PWM - Pulse Width Modulation for DC Motor Speed and LED Brightness 2
To understand how the 74AC14 PWM circuit functions, it is essential to focus on the schematic section that includes the trimpot, diodes, capacitor, and the first inverter logic gate. Initially, when power is applied to the circuit, the capacitor is...
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...
Control motor PWM schematic
There are two primary methods to control the speed of a DC motor: by varying the supply voltage and through pulse width modulation (PWM). The first method is less convenient, particularly in digital systems, as it necessitates the use of...
UC3842AN PWM IC diagram
The UC3842AN is a pulse width modulation (PWM) integrated circuit that is commonly utilized in DVD, VCD, and SVCD players, as well as in computers, display systems, and various household appliances' switching power supply circuits.
The UC3842AN is a versatile...
Serial Servo Motor Controller
The first servo controller project at http://www.rentron.com/servo.htm had the com port fixed at com1. This new version will seek out the available com ports on your PC and then let you select the desired port and baud rates. It has...
Single-channel remote control
In this project, we will see how to build a single-channel remote control. It is an easy project to do: by using a pre-assembled radio module, we will get a compact card without sacrificing major performance. The insert function allows...
Circuit diagram of an analog circuit PWM
The image illustrates a circuit that utilizes a linear potentiometer (or linear Hall element) to control the PWM generation for two chassis drive motors in a gamepad or joystick used in model aircraft. J1 represents the handle of the potentiometer,...
12V Speed Controller/Dimmer
This circuit serves as a speed controller for a 12V motor with a continuous rating of up to 5A or as a dimmer for a 12V halogen or standard incandescent lamp rated up to 50W. It regulates power to the...
Remote-Controlled Switcher
This single-cable system transmits composite video (NTSC, PAL, or SECAM), power, and channel selection signals. The interface end of the circuit delivers 10 V down the cable, pulses the supply voltage to transmit channel-change commands, and buffers the received video...
