Need to create a customized 4 digit 7 segment display, as such it can display 4 digit numbers every 10 seconds. Around 100 numbers will be fed to the 7 segment display and every ten seconds it display these numbers Hello This is regarding a new product development We need to create a 4 digit 7 segment display The entire setup should be able to display 4 digits (which will be predefined and loaded to the system ) every 10 seconds It is like a time based secure opt token, which we are creating for our company Our company wants to limit costs hence we are not using Arduino, we are planning to import parts from china and assemble it here. Due to covid we have a lot of workers with not much work, so we ant to utilize them to assemble we need help in designing a low cost solutions, since the main objective of the product is pretty simple. It only needs to display 4 digit numbers every 10 seconds, based on an internal clock

THIS is Not a BID. I do not have free time at all. But this came up in my email and as an Indian I thought I should offer some help. 1. Choose any cheap 8 bit microcontroller that has an internal oscillator and about 14 I/O Pins (Budget Rs.45 to Rs.60 each) 2. Use a Muxed 4 Digit Display that should require no more than 8+4 12 I/O. 2 can be used for switch (Budget Rs.22 each) 3. If you use discrete displays then the cost can be a bit lower but the PCB cost can go up. With above you need a single side PCB 4. Other than 5V regulator you do not need any other components. Use smart PWM to control individual digit current sink in software. No resistors needed. Less BOM, Faster Production Lower Cost. Note: Charlieplexing can reduce microcontroller cost further by reducing I/O pin but requires more complex programming which may cost you more and is always dependent on the production volume. All the Best Jai Hind
