三频闪仪电路 Triple Stroboscope This circuit enables observation of movement between other stroboscopes. Generation of rectangular signal is based on NE555. This circuit requires a low power supply th
简单的直流电机PWM调速电路 Simple DC motor PWM speed controlThe 555 is ubiquitous and can be used as simple PWM speed controlCircuit Explaination: The 555 Ic is wired as an astable and the frequency i
脉宽调制直流电动机控制电路 Pulse Width Modulation DC Motor ControlOften, people attempt to control DC motors with a variable resistor or variable resistor connected to a transistor. While the latter a
This set of two circuits from the basis for a very simple light wave transmitter. A LASER beam is modulated and then aimed at a receiver that demodulates the signal and then presents the information (
