Load-controlled catapult and a trumpeter
- The catapult should be moved by a servo motor
- It should launch after a projectile is put into its bucket – an IR Photoreflector should detect it
- A LED should flash while launching
- After launching the arm should be moved back to the starting position automatically
- Build a robot car and add a trumpeter on top of it.
- The arm of the trumpeter is moved by a servo motor – it can lift up its hand holding the trumpet
- Moving around, he should blow his trumpet – playing a tune with the Buzzer
- The trumpeter should be started by whistling or clapping that is detected with a Sound sensor
