Infra-red (IR) diode emits light in the spectrum that the human eye can’t see. However, such a diode has its purpose. It is used in remote controllers that send information on wavelengths within the infrared spectrum, e.g. to change television programme. So all you need to create your own remote is one of these diodes and correct data which will be sent!

Banana connectors are quite standard connectors in electronic labs because they allow fast and firm connection.

Over the years of working on new products, prototyping and experimenting, we have collected many different electronic components and PCBs. You could probably have one drawer for which you are no longer certain what it contains. Imagine this on a greater scale- that’s what we ended up with 🙂

Now we have decided to get rid of it. We made packages with these components, tried getting everyone more or less the same value and decided to sell them for HRK30 per pack. Well if you want to try your luck – here’s the chance!

NOTE: All packages are randomly packed and there is no option to select a special package. Since this is a sale, these products can not be returned and no refunds are available if you aren’t happy with what you got.

Small audio speaker ideal for radio and projects including amplifiers. Diameter is only 57mm and yet it provides enough power.

KW12-3 is a standard microswitch – it’s activated by the external force on the lever. Releasing the force we deactivate it. This system is very quick and practical, it allows dynamic changes in the switch. The lever itself is able to rotate – it has a little wheel on the top. Microswitches like these are used in PC mouses, automobile industry, communication devices, microwave oven doors etc.

The Potentiometer 10k THT is a reliable, through-hole variable resistor for precise analog control in electronic circuits. With a nominal resistance of 10kΩ, it’s ideal for volume control, dimming circuits, sensor calibration, and other applications requiring smooth, predictable resistance adjustment. Its robust through-hole design ensures stable PCB and breadboard mounting and long-term durability.
 
Featuring a standard three-pin configuration (two fixed terminals and one wiper), this potentiometer is perfect for breadboards, perfboards, and embedded projects. Its mechanical rotation provides fine control, making it suitable for setting reference voltages, adjusting amplifier gains, or any low-power electronics task.
 
Versatile and dependable, the 10k THT potentiometer is essential for hobbyists and engineers alike. Integrate it with microcontrollers like Arduino or Raspberry Pi for analog input control, and enhance your projects with precise, user-friendly variable adjustment.

These magnetic door switch sensors are already seen, if not – then in old movies for sure where they were used as anti-theft devices, ie. alarm systems. In fact, it is a magnet and the reed switch inside a pair. When they are close to each other (recommended 13mm or less), reed switch closes. Connect it to Croduino / Arduino as an ordinary switch use the detection of open doors, windows, drawers, cupboards etc.

• Voltage: max. 200V, best used 5V Croduino/Arduino
• Max reed power: 100mA
• Max detection distance: 15mm, 13mm recommended
• Dimensions: 29 x 14 x 9mm
• Cable length: 30cm

Classic capacitor 0603 100nF 50V, tolerance 10%. Most often used as a decoupling capacitor.
It comes in a pack of 50 pieces.

Resistor 0603 1k ohm with precision of 5%.

Optocoupler 4N35 is a device that electrically (by light, not by electricity) separates the two parts of the circuit. That means, if a short circuit occurs  on one part of the circuit or any kind of other error that causes malfunction of components, there won’t be any malfunctions to the second part of the circuit because there is no way (since they separated by light) to transfer the error.

To sum it up, this optocoupler is very common and generally, it can be used for all applications.

Come on, everyone knows what the NE555 is! It is unlikely that we could make anything in our store without it, since it is inevitable in any kind of education, and is also able to solve the “time” problems in any type of assembly. It is a timer and can be used to create a pulse oscillator, delays …
