Brushed DC Motor Controller
Project ID:
438789Project Type:
FixedBudget:
$30-$250 USD
Project Description:
Need someone to write a code for an Atmel ATTINY25 for a Brushed DC Motor Controller.The unit can be used with unregulated DC supply. Motor loading can be compensated with inbuilt RxI-type adjustment using Back EMF and a PID algorithm. H-bridge is driven per PWM at 25kHz, thus achieves high efficiency and extensive controlling options.
Speed control value can be set with potentiometer. The ramp feature is used to limit the motor start and brake speed, in other words soften the operation and prevent the occurrence of current spikes and cam be set from 0s - 3s. The current limit limits motor torque that is current; this protects the motor and the mechanics. The unit has separate inputs for brake, freewheel and reverse. Brake short-circuits the motor poles and produces powerful braking. Freewheel detaches the power stage from the motor and leaves motor rotating freely. Reverse changes motor rotating direction; this is done using the set ramp times.
Brake and freewheel bypass the ramp feature.

Iam an Electrical/Electronics engineer who's very experienced in 8,16 & 32-bit microcontroller embedded control system design, particularly Microchip's PIC.
Iam living in Dubai & I did many very professional projects & previously done such projects for friends, which all took grade 'A' & the teacher was shocked with the professional way that these projects were done.
I promise to do a professional & clean job for a 115$ ONLY, but might increase in case additional details are requested from your side.
Please could you send me more details regarding the project & what's expected from me to be delivered.
Best Regards,
Mohamad Hidq less
I dont familiar with Atmel ATTINY25 all right, But I can design PID controller for your motor with descret code. What detector do you use? generator or holl sensor or electropt coder..l?
yes we can do it. we are doing same project for international future energy challange-2009 topic A
Hi mr.ultrawave
Can take your project. The code will be in IAR EWAVR, and test and simulation in Proteus.

We are a team of ten Experienced professionals working on ATMEL AVR, PIC and 8051 embedded projects developing software and hardware.
We have done a similar project for a Temperatirue controlled Water bath Shaker for medical application using ATMEL AVR ATMEGA162, where the shaker DC motor speed is controlled accurately.
We can do this project with ease with our experience and existing proven code.
We quote this project for 200$.
Our Deleverables are
1) TINYAVR based Embedded C code Software.
for Code Vision AVR compiler.
2) Compiled HEX code for direct programming the TinyAVR
Hardware and the motor should be supplied by you.
If you want us to develop the complete hardware Schematics and PCB layout and prototype unit there will be addtional charges of 350$ for one prototype with 0.25 hp DC motor.
Let me know the details and offer from you to work on this project.
