Light, sound & motion blocks
Output blocks turn current into something you can see, hear or feel: an LED lights, a buzzer sounds and a motor spins.
Circuits that use this block
Other blocks in this family
- LED 1 (red)Lights only when current flows into the left side (the triangle points the way). Has a 220 Ω resistor built in.
- LED 2 (orange)An orange LED, with a 220 Ω resistor built in. Needs about 2 V.
- Passive BuzzerNeeds a changing signal, such as the Melody IC. A transistor makes it louder.
- DC MotorSpins when powered. Swap the polarity (rotate the block) to reverse it.
