Description:
  The circuit adopts STC microcontroller as the core control device, free of oscillation and reset circuit, and the working voltage range is 2.4-5.5V. Two serial shift registers 74HC595 are used for IO port expansion, and the output terminals are respectively connected to the The VT1-VT8 is controlled by the single chip microcomputer and then connected to the dot matrix common anode driving terminal, and the button K1 is interrupted.
 
  The way to control the display speed of the dot matrix , DC is the power socket, and C1 is the filter capacitor. In the figure, IC1 is a single-chip chip, IC2-3 is a serial IO port expansion chip, and DS1 is a 5mm two-color dot matrix. ISP1 is The program programming interface. If you do not need to burn the program, you can not install it. You can also use its VCC and GND pins to supply power.
 
Parameter:
Work voltage:DC 2.4V-5.5V
 
Circuit principle:
  The most core controller of the single-chip microcomputer is used, which is free of oscillation and reset circuit, and the working voltage is 2.4-.5.5V. Two serial shift registers 72HC595 are used for IO port expansion, and the output terminals are VT1-VT8 is controlled by the single chip microcomputer and then connected to the dot matrix common anode driving terminal, and the button K1 is passed.
 
  The interrupt mode controls the display speed The the the the the the the the the the the the ISP1 is the program programming interface. If you do not need to burn the program, you can not install it. You can also use its VCC and GND pins to supply power.
 
Installation precautions
  All components should be mounted close to the surface of the board, and attention should be paid to the polarity of the integrated circuit, electrolytic capacitor, triode, and dot matrix. The integrated circuit can be inserted into the circuit board through the IC socket, And the dot matrix is inserted into the circuit board through the 12P busbar. on.
