Our kit comes with more than 450 pcs electronic components, All components were carefully bagged and each sort of component is individually separated and packed in an orderly manner.
It also comes with a sturdy and practical storage box, which allows you to store all the accessories in the kit more conveniently, effectively and neatly, prevent them from being lost and damped.
NOTE：This kit doesn’t provide controller board!
We provide a power supply which have On/Off switch button. The power supply can be powered by USB cable or 6.5-9V DC adapter and output 5V or 3.3V voltage.
We also provide USB cable for this power supply, which is hard to find and other sellers do not provide.
Jumper wires can be connected to the pins without soldering and allows quick circuit testing.It also can be used for pin extension of the experiment board, adding experimental items and things like that.
It includes 140pcs solderless jumper wires, 65pcs male to male jumper wires and 20pcs male to female dupont wires, which adequate for various experiments completely.
Potentiometer is an adjustable electronic component. By rotating or sliding the system to change the position of the contact on the resistor, a voltage that has a certain relationship with the position of the moving contact can be obtained between the moving contact and the fixed contact, and the output voltage can be changed.
Potentiometers are widely used in circuits. They can be used alone or together with other electronic components to form electronic circuits with various functions.
The IC 74HC595 consists of an 8−bit shift register and a storage register with three−state parallel outputs.
It converts serial input into parallel output so that you can save IO ports of an MCU. The 74HC595 is widely used to indicate multipath LEDs and drive multi-bit segment displays. “Three-state” refers to the fact that you can set the output pins as either high, low or “high impedance.” With data latching, the instant output will not be affected during the shifting; with data output, you can cascade 74HC595s more easily.
The 4N35 is a 4-terminal universal optocoupler that blocks the electrical connection between the signal source and the receiver of the signal, which effectively blocks electrical connections and interference. Commonly used in signal isolation transmission, switching power supply feedback control and so on. Common circuits include TV power supply parts (remote control switch, voltage feedback control), switching power supply, electric vehicle charger and many other aspects.
Passive or Active Buzzer
An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.
To identify them, if you apply a DC voltage to them and it buzzes, it’s an active.As far as commands go if you want to control the pitch, you would need a passive buzzer.
PN2222 NPN Transistor
The PN2222 can be used as a switch that use a little current from the R3 digital output to control the much bigger current of the motor. Because the small DC motor is use more power than an R3 digital output can handle directly.
LED Segment Displays
LED Segment Display tube is an electronic device that can display numbers and other information. The glass tube comprises an anode made of metal wire mesh and a plurality of cathodes. Most cathodes of nixie tubes are digital in shape. The tube is filled with a low pressure gas, usually mostly neon plus some mercury and/or argon. When a cathode is charged, the nixie tube will emit color light, which is generally orange or green, depending on the gas in the tube.
SW-520D tilt is a commonly available roller-ball type tilt sensor which consists of two conductive elements (poles) and a conductive free mass (rolling ball), encapsulated in the same case. The switch would be in the “off position” in the horizontal positon, “on positon” when raised to 15-90 degree or shakes. When the OFF end of the switch is lower than the horizontal angle by 15 degrees, it is difficult to trigger conduction when shaking. This switch is suitable for triggering small current circuits and is not suitable for power switches.
