Build Steffi. We build the 3 girls in the same way as P2, but we also put a servo motor in Lotte’s shoulder. Trude has 1 IR photoreflector on her hand, her eyes are LEDs.
The 3 girls are mounted on 1 common brain, with 1 push button attached.
Pressing the push button makes Trude turn randomly in front of Lotte or Lisa.
If she turns towards Lotte, the figure’s hand moves backwards. If she faces Lisa, her hand moves forward.
Lisa’s hand is detected by the IR photoreflector, at which point the LEDs light up.
We build a reflex game using the two girl figures.
Lisa and Lotte are static figures, mounted on a common brain.
Both girls have 1-1 LED on their heads (Lisa red, Lotte blue) and 1 green LED in front of them in the middle. 1-1 push button is mounted in front of the 2 girls.
When the program is started, the LEDs flash, then the blue or red LED lights up at random. The task is to press the push button in front of the corresponding girl.
The green LED lights up if the answer is correct, the correct LED lights up if the answer is incorrect.
After 5 rounds, the green LED flashes as many times as the number of correct matches.
