The set contains a circuit board with solder markings for the components supplied (see below). The LEDs light up in red, green, white or blue, depending on the variant selected.
The resistors are not divided into positive and negative poles and can be soldered to the PCB in any plug-in direction. The long leg of the electrolytic capacitor and the LEDs is the positive pole and the short leg is the negative pole. The LEDs are plugged in with the negative pole facing inwards and the positive pole facing outwards. The direction of the LM358 circuit corresponds to the direction of the marking on the PCB.
Circuit diagram
The kit comes with instructions, but only in Chinese. The kit can still be assembled and soldered without any problems, as the positions of the components are labeled on the board. Alternatively, you can find a link to an instruction video below.
