All about the 'wait flag' and a complete list of the functions that can use it. Am looking for info.

Like a lot of people who've been playing around with their microbit for a while, I've started wanting my device to perform more than one task at a time. I've come across this old (2016) github post by Nicholas Tollervey (link below) which gives a very brief list of built-in functions that can run in...

Programming ESP8266 on Chromebook in Nov 2019; with both Linux/android apps now accessible, is it easier?

Have been searching online and got a lot of mixed information - some saying that you need an Arduino to sit between the chromebook and ESP8266, because an ESP8266 won't be recognised/accepted directly over USB - is this true? What's the current cheapest/easiest route for someone with only an ESP8266...

Re: Anyone here want to share their stories about the first time they fried a micro:bit? - I'll share mine first.

Thanks all for your responses. To the OP: Yep we've all been there! Sorry about your micro:bit :( But as a sort of counter point (with apologies to the OP): I'm amazed at just how bulletproof the micro:bits are. I've probably seen close to 1000 micro:bits (a milli:bit?) go through some fairly heavy ...

Anyone here want to share their stories about the first time they fried a micro:bit? - I'll share mine first.

TLDR: was yesterday playing around with my first sg90 micro-servos decided to start using an external 6V battery to power servo, to 'protect' my microbit from damage was moving servo around while it was running 6V-positive croc-clip touches the signal/control croc-clip for less than a second POOF sm...

Re: Randomization, experimenting with my FIRST :) servo - trying to randomize an infinite loop

Thanks for that :) - have it working now. A few changes: got rid of the list and replaced it with a standard 'randrange' - also, added randomization to the pause between direction changes. Can my code be tidied-up or shortened in any way? from microbit import * import random pin0.set_analog_period(1...

Randomization, experimenting with my FIRST :) servo - trying to randomize an infinite loop

Hi, Please have look at my code below and tell what is wrong. Code description - An infinite loop which turns a 180 degree servo all the way to the left, and then back 180 degrees all the way to the right. Left to right, forever, but with some additional randomization. What I want it to do is turn a...

Looking for suggestions for a cheaper microcontroller - compatible with basic code used on a microbit powered prototype.

Hi, This is all hypothetical . . . Am planning to home-manufacture a small batch of 20 moving statues, all identical, and with the same basic lighting/movement. Am looking for suggestions for a cheaper microcontroller - (will need to buy 20 of them) - that will be compatible with the micropython-mic...

Re: Microbit hardware revisions - v1.3b or v1.5 - any important differences?

Thanks for that. You're right. And, I've just now done a bit more googling, and found this (link below) . . . ( still don't know if speed or response-times were effected in any way; maybe the earlier version was better? ) https://support.microbit.org/support/solutions/articles/19000087020-micro-bit-...

Microbit hardware revisions - v1.3b or v1.5 - any important differences?

Hi folks, this is my first post :) Regarding hardware revisions of the microbit - Are there any 'performance' differences between the earlier v1.3* and the current v1.5 boards? For example, would a short program containing an infinite-loop, running at maximum speed (without calling the 'sleep' funct...
