“I’m addicted to my phone, which I can not focus on my homework. Every day when I go home, I play with my phone first, then about 10 p.m. I started my homework, which is too late. So every day I went to bed at 2 a.m., causing me exhausted. Which I decide to make a phone coffer, when every day I went home I need to put my phone into the coffer, and until I finish my homework, I can go ask my mom for the password, and take my phone out. My mom will sometimes change the password to prevent me from taking my phone out before I finish my homework. I add LEDs to the original design because without the LEDs, my mom will not know if I hand in my phone or not, which she needs to first enter the password, open the coffer and check is my phone inside or not, which is too annoying. So I add the LEDs which my mom can see from the color of the LED knowing if I did turn in my phone or not. And this can also help me to focus more on my homework and go to bed early.
