Many thanks - that is a really useful document.

jimmo - brilliant - that code works! Many thanks for your help. Your notes on the bit:bot are extremely useful as well. On your github pages for ncss-embedded is there something I need to have installed so the equations show properly? In my browser they just show as the text eg \begin{equation} V_{t...

Thanks for the replies. I loaded lugo's code onto the bitbot and it just returns -1 all the time, which means it's timing out while waiting for the pulse to finish. Not quite sure what this means. I would suspect the batteries except for the fact that the same bitbot will return ultrasonic distances...

Thanks.

Can't find how to upload an image from my local drives to a post. If I click on the Insert Image icon it just puts the tags img into the post but doesn't open a window to browse to the image file. Sorry if this is not the right part of the forum for this question. Please tell me what is the right pl...

Thanks for your reply. I have no control over the pins, as that's the way the bitbot is wired up. I know it works using the same pin for both because this code in Java PXT returns the distance (albeit not very accurately): basic.forever(function () { basic.showNumber(Math.round(bitbot.sonar(BBPingUn...

I am trying to programme a HC-SR04 ultrasonic sensor mounted on a 4tronix bitbot robot. The following micropython code is from the 4tronix website: from microbit import * from utime import ticks_us, sleep_us SONAR = pin15 def sonar( ): SONAR.write_digital(0) # Clear trigger sleep_us(2) SONAR.write_d...
