I need you to design a controller that accomplishes a few basic functions based a sequence of momentary switch inputs: (One press: ON - Activate Relay A and Relay 1, Two presses: ON - Activate Relay A and Relay 2, Three presses: ON - Activate Relay A and Relay 3, Four presses: OFF - turn off all relays): -Relay A controls a separate controller board that powers an electric motor. -Relays 1, 2, and 3 connect a +12V pin to one of three different outputs. -Additionally, the main microcontroller will receive an input between 10.5 and 14.4V. Based on this input (we have a simple tiered formula), the board needs to output a signal between 1 and 5V (we have the formula pre-determined. It is linear and very very simple).

Hi, I can design and develop firmware for this product. If you need a finished board with all these features fully tested then I can build it and ship to you. We can negotiate on the pricing once you discuss in full details and we have a plan. I am from India. Thanks.

I have over 35 years experience as an electronic design engineer, please see my profile for more details. The current price and timescales are only place holders to allow me to communicate with you I would prefer to work in milestones but cannot define these until I have more details Please can you send me further information such as power supply voltage levels, exact functions fro the analogue input, current output levels etc Best Regards Dave Lelievre

Hi, I've good experience designing electronic controlling circuits, I can design the circuit and send you some tested prototypes and all documentation for manufacturing after your approval. I will need more details about the load that each relay will switch to select a suitable relay. If you have any questions please let me know. Best regards,

your button presses need to act on button release may be the question is, what's the time interval between the presses ? between press1 and press 2 ? you need arduino as micro controller, will suffice all your needs, you an connect buttons to it and trigger the relays as per your button releases and yes we can input 10.5 -14.4V to the analog pin of arduino but you need resistors to reduce voltage down to 5V so arduino can handle and yes arduino can output 0- 5V in proportional to the received voltage to it's analog pin I can do this quickly and I will help you with wiring as well, send me a message please

Would you like a custom PCB design or would using off-the-shelf "Arduino" boards/modules be OK? Regards, Jim

Hy, nice to meet you, I already read your project details, I recommend some of your circuit 1. For the regulator, you can use LM2576 12 volt and 5 volt, 12 volt for the relay and relay output, and 5 volt for the microcontroller and the output PWM 2. For the microcontroller, u can use atmega328 (this is make you simple in programming) 3. And for the PWM for output between 1 and 5 volt, you can use simple circuit using NPN transistor I'm Professional Electronic Design Engineer, Embedded system Engineer, PLC Design and Consultant.

The project seems straight forward. A simple Arduino uno would be enough to do the job. But I still have my doubts regarding your controller preferences or the timing of the switch presses and other things. If you are interested lets discuss in length about the important details that will make the project work.
