555 pulse width speed controller kit, can be used for school electronic production training, and for electronic enthusiasts to assemble and use. D1 is used to prevent NE555 from being damaged due to incorrect power direction connection. D2, C1, R1, R2, W1, and IC1 form a pulse generator with adjustable pulse width. Adjusting potentiometer W1 can change the pulse frequency and pulse width output by U1 NE555. The output pulse is driven by R3, R4, R5, Q1, and Q2 to regulate the speed of the motor. D3 and C5 eliminate the back electromotive force generated by the motor to protect the triode. C2 and C4 are used for power filtering, and C3 is a stable reference voltage to eliminate interference.
