Lcd. LiquidCrystal_I2C lcd(0x3F,16,2) // set the LCD address to 0x3F Analog-to-Digital Converters Terminology analog-to-digital converter ADC A/D AtoD FunctFunct onion transform an analog signal into a digital signal for use (calculation, storage, decision making) in an digital system e.g., a microcontroller Motivation the real world is analog A/D needed to interface real world. Note: This code might not work exactly as you need to calibrate the LDR according to your device. Lcd.print(ADC_O_1, BIN) // Converting to binary formÄifferent colors have different wavelengths and hence different energies as the energy of an electromagnetic wave are dependent on its wavelength and frequency. Lcd.setCursor(4,0) //Set cursor to character 4 on line 0 This board uses the ADC0808 chip from National Semiconductor. LiquidCrystal_I2C lcd(0x3F,16,2) // Address of the I2C module and LCD size This simple A2D (Analog to Digital) Converter Board can log upto 8 channel of analog signal with 8 bit resolution. #define F_CPU 16000000UL // Setting CPU Frequency 16MHz Complete Code: #include // AVR/IO.H header file
