Working Line follower
This line follower works excellently. We used two sensors and Atmega16, Bascom-AVR for programming the microcontroller.
Not much to say, just play the video and enjoy.
Something about ADC's
ADC stands for Analog to Digital Converter. Signals in real life are in the form of analog signals. These have to be converted to Digital signals to be understood by the micro controller. Output given by sensor such as LDR, IR, LM35 sensors etc. are given to the ADC.
In Atmega16 the ADC value shown = Vin * 1024 / 5
where Vin = voltage given by the sensor which is ultimately given to the ADC pin
5V = reference voltage (can be changed..)
1024 stands for the 10bit inbuilt ADC in Atmega16
not getting into the details of ADCs, I will end this topic. I hope this helped anyone out there.
For more info just go through the atmega16 datasheet.
Built this for my time pass..LOLZ.
When i was alone at my house, i wanted to do something for my time pass.
So i built this. I just took two DC motors, clips, pulleys, M-seal, rubber bands etc..
Pulleys are not directly connected to the motor shaft. A pen refill is used for this purpose. This idea was given by RAMAN. First we inserted the shaft inside the refill and then joined the pulley with the pen refill using M-seal. This way we were able to save the shaft from any damage. Of course anybody can do it directly. But then i don't think you can use the same motor anywhere else. Yes rubber bands are there to provide gripping. We were not able to find tyres, thats why we used pulleys.
