Jancsi and the chest
Programming level 1
Kasperl, Seppel and the chest
P1
How to build
Build static figures
- Static figures
- Let’s build Kasperl and Seppel, his arm should be movable with the axle
- OR
- Build a box with a shaft, with a small slot at the top and bottom that opens axially

How to build
Seppel
- We build Seppel and the crate as a separate robot.
- We build Seppel, mount a servo motor in its waist and connect 1 Touch sensor to it.
- When the Touch sensor is pressed, the servomotor will help the sand to fall into the crate
- We build the crate, the top of which can be closed axially. When it is lowered, the roof pushes the push button in the box
- Using wait until, on the third press of the button, the servomotor that moves the bottom of the crate opens a small gap where the sand falls out

How to build
The robots
- Seppel and the crate are constructed in the same way as P3
- The top and bottom of the crate are controlled by 4 Touch sensor
- The lid opens and closes in steps and the bottom can only be opened when the lid is closed
- The lid of the crate can only be closed and the bottom can only be opened if there is sand in it, this is detected by the robot with an infrared sensor

How to build
Coffee grinder
- The coffee grinder is constructed in the same way as in P2
- The grandmother is built in the same way as in P3, but an accelerometer and a push button are used for control
- Pressing the Touch sensor of the coffee grinder causes the coffee grinder arm to rotate at a random speed, 1 IR Photoreflector is used to measure the rotation speed of the coffee grinder arm
- After one lap, the song plays at the corresponding speed while the arm continues to rotate
