I'm looking for someone with expertise in electronics, arduino, micro controllers, etc. To design a circular LCD/OLED (or similar) countdown display timer. The timer must only countdown days automatically, not hours, minutes or seconds, and be operated by a battery that you would get in a digital wristwatch or car key fob (or smaller). It needs to be simple and basic in its functionality. If I want to set the timer to countdown from 10 days then I push the + button until I get to 10 and if I leave it for 3 seconds it will set on this number. It only requires 3 digits so the max number of days is 999. When the timer reaches 3 days the display changes colour from green to yellow and when it reaches 0 days it changes from yellow to red and flashes. When it goes past zero the next day should be -1, then -2, etc. Spec; 1. Size - it should be 1.5 inches diameter, 2 inches max, and as thin as possible. How thin this can be design will decide whether to proceed, or not. 2. Ideally it would be a touch screen, similar to how an air fryer is operated. 3. The back would have a magnetic case so it can attach to metal surfaces.

Hi sir, For this we have to use RTC because internal timers of any Microcontroller is not accurate, and we can use ATTiny 85 as a controller to make the circuit small. I can do this circuit and complete it in less than 1 day. Thank you for spending your time in my application.

Hi, I can handle the project because i did alot of projects like this one before using arduino. The project where made for controlling stepper motors, bluetooth communication, controlling eletrical hot plate and others. I need to say that the longest part of this project will be to send the PCB to be manufactured. As experience I have 4 years in C programming working in automotive domain. In the past i developed software for instrument clusters and wireless chargers. If you think i have the necessary skills for this, contact me to talk more about the specifications.
