Description:
The eight-way robocaller consists of robocall keys, priority encoder, decoder display circuit, latch circuit, reset circuit, and sound circuit. The priority encoder is composed of discrete components; the decoder display circuit displays the bit number of the robber. According to the situation of robbing, the robber displays the bit number of the priority robber, and at the same time, the buzzer sounds, that is, the robbing is successful. It is a comprehensive training kit to improve circuit analysis and skill operation.

Circuit principle:
D1 ~ D13 for the priority coding circuit, the key bit number coding, output to U1, such as when S7 is pressed, U1 1, 2, 7 pins for the high level, the digital tube after decoding the value of 7. D16 ~ D19 for the diode composition of the four inputs or gate, that is, when S1 ~ S8 there is any key is pressed, the buzzer sounds. After the successful answer, press the key again, the display will not change unless the reset key is pressed. After reset, the display will be cleared to zero and you can continue to answer.S1~S8 are the answer keys and RST is the reset key.U1 is an integrated circuit CD4511 which contains BCD-7 segment latch/decode/driver circuits, of which 1,2,6,7 are BCD code inputs, 9~15 pins are display outputs, and 3 pins (LT) are test outputs.
