Product Description:
This kit comes with more than 400pcs sensors and components, all carefully bagged and labeled for easy identification. The breadboard power supply comes with a power switch to turn the power on or off, and a male to male USB Power Cable, which is hard to find but not provided by other sellers. 🔌
The Breadboard Power Supply has two power modes: 1) M/M USB Power Cable（included in this kit）; 2) 9V 1A DC Adapter（Not included in this kit）. 🔋
Jumper wires are included in the kit, with 65pcs male to male jumper wires, 20pcs male to female dupont wires, and 140pcs solderless jumper wires. These can be used for pin extension of the experiment board, adding experimental items, and the like. They can be connected very securely to the pins, eliminating the need for soldering and allowing quick circuit testing. 🔌
The 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. 🔌
The kit also includes an active buzzer, which 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. 🔊
The PN2222 is a NPN transistor that 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. 🔌
The 1N4007 Diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible. 🔌
The kit also includes an electrolytic capacitor, which is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal. 🔋
The kit also includes a ceramic capacitor, which uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance. 🔋
The kit also includes resistors, with 10 values, 10R/100R/330R/1K/2K/5K/10K/100K/1M each has 10pcs and 220R has 30pcs. 🔌
LEDs are also included in the kit, divided into 5 colors, Yellow/Blue/Green/Red/White each has 5pcs. 💡
All components are securely packaged and labeled, and well-stored in a sturdy box. Datasheets and tutorials are available to download from our official website or you can contact our customer service. 📦 📚
This kit is perfect for anyone looking to get started with electronics and robotics projects. With all the components included, you can easily build circuits and experiment with different components. 🤖 🔌 🔋 💡 🔊
