Hi everyone, I am very glad for this opportunity to show you my project 1. The topic is "Design measuring and displaying circuits of the light intensity in the environment." First of all, let's move on to the block diagram. As you can see, that is the block diagram.
The power supply circuit block provides energy for the electronic components in my circuits. The measuring circuit block measures the light intensity in the environment and turns it from the light signal into an electrical analog signal. The MCU block receives the analog signal, converts it to a digital signal through ADC, then controls and displays it on LCD and PC depending on the codes. I use STM32F103C8T6 as a microcontroller. Now, let's go into detail.
That is the measuring circuit. I use a photodiode to turn the light signal into an electric signal. When the light shines on the photodiode, it creates a current; a current goes through the resistor, here creates a voltage in the output.
Now, let's talk about the displaying circuit. The microcontroller controls the LCD to display the light intensity value measured by the measuring circuit. In addition, it transmits information to PC through a communication called UART.
The power supply circuit showed there covert 220VAC to 5VDC to provide energy for electronic components like LCD, STM32.
Finally, we have these real circuits. Because we don't have much time, if you want to get more information about this topic, please email me at this address. I hope you guys having a good day. Thanks for listening.

Part 3: Grade 10 in teacher Cương's class
As you know, in part 2, we were not classmates in our high school. But we studied together in teacher Cương's night extra Math class, and he was also responsible for teaching Math in class 10A1. When studying, my girlfriend didn't care much about me, and we didn't have many conversations, but I noticed her a lot. That made me pretty sad. However, I still remember many times when she quarreled with Điềm, our classmate; she talked very much. I couldn't stop laughing because of her cuteness. She is really a talkative and funny person. One day, she said she would bear her heart to someone. I asked Hà, my girlfriend's closest friend, and she told me the guy my girlfriend was crushing on was not me. 😢

Part 2: The secondary school graduation exam 😭
In the summer of 2017, we had a challenge called the secondary school graduation exam. My girlfriend and I applied to the same high school. She was famous for her study very good at Math. So I decided to study a lot because of my desire to prove myself by enrolling in 10A1, the gifted class. But, unfortunately, my Math point wasn't enough to pass. So I was arranged in 10A2, and of course, my girlfriend was placed in 10A1 and was also the valedictorian. I was disappointed because the point didn't precisely assess my total capacity. Therefore, we didn't study in the same class in grade 10.

Part 1: Our first met
Me and my girlfriend based on friendship. I first met her in grade 9 in teacher Hoàn's extra Math class. I was a newbie in that class, so I was pretty shy. Before the class started, she had used to chat with me. She was very friendly. I'm impressed by her very shining smile. I've ever seen any girl having a beautiful smile than she. Yeah, I had a special feeling for her at first sight.

Hello guys, this page was created at 2 a.m. Are you wondering why I did that? There're some reasons I'll list down below:
1. For learning English
That's a simple reason and I choose English as my second language. Today, learning a foreign language is very necessary. A bilingual person can advance more in their career than a monolingual person.
2. For teaching my girlfriend
Last night, my girlfriend told me that she wanted me to teach English to her. Knowing my English is not enough to teach anyone, I decided to try my best to study daily on this page.
Thank you guys for your following. I'll be delighted if you give me some comments about my grammar.
