What are you looking for?

In this project, we made a motorized pinwheel. In other words, we wanted a motor to spin. To solve it, we used a battery of 9V. In order to achieve it, we needed to use a new element: a transistor. This is because when the motor receives electricity, a magnetic field is generated. In consequence, voltage is created in the opposite direction that is conducted to the motor. It is called back voltage.

In simple terms, when the sensor detects light, its resistance changes. The stronger light in the surrounding environment, the lower the resistance value the photo diode will read. By reading the photo diode's resistance value, we can work out the ambient lighting in an environment. The photo diode provided in the starter kit is a typical light sensor. In this arduino tutorial, we will make an automatic light that can adjust itself according to the ambient lighting around it.

Arduino Starter Kit: Project 9. Controlling motors with an Arduino is more complicated than just controlling LEDs for a couple of reasons. However, motors make it possible to move physical things, making your projectsmuch more exciting. Moving things takes a lot of energy. Motors typically require more current thanthe Arduino can provide.

Arduino Stack Exchange is a question and answer site for developers of open-source hardware and software that is compatible with Arduino. It only takes a minute to sign up. Here is the schematic:. The diode in question and the only one here is toward the bottom right of the breadboard. It is to prevent the back-voltage from the motor from harming the circuit.
