ADC for a line follower robot with uC

[HelderS]

line follower robot circuit

Hi, everyone!!

I would like to build a ADC to use it in a line follower robot, this ADC must be 8 bits. This ADC going to be connected to a microcontroller, for example the DS89C420, I would like someone to indicate me some online documentation, or other stuff, that could help me initiate the working and designing of ADC's. Like the one described above.

Lots of Thanks

Regards, Helder Silva

The ADC that will be useful for you is ADC0801. The following tutorial gives an elaborate details doubts Iabout the DSP.

hi u can use avr series micro to use adc since the resolution is about 10 bits and u can set ADLAR bit to get ur result in 8 bit either in ADCH or ADCL...its quite simple......al the best....just read ADC section in datasheet of any atmega series of micro.... it is the easiest way of implementing adc...

If u use PIC micro controller PIC 16f877a... U need not to use seperate ADC.. PIC contains inbuilt ADC u can directly connect IR Input to the PIC . Analog inputs PORT A............

Added after 30 minutes:

k other wise u can go for ADC0804 for ur A/D conversion...

if ur microcontroller not conain inbuilt ADC...so u can interface this ADC with ur Micro controler
