Pulse-Width-Modulated Motor-Speed Control Circuit
Connected in this manner, an LM317 1-A adjustable-voltage regulator can be utilized to control the speed of a miniature DC motor or to adjust the brightness of a small lamp. The circuit achieves this by modulating the pulse width, and...
Keep The Ramp right
If the ramp driving your PWM-based controller is not linear, monotonic, or is simply noisy, your DC/DC converter will not perform optimally. It is essential to understand how to achieve the best performance from your system. A typical DC/DC power...
Servo Reversers
This project describes a simple servo reverser that can be inexpensively constructed using a CD4001 NOR gate, four resistors, three capacitors, and one variable potentiometer (see schematic below).
The proposed circuit utilizes the CD4001 NOR gate as the primary component for...
PWM Dimmer/Motor Speed Controller
This project addresses a common need by providing a simple circuit designed to dim LED lights or control the speed of 12V DC motors. The circuit employs Pulse Width Modulation (PWM) to regulate the effective or average current flowing through...

PWM rectifier power controller power supply. Visit the page to read the explanation about the associated circuit diagram.
A PWM (Pulse Width Modulation) rectifier power controller is a sophisticated electronic circuit designed to convert alternating current (AC) to direct current (DC)...
Servo Driver
This circuit can be utilized to verify the functionality of servos, assess full travel, detect binding, and identify any drag or rubbing when the servos are integrated into a model. It may also serve as a control circuit in robotics...
A DC motor PWM speed control circuit
Most governors utilize pulse width modulation (PWM) and pulse position modulation (PPM) in their circuits. The 555 timer is commonly used in these applications. The pulse width is typically fixed at 0.5 milliseconds, which is essential for the functioning of...
PWM Waveform Capture
The approaches using on-chip A-to-D converters on AVR, PIC, and Cypress controllers reached sample rates of up to about 60 kHz. Not really very useful for the sort of thing I was thinking about using this for: encoded data, radio...
PWM DC motor speed control circuit
The circuit operates using pulse position modulation, which is a method distinct from the more commonly utilized pulse width modulation for speed control. A 555 timer is employed as a square wave modulator, generating output pulses with a fixed width...
