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.

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.

A phototransistor is a component that is able to detect light. This phototransistor is special because (due to their dark lenses) it detects infrared (IR) light better than the other. Therefore, it is practical for fire detection, sunlight etc.

Soldered has created a module with an LM393 voltage comparator using this sensor. Check it out here.

Smaller booster (step-up) module. Input voltage is increased to the desired level.

• Input voltage: 5-32 V
• Output voltage: 5-35 V (adjustable)
• Input current: (max) 10A
• Efficiency: greater than 94%
• Dimensions: 43mm x 21mm x 14mm

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.

Croduino set for beginners Internet of Things (IoT CSP) is a complete set to start working with the Internet of things. Contains Dasduino CONNECT, microcontroller board with ESP8266 which can easily be programmed from the Arduino IDE. Connection to a PC is made directly using a USB cable. Besides the controller, the set has a bunch of different sensors and actuators, which are often used in projects related to the Internet.

Some of the projects that you can make using components from this set are: Weather page (using BMP180 sensor temperature and humidity, air quality sensor MQ135, LDR), the switch which is connected to the Internet (using 2-channel module with relay, MOSFET or servo motor) notification via the Internet (a motion sensor, photoresistor or other sensor), and so on. Turn on your imagination and make something else!

Kit consists of:

• Dasduino CONNECT
• 2-channel relay
• DC motor
• F-F cable set
• Pressure & Temperature sensor BMP180
• Servo motor – TowerPro SG90
• PIR Movement sensor board
• Air quality sensor MQ135 breakout
• 10k resistors (15pcs)
• 2x 2N2222 transistor
• Photoresistor
• 2x IRF540 MOSFET
• DHT11 temperature & humidity sensor
• Buzzer

For the purpose of automation in working with plants, there is an electronic valve for the water (or other liquid?). If you need a way to control some fluid using a microcontroller, here it is! It is actually the electronic solenoid which when activated, the fluid passes through his pipe, and if not – will not. Accepts pipe diameter of1/2 and at the inlet has a filter for all the unwanted particles.

It does not contain the pump or even some additional electronics, so make sure to have an external pump or use faucet water with pressure which is large enough. Systems that have a reservoir at a higher altitude than the valve, or to be exact, that apply the principle of hydrostatic pressure will not work because the pressure will not be large enough.

• Voltage: 12V DC
• For pipes with a diameter of 1 / 2inch

• Dimensions: 78 x 60 mm

A vibrating motor will provide tactical feedback on your projects! Easy to connect, power efficient and works directly with Dasduino / Arduino. Now your DIY consoles will be more advanced, or you can give your old joysticks a boost in vibration.

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

The Raspberry Pi cable provides direct connectivity to the Raspberry GPIO port and then easily accesses all plug-ins or adapters.

A classic small power with an output of 5V / 2A which will ideally supply your project with an Arduino / Croduino. The output is standard female USB connector (type A). You can directly connect a cable from the PCB to the charger and use it as a constant power source, or it can be used for charging up a mobile phone/tablet. Or for a third purpose ..? In any case, it will be enough!

thermocouple sensor is a temperature measuring device, with its range usually bigger than standard sensors. If you’ve ever bought a multimeter and got some kind of temperature sensor, that is the thermocouple.

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