This Arduino project implements a servo controller for the Bosch 0132008600 throttle actuator, using Speeduino's PWM idle output as input and Track 1 of the Bosch 3437022 TPS for position feedback.

I wrote this when I could not find Arduino code online that could accurately and reliably read 25kHz pwm signals. For reliable PWM you must handle the following edge cases: 100% or 0% PWM signal with ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

Microcontrollers are digital devices at heart. They can do fancy things like convert analog signals into a digital value but going the other direction is a bit tougher. Pulse-Width Modulation is used ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

The 16-channel 12-bit PWM/Servo Driver, PCA9685, is an ideal module for precise control of multiple PWM outputs that are commonly used to control servos, LEDs, and other devices in applications such ...
