  • I would like to create a light follower which is capable of detecting and following the light source on the traveling path.

    The light following robot includes: CodeBug, 2 phototransistors and 2 gear motors. The light will be used to steering the robot.

    If the light falls on the left phototransistor, the robot will turn left. Likewise, the robot will turn right if the light falls on the right optic sensor.

    I was planing on doing the Line following robot design with my codebug.

     

    The Line following sensors I have pull high when active, Codebug has internal pullups on the legs so we will need to use a transistor to invert the sensor output signal. (unless we find a line sensor that pulls low when activated).

     

    Here's what I've done so far: https://bmsdoug.wordpress.com/tag/codebuggy/

     

    The first codebuggy I saw was by Mike Redrobe http://codebugforum.co.uk/viewtopic.php?f=11&p=165#p165

    his servo driving code is here:  CodeBug – Code buggy - Servo Rover

    The pull-ups must be pretty high in value. One of these projects pulls the input down using body resistance to GND. I measure about 2Mohms left hand to right hand [just measured myself with a multimeter], so the pull-up is probably a good bit higher than that (10M or 22M perhaps?). If you add your own pull down of 47k, or something like that, it will easily defeat the onboard pullup and you should then be able to just run your sensor output straight into it without inverting.

    I had thought that would be the best approach, so I asked on the CodeBug website (In the Experimenters Kit Tutorial):

    I'd like to connect a peripheral which will pull it's output high (5V) when it's condition is satisfied, all of the instructions I have found so far indicate how to operate a switch that connects to ground rather than one that pulls high. Should I add a physical pulldown resistor (as there isn't a pulldown option in blockly)? Will I need to add a voltage divider to the output to drop the voltage level onto the input leg?


    I (eventually) received the following reply:

    CodeBug has pullup resistors so the inputs default to high. To achieve what you need you could use a transistor to pull the pin to CodeBug's ground when your peripheral
