This is a 3AMP DC Motor speed and direction controller using MC33035 IC from on semiconductor, though the MC33035 was designed to control brushless DC motor , it may also be used to control DC brush type motors. MC33035 driving a Mosfets based H-Bridge affording minimal parts count to...

Giovanni Carrera writes: The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller ATmega328 and numerous other chips, such as the PIC. One of the more interesting applications of this circuit would be to replace or to realize a smart...

Lucky Resistor has build a PWM fan controller using Arduino and DHT22 sesnsors. The fan controller described on this project page, controls one or more PWM controlled 12V PC fans. It uses the input from two precise DHT22 based temperature sensors. The MCU is an Arduino Uno, which is...

baelza.bubba @ instructables.com build his own PWM controller which is able to operate as a 12V Motor Speed Controller, LED Dimmer, Heat controller, voltage controller for an electrolytic etcher etc.   I did some hunting around on the interweb and found a pretty good starting...

Tiny module is a PWM Solenoid and Valve driver using Texas instrument’s DRV103 low-side DMOS power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, motors and...

Smartec has commenced selling a new temperature sensor as the successor to the SMT160: the SMT172. The SMT172 has a superior performance, such as a very low power consumption (60 μA) , a very high accuracy (0.1 °C) and a very high resolution (0.1 mK). [via elektormagazine.com] For...

This tiny module has been designed to use in Robotics, Power tools, automotive applications. The module based on MC33886 from NXP, MC33886 is a monolithic power IC comprising control logic, charge pump, gate drive, and low RDS(ON)MOSFET output H-Bridge circuitry in a small surface...

One of our visitors tipped us with his latest project, an Arduino RGB LED controller using low Rds-on MOSFETS, designed in Solo-PCB. This Arduino shield is designed to drive RGB (Red Green Blue) LED strips by using PWM (Pulse Width Modulation) method. It can brighten up and down each...
