Hi, I am an expert Electronic circuit designer with lots of experience in controlling dc motors.
I can create Motor control circuit for you with and without micro controllers and with many extra capabilities that you haven't mentioned.
Plus, i can create PCB layout for your circuit as well as per your requirement.
What I can give you?
1. A complete schematic of circuit controlling 5 DC motor.
2. The circuit will be made COT H-bridge or custom H-bridge as you require.
3. I can add extra capability of speed control with a potentiometer for each motor.
Following are the electronic projects that i have made involving DC motor control
(without microcontroller/arduino)
1. Logic Based Wending Machine.
2. Liner follower (Logic Based/No microcontroller)
3. Custom made H-Brdiges with PWM and Braking for DC Motor
4. Industrial Water Tank Level Controller and Indicator.
My Projects involving Microcontroller:
1. Warehouse automation using Line Follower
2. IoT based Warehouse Automation (ESP8266)
3. Fire fighting Robot (As an assistant to the project).
4. Remote monitoring of home and industry through Internet of Things
Please Inbox me for more details and any kind of queries. I'm the best candidate for you for this project as i have lots of background involving projects with DC motors such as robots and industrial control.
