Modular Circuits Buzzer
The buzzer module produces sound when a DC voltage is applied to the terminals. The buzzer is polarized and will only produce a sound when a positive voltage is applied to the positive terminal. When 2-3 V is applied, the buzzer will produce a sound with a frequency of 2300 ± 400 Hz. Compatible with all Modular Circuits kits.

Modular Circuits Capacitor, 0.33 F
This module contains a 0.33 F super capacitor. The capacitor is polarized, requiring that the positive side of a voltage source is applied to the positive terminal of the module. You can use this capacitor with a light bulb module to observe the light bulb dimming as the capacitor is discharged. Compatible with all Modular Circuits kits.

Physics
Modular Circuits Diode
The diode module contains a PN junction diode that allows current to flow in only one direction. Current will flow when a negative voltage is applied to the side of the diode marked with the grey ring. The arrow on the diode symbol indicates the direction of conventional current. Compatible with all Modular Circuits kits.

Physics
Modular Circuits Motor
The motor module contains a DC motor that will rotate when 1-3 V is applied to the terminals. The motor spins in the opposite direction when a reverse polarity is applied to the terminals. The rotation speed of the motor increases as the voltage applied to the terminal increases. Compatible with all Modular Circuits kits.
