the correct number, Yana raises her hand.
