3. Plate load resistor, adjust the resistance to control the output frequency.
4. Onboard power indicator. 5. Working voltage: 5V~12V.

Features:
After power on, the 10 LEDs will light up sequentially from left to right, showing the state of running lights. This kit can display the NE555 timing and CD4017 counting functions intuitively. It is a starter kit for learning timers, counters, frequency dividers, and lantern controllers. At the same time, the kit has good effects, is very interesting and practical, and is also the preferred material for beginners to get started.
Circuit principle:
This kit is mainly composed of a clock generation circuit and a decimal counter circuit. It is a self-excited multivibrator with NE555 as the core. The power supply charges capacitor C2 through R11, R12, and R13. When C2 just starts to charge, pin 2 of NE555 is still in Low level, so the output pin 3 is high. When the power is charged to 2/3 of the power supply voltage to C2 through R11, R12, R13, the level of the output pin 3 changes from high to low, and the internal discharge tube of NE555 turns on , Capacitor C2 is discharged through R13, R12, NE555 pin 7 until the voltage across C2 is lower than 1/3 of the power supply voltage, NE555 pin 3 level changes from low to high again. C2 is charged again, This cycle forms an oscillation. The charging time is: 0.695(R11 R12 R13)C2, and the discharging time is: 0.695(R13 R12)C2. Adjusting R13 can control the output frequency of the oscillator. The clock oscillation signal of NE555 is constantly added to pin 14 of CD4017. There are 10 LEDs connected to the 10 output terminals of the CD4017. When the 10 output terminals of the CD4017 generate high levels in turn under the action of the clock signal, D1--D10 will be lit in turn to form a water lamp effect. Adjust R13 to adjust the flow speed of LED lights.
Common problem:
1. Take care to avoid wrong welding of the positive and negative poles of the LED, and the long leg is the positive pole.
2. Take care to avoid wrong welding of the positive and negative electrodes of the electrolytic capacitor, and the long leg is the positive electrode.
3. Take care to avoid inserting the chip in the opposite direction. The chip notch and the base notch should be in the same direction as the notch on the board.
4. Take care to avoid wrong connection of the positive and negative poles of the power supply. The correct connection method is to connect VCC to the positive pole, GND to the negative pole, and supply a 3-5V DC voltage.
Pay attention to check the welding for short-circuit and virtual welding.

BT5.0 Audio PRO Mini Bluetooth 5.0 MP3 Decoder Board Audio Receiver MP3 Lossless Player Wireless Stereo Music Amplifier Module Lithium battery charging Incoming call
BT5.0 Audio PRO continues the excellent basic functions of M28 (long-distance transmission, Bluetooth 5.0 backward compatible, lossless sound quality, etc.), and adds more user-friendly performance, as follows: Charge while putting: This product has a circuit of charging and discharging, which can directly charge the battery through the USB power supply, and Bluetooth can continue to work normally during the charging process, and truly realize the function of charging and discharging. Solve the pain point that some products can not be used during the charging process. When powered by USB alone: The red light flashes, indicating that the power supply is normal. When powered by a separate battery: The yellow light is always on, indicating that the battery power supply is normal; the yellow light flashes, indicating that the battery is low. When the USB and battery are connected at the same time: The red light flashes to indicate that the battery is charging; the red light always indicates that the battery is fully charged. (Note that if the USB input is suddenly disconnected during the charging and discharging process, there will be a few seconds of interruption due
to the charge and discharge mode switching at this time, after which Bluetooth will automatically restart, automatically connect and maintain the previous playback state) Incoming voice call function: After the Bluetooth is connected, turn on the call audio mode in the Bluetooth settings. If the phone calls, you can answer or hang up the phone through the PLAY/STOP button. You can choose to send from the microphone of the original headset (provided that the headset has a call function, which is a 4-segment type) or from the onboard microphone (default), see the function description for details. When the computer sound card is used: Tin the pads in the two boxes corresponding to the Sound Card on the back of the module, and then connect it to the USB interface of the computer through the USB cable, which can be used as a sound card. That is, the sound played by the computer is output through the audio interface of the module. See function description for details. (Not enabled by default) Product Size:
