Driving electromagnets from Arduino Schematic

I am a electrical engineer. I will do the circuit but I have a question. Why do you like to use PWM? Are you going to variable the duty cycle to increase and deacrease the force? do you like to increase and decrease the voltage between 0 to 12 volts? or do you like to control the current? If you like to control the current you are going to design a DC-DC Converter. I can design both of them

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) Do you want a pcb with some small arduino boards( mini, nano) or with pure atmega328 mcu? I can do this. You need 5 mosfer drivers, some protection cuz of inductive load, drivers can be connected to analog pins, so you can pwm them easily. But you should remember, that electromagnet force cant be linearly controlled like led, for example. You will have some force control, but it will not be linear, it cant be much lower than max etc. Give more info and lets talk. I can design using eagle cad - altium is expensive, I dont have normal version. Your budget $$$ is not serious. I can do this, but not for this money. So Im out if it is final.

Hello sir. I am an electrical engineer best in arduino prototyping and pcb designing. I can help you create the schematics in fritzing and altium designer. I am sure that you will be satisfied by my work. Thanks.

Hi there.I offer you the services for Arduino/PCB designs, I complete the jobs in Altium. I am new on freelancer site, but I am designer expert with 10+ years of experience in Circuit designs, programming, Arduino software development, PCB Layer. You can check our designs in our portfolio. If you want, I will share more designs I completed so far through interview. So I like to discuss the job with you. Lets talk about your project through interview. Thank you.

yes buddy,,,me here to accomplish this task, u will feel brotherhood,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

I have experience in working with Arduino of about 4 years. I have also worked with PWM for speed control. I have programmed Arduino using the basic registers which will improve its response speed.
