iam making a line following robot without using a microcontroller. i was wondering how would i connect my ldr sensors to a computer so data can be analysed. i done some research and i found out that i need an a/d convertor, but iam not sure how to connect it up. :/
my general idea is to get data from sensors that will be send it to a computer from sensors then the computer will tell the motor whether to turn left or right by stopping either the left motor or the right motor. iam not sure how the computer will send the data to motor wheels any suggestions?
Communication… Pretty simple here… Easy enough to get a sensor plugged into a computer. Same with the motors. There are a lot of boards out there for this. Now, these board are going to be on the line follow robot. Is there going to be a big wire connecting the two? If you go with RF or IR you will need a microcontroller to decode the serial data coming from the RF control. Now if you plan to put the whole computer on top of this robot, I am confused as to why you want to get so complicated… If it is just a line follow, why are you anti-microcontroller? Really, MUCH cheaper, easier and really, we are only talking about 100 lines of code or so.
Google and Wikipedia are your friends. Boards = circuit boards, in this case CtC is talking about pre-made circuit boards that plug into your computer via serial/USB/etc and give you inputs and outputs that your computer can use. Here is an example. RF = Radio Frequency, radio frequency transmitter/receiver pairs can be used to create a cheap and simple wireless link between two devices, such as your computer and a robot. Here is an example.
