Operation Of The Circuit
Microcontroller in 18 and 19. connected uçarına XT oscillator. Oscillator produces the controller in necessary for the operation of the palsy.Depending on the desired led directly to the resource assessment go circuit. Adc 0808 of outputs connected to the P1 controller port, mic. .. The digital information to analog input ADC0808 in 8-bit numeric value döniştürüldükten then transferred to port P1.This is the numerical values in the program to which the color is detected by the lcd, after being subjected to processing.
Proteusta drawn up LDR LDR because instead of linear potentiometer. ADC 0808 of IN7 (analog input) to be converted to the numeric value of the voltage from the end of the process, too, is done in the following way;
The ADC is a digital element ports per unit time, resulting in only 1 and 0,
produces knowledge.
I mean, I cannot say that it is sensitive to the values between 0-5v. The ADC converts the information to a value between 0-255 and 256 volumes of information from the resolution.The 8-bit adc for this application.
As an example, if the value of this port to read the adc Tip 2.1 volts, 107-108, there will be a number such as (2 * 256/5).
From the tip of the resistance values according to which LDR ADC-voltage values, numeric values in this way.
According to the values measured from the tip of the voltages of the ADC was elected to this digital equivalent intervals.
kalt = 36, kust = 60; malt = 64, must = 88; read-only = 114, sust = 152 (kalt = lower limit, upper limit of Red kust = red).
Keil Program Code
The following program to the microcontroller using the header file, the lcd which is connected to the lcd to the ports defined. At the same time, in this file to check for the required lcd functions have been defined. Defined at the beginning of the program by using the program to define the variables in the command.
The Program starts while going into an infinite loop (1).P3 data variable was defined as information from being taken into the data variable P1 and Wicklow.Start = 1; start = 0; the realization of the ADC 0808 of loops begin. When the ADC from the tip of the analog voltage value of the analog dial IN7 8-bit numeric value.
This value means that data is held in the P1 port.After entering the data argument if the cycle is that the range of the value to which the processing range to apply the color name is sent to the lcd. ADC 0808 of çevireme is connected to the end of no. 10, enter thanks to the oscillator. When the tip of the EOC in the program logic 1 Oe will be authorized and analog input şıkışa numerically.
