470µF Polar Capacitor

Resistors & capacitors blocks

Resistors and capacitors shape a circuit without switching it. Resistors limit current and set levels; capacitors store charge and release it over time, which is how timers and fades work.

Circuits that use this block

• Next stepCharge it, release itThe left button charges the capacitor (the buzzer blips). The right button lets it discharge through the LED.
• Next stepCapacitor delay-off timerPress the button and the LED stays on for a while after you let go.

Other blocks in this family

• 10kΩ ResistorLimits current. Use one before a transistor's base.
• 100kΩ ResistorA higher value resistor for sensor and timing circuits.
• 100µF Polar CapacitorStores charge. Connect + to the left side.
