The Digit Writing Tutor You need to design a system, named the Digit Writing Tutor or WTutor for short, to teach learners how to handwrite each digit. Your system will get user input defining a digit to learn- only decimal digits are valid. Upon getting a new valid digit, the WTutor must follow it with a single short beep. Using a seven- segment LED display device (SSLED), the WTutor will show the user a digit tracing sequence to manually write the digit on paper. Use your own writing sequence. To make the sequence user-friendly, add a small visible pause in between digit segments. A complete digit must be followed by a short-long pair of beeps, as in TADA!!" Upon getting an invalid input, the WTutor will display a question mark followed by a long beep. (Hint: Use functions to shorten your code. You can implement a pause with an empty counting loop. For readability, it's better to write a function to implement your pause) Figure 1. Seven-segment display device. Implement your design in C language using the MSP430 Launchpad and show all inputs using LEDs. This assignment is due on Friday September 28th at the beginning of class. Submit a hard copy of your source code, a hard copy of the circuit schematic diagram of your system, and your implementation of your assignment to demonstrate its function at the beginning of class. You will need a USB power source (which will cost about $10 at various locations including Best Buy, Target, Office Depot, Home Depot, etc.).Your implementation should start running as soon as it gets powered up. Note that you may use a seven segment display device you have in your personal stock or borrow it from the ECE shop. Please return to the ECE Shop any borrowed components you are not using to allow other students to benefit from the availability of those components at the ECE Shop
