555 pulse width speed control controller kit, electronic assembly and use kit, can be used for school electronic production training, electronic enthusiasts assembly and use.
D1 is used to prevent the power connection from damaging JE555, D2, C1, R1, R2, w1, 1C1 to form a pulse generator with adjustable pulse width. Adjusting the Potentiometer W1 can make the pulse frequency and pulse width output by U1 NE555 change the output pulse through R3, R4, R5, Q1, Q2 to drive and adjust the speed of the motor. D3 and C5 eliminate the Counter-electromotive force generated by the motor to protect the triode. C2 and C4 are used for power filtering, and C3 is used as a stable reference voltage to eliminate interference.
