This project presents the design and implementation of a dual-fan PWM cooling circuit, integrating a power supply with fan speed regulation.

This research has been initialized in speed control by PWM, where an Arduino Uno was programmed to produce PWM signals. The research also proved speed control to be very efficient by using PWM.

Caption Figure 1 Schematic diagrams of two superconducting flux qubit circuits. The conventional qubit (a) requires an external magnetic field to operate optimally, while the new flux qubit (b ...

Again: this pwm information is also available as the 0-10V analogue signal mentioned above. The rest of the connections are pretty well described by the power circuit diagram (repeated left) and the ...

The schematic diagram shown in Figure 2 illustrates how L298 H-bridge IC can be connected with Arduino to control two DC motors. Two sets of inputs, one for each motor, are provided to control its ...

Arduino library to control brushed DC motors by PWM. It uses optional attached encoders to drive fixed distances. Available as Arduino library "PWMMotorControl". Contains the RobotCarBlueDisplay ...

Let’s Look at the Schematic In a PWM circuit, the 555 timer will output a logic signal “high” and “low” depending on a ratio derived by the value of a few components connected.

The PWM output is set as an external voltage using the “Inputs and Sources” components (remember, the output from the Arduino is the input to the circuit).

Circuit analysis Figure 1 shows the schematic diagram of the H-bridge DC motor driver. As it is clear, the heart of the circuit is two IR2104 MOSFET driver chips.
