Or else, choose the last option for internal Vref. If you want to use the VCC (+5V), choose the second option. Apart from this case, you can either connect a capacitor across AREF pin and ground it to prevent from noise, or you may choose to leave it unconnected. We can supply our own reference voltage across AREF and GND. For this we have a three pins AREF, AVCC and GND. The ADC needs a reference voltage to work upon. ADMUX – ADC Multiplexer Selection Register We will discuss the registers one by one. So, if your application is not sophisticated and doesn’t require much accuracy, you could go for higher frequencies. Greater the frequency, lesser the accuracy and vice-versa. There is a trade-off between frequency and accuracy. Now, the major question is… which frequency to select? Out of the 50kHz-200kHz range of frequencies, which one do we need? Well, the answer lies in your need. For example, a prescaler of 64 implies F_ADC = F_CPU/64. There are some predefined division factors – 2, 4, 8, 16, 32, 64, and 128. It produces desired frequency from the external higher frequency. The prescaler acts as this division factor. So to achieve it, frequency division must take place. But the CPU clock frequency is much higher (in the order of MHz). In general, the ADC operates within a frequency range of 50kHz to 200kHz. This interval is determined by the clock frequency. The ADC of the AVR converts analog signal into digital signal at some regular interval.

Thus, a 0V input will give an ADC output of 0, 5V input will give an ADC output of 1023, whereas a 2.5V input will give an ADC output of around 512. The 0-5V range is divided into 2^10 = 1024 steps. In this case, any analog value in between 0 and 5V is converted into its equivalent ADC value as shown above. This tool can function properly when needed enough light, not too dark or bright that LDR can work according to its function.Suppose we use a 5V reference. At the time of entering the car and detected by an infrared sensor, parking structures simultaneously be printed so that the car park can fill in the appropriate local printed on the receipt.
IR SENSOR CODEVISION ATMEGA16 SOFTWARE
The design of the program using a software Code Vision AVR that uses a C language as a programming language. Infrared sensor will inform the DC motor to open and close the portal parking and the motor movement is restricted by the Limit Switch. This tool used ATmega16 microcontroller as the control center and LDR sensors to detect the presence or absence of an empty parking area and will be displayed to the LCD. Information display system at this parking area is one alternative that can be applied to address the parking problems that exist today. Automated parking systems in modern world it is necessary with the aim of effectiveness and efficiency.
