MQ-4 methane gas sensor registers the presence and concentration of natural gas and methane (CH4). The best results are given when gas is in liquid form, however, since situations like this are rare, it does its job pretty well when in gas form, too. It needs a bit of time to warm up in order to work correctly.
A 7-segment display is classical, often used and already familiar component. Size of a digit on the display is 0.56inch and the light it transmits is red. The display has a common cathode.

If you use some laboratory equipment such as power source, signal generators or, in most cases, multimeters – you’ll find this cable very practical. It has 2 banana connectors – on one end so you could connect it to mentioned devices and on another end to connect it to alligator connector which allows you to connect to almost anything!
Connecting to other devices and controllers from improvised power sources becomes truly simple with this terminal. Just use a screwdriver to tighten your wires to the terminal and you’re ready!

Smaller booster (step-up) module. It increases input voltage to the desired level.
A through-hole holder for CR2032 3V battery which you can find on watches, RTCs, toys, motherboard and other electronics.
BR2032 batteries are also suitable for this holder, but we do have one more battery type for you – CR2032 battery.
Crystal (oscillator) with a frequency of 16MHz.
SMD Battery Holder for CR1220 3V battery, just like the one on our Croduino Damba.
USB mini-b female connector for a printed circuit board (PCB). It’s identical to the one used on Croduino Basic.
H bridge supports an exchange of polarities on its outputs and therefore enables control of motor spins in both directions in a very simple way. It can also direct other devices that for certain usage require the exchange of polarities on their inputs.
This is a pretty ordinary signal diode 1N4148. It is used for signals up to 200mA of current.
Ordinary and well-known rectifier diode 1N4007. It’s often used for rectification of voltage, protection from the wrong polarity, different projects with breadboard etc.
Max. voltage that this diode can endure is 1000V and max. current it can carry out is 30A.
MOSFET transistor N-channel has ideal characteristics that allow it to connect to Croduino/Arduino. With this transistor, you’re able to control devices that need big amounts of current or voltage – all of that via a microcontroller.
A rotary encoder can be rotated endlessly – it has no end. That’s the main difference between it and the potentiometer and the reason why it’s more suitable for usage in certain applications. Its output (rotation outcome) is written in gray code, therefore you’ll need a microcontroller in order to use it.
It also has inbuilt pushbutton which makes it suitable for different selections.
78m05, often used 5V linear regulator in DPAK SMD package.
An alcohol sensor is capable of detecting alcohol (ethanol) particles on itself and gives the information in digital form back to us to manipulate it.
In a buzzer speaker, current is run through a coil of wire that produces a magnetic field. The flexible ferromagnetic disc is attracted to the coil when current is flowing through it and returns to a “rest” position when current is not flowing through the coil. The sound from the buzzer speaker is produced by moving a ferromagnetic disc in a similar way to a cone in a speaker.
NRF24L01+ module enables wireless two-way communication between two Dasduinos. Its range is up to 100m outdoors. With some adjustments of the antenna, the range can be larger.
The membrane keyboard is a system of 16 keys that are mutually connected and enable us more complex entry to Dasduino/Arduino. Using this keyboard, you can create whole systems of menus, data input, and adjustment of different parameters.
Set of male-female cables for connecting to various modules and components. You simply connect the module to the breadboard. It contains 40 cables of different colors, wire length is 15cm.
• Quantity: 40 cables
• Cable length: 15cm
• different colors for easier recognition
A male connector that is usually found on our power supplies. For use with our controllers and amplifiers.
