5.5 YOUR OWN CIRCUIT

In the fih project of our electronics adventure with the Explorer Set, we explore the fascinating world of light control. This time we are building a circuit

that you can use to control LEDs. This provides a fantastic opportunity to understand the principles of electronic circuits while gaining control over lighting

eects.

LEDS: LEDs, or light-emitting diodes, are small but powerful light sources that are used in many electronic

projects. They have many advantages over traditional light bulbs, such as a longer lifespan, lower energy

consumption and the ability to light up in dierent colors. An LED consists of a semiconductor material that

emits light when an electric current flows through it.

It is important to recognize the correct polarity of LEDs, as they only work if the current flows through them in

the right direction. This means that the positive pole of the power source must be connected to the positive

end of the LED and the negative pole of the power source must be connected to the negative end of the LED.

This is how you recognize the polarity of an LED:

Longer leg: for most LEDs, the longer leg is the anode (+), i.e. the positive connection. The shorter leg is the

cathode (-), i.e. the negative connection.

Flat edge: There may be a flat edge on the side of the LED housing. This side usually marks

the cathode, i.e. the negative pole.

First reconstruct the circuit as shown in the following diagram. But make sure that the

polarity of the LEDs is correct. Also use a 56 Ω (green-blue-black) series resistor for each

LED.

ATTENTION! For this project, it is necessary to set the switch for

the TFT DISPLAY to OFF.
