Actuators

We all know these Mini DC motors, especially if you ever took apart any kind of toy. They’re everywhere, now and on Soldered as well. You can use it to make something useful or just reminisce about the times when you were younger.

Relay is a device with enables switching greater loads – ones that require more voltage/current. These relays can be found in our relays breakouts. It has NO and NC pins.

• Current needed for activation (current of Dasduino): 20mA
• Coil voltage: 5V
• Max. DC: 30V, 10A
• Max. AC: 250V, 10A

Smaller booster (step-up) module. It increases input voltage to the desired level.

H bridge supports an exchange of polarities on its outputs and therefore enables control of motor spins in both directions in a very simple way. It can also direct other devices that for certain usage require the exchange of polarities on their inputs.

In a buzzer speaker, current is run through a coil of wire that produces a magnetic field. The flexible ferromagnetic disc is attracted to the coil when current is flowing through it and returns to a “rest” position when current is not flowing through the coil. The sound from the buzzer speaker is produced by moving a ferromagnetic disc in a similar way to a cone in a speaker.
