Muxammad al-xorazmiy nomidagi toshkent axborot texnologiyalari universiteti samarqand filiali kompyuter tizimlari kafedrasi 5330500- kompyuter injiniring (Kompyuter injiniring, at-servis, Multimedia texnologiyalari) ta'lim yo'nalishi

Uskuna

• Ushbu loyihani yaratish uchun sizga quyidagilar kerak bo'ladi:
• • Bir dona 128x64 pikselli KS0108B grafik LCD moduli non taxtasidan foydalanish uchun pinli
• • 10 kVt quvvatga ega bitta trimpot
• • Bitta TMP36 harorat sensori
• • Har xil ulash simlari
• • Bitta non taxtasi
• • Arduino va USB kabeli
• Grafik LCD displeyni 7-1-jadvalda ko'rsatilganidek ulang va ni ulang
• TMP36 sensori 5 V, analog 5 va GND ga.

Eskiz

• Quyidagi eskizni kiriting va yuklang, unda foydalanilgan funksiyalar haqida tegishli sharhlar ham mavjud.
• Kodi:
• #include // include the graphics LCD library
• #include // include the standard character fonts for it
• int tcurrent;
• int tempArray[100];
• void setup()
• {
• GLCD.Init(NON_INVERTED); // configure GLCD
• GLCD.ClearScreen(); // turn off all GLCD pixels
• GLCD.SelectFont(System5x7);
• }

• void getTemp() // function to read temperature from TMP36
• { float sum = 0;
• float voltage = 0;
• float sensor = 0;
• float celsius;
• // read the temperature sensor and convert the result to degrees C
• sensor = analogRead(5);
• voltage = (sensor * 5000) / 1024;
• voltage = voltage - 500;
• celsius = voltage / 10;
• tcurrent = int(celsius);
• // insert the new temperature at the start of the array of past temperatures
• for (int a = 99 ; a >= 0 ; --a )
• { tempArray[a] = tempArray[a-1];
• } tempArray[0] = tcurrent;
• }void drawScreen() // generate GLCD display effects
• { int q;
• GLCD.ClearScreen();
• GLCD.CursorTo(5, 0);

• GLCD.Puts("Current:");
• GLCD.PrintNumber(tcurrent);
• GLCD.CursorTo(0, 1);
• GLCD.PrintNumber(40);
• GLCD.CursorTo(0, 2);
• GLCD.PrintNumber(32);
• GLCD.CursorTo(0, 3);
• GLCD.PrintNumber(24);
• GLCD.CursorTo(0, 4);
• GLCD.PrintNumber(16);
• GLCD.CursorTo(1, 5);
• GLCD.PrintNumber(8);
• GLCD.CursorTo(1, 6);
• GLCD.PrintNumber(0);
• for (int a = 28 ; a < 127 ; a++)
• { q = (55 - tempArray[a-28]);
• GLCD.SetDot(a, q, BLACK); } }
• void loop(]{
• getTemp();
• drawScreen();
• for (int a = 0 ; a < 20 ; a++) // wait 20 minutes until the next reading

• {
• delay(60000); // wait 1 minute
• }} 
• Natija:
