The control system is an important part of the mechanical control system with the output of DC, AC, stepper motors as well as servos as well as light control which is called the flashing technique. now let's review the mechanical and light control system using IC 555 PWM (Pulse Width Modulation) mode. we are going to look that is how to do DC motor control PWM with 555 timer IC. This is used to control the speed of a DC motor. The main component of this circuit is a NE555 timer IC . This circuit can be used to control the speed of a DC motor which is used in different things such as conveyors, turntables, etThis circuit can be used to control the speed of a DC motor which is used in different things such as conveyors, turntables, flash indicator , strobo lamp etc .A PWM (pulse width modulation) controller can be thought of as an (electronic) switch between the solar panels and the battery: The switch is ON when the charger mode is in bulk charge mode. The switch is “flicked” ON and OFF as needed (pulse width modulated) to hold the battery voltage at the absorption voltage. Low power systems are better suited to a PWM controller because: A PWM controller operates at a relatively constant harvesting efficiency regardless of the size of the array. In the 555 IC circuit there is a capacitor connected to pins 6 and 2 as charge and discharge to the 555 IC, while the output can produce a PWM signal whose size is regulated via a potentiometer. as input connected to the user ( manual control ) .
