I agree with you - it has stopped working but I cannot see why?

Thanks for the reminder. I've been concentrating of MicroPython since the Pico came out, mapping the missing bits like sensor driver libraries!. Will return to CircuitPython once I've mastered PIO, interrupts and threads! Interesting board you were using. Where did you get it? It's a shame the soil sensors do not last longer. It rather puts me off.

If you use CircuitPython instead of MicroPython there are many more libraries.

Glad you enjoyed it. Feedback is nice.

Some time since I wrote this!Since you are using a Pico you could try MicroPython. This supports threads. You could use the main core to look after the keyboard and the other to drive the Neopixels. I've not tried it yet (been spending all my time on Explorer graphics.) There is some help in the official Raspberry Pi Picon SDK, easy to download.Best of luck. I'd be interested to know how you get on.

Raspberry Pi Pico & Pico Explorer Workout : 15 Steps - InstructablesThis allows you to define chars and display them. Easy to adapt but a bit time consuming. Give it a go and let me know how you get on.

Thanks - it's nice to get feedback.

Thanks, I've added a note. PS I've still got your expansion boards from when the Mk I Pi came out.

I'm sure you will enjoy it. These might be of interest:Pico Explorer display on full brightness - Support - Pimoroni BuccaneersandPico Unicorn Pack not working in Micropython - Support - Pimoroni Buccaneers

Thank you, Great little screen.

Not a problem. I'd left the unit on with full white on the circle while I had lunch. I only noticed when I took the photos, which were a bit over exposed. (Contrast is tricky when snapping screens.) I cannot see any problem with the naked eye now and I've been using the unit a great deal. Get the base - it is great fun. I think the backlight command is being withdraw - no backlight in the screen? See the Github. Just avoid colour (255,255,255) in large areas for too long.

Thanks for your comments - at least one person downloaded it.I've replaced the file. Hope this is OK.

Sorry I did Spanish in school, many years ago and my French is mainly to do with food, drink and getting a room.. I think the temperature on a Micro:bit is the temperature of the processor and will rise above ambient if worked very hard. Not really accurate. Thank you for the comment.

It all helps to keep the brain working while locked-down! Hope they arrive soon - have fun.

I'm not sure you can change the positions of the colours of the segments on the RYBG bar graphs. I think they have just RRYYYGGGGB LEDS in fixed positions, each with its own cathode and anode. Please let me know if you find a colour changing segment version.

Please send code: arduinolink@gmail.com

Thank you very much. I will start on the next stage - Input/output - very soon.

Great idea, currently away from home. Will try on return.

Thank you for your comments.I agree that I could have coded it more efficiently if I justwanted to drive the displays flat out and appear as bright as possible.I particularly wanted to demonstrate and encourage the useof CircuitPython, much easier to understand than the C, using registers and bits rather than pins, if you are new to coding. (CircuitPython fits between Scratch 'blocky' code and more machine dependent languages and is becoming very popular in schools. Full Python is expected to overtake C++ and Java in industrial use in the near future.) I also wanted to be able to slow the code right down so that you cansee the individual segments turning on and off. The resulting display is brightenough when running at full speed.

I have lights and a light tent but did not use them here. I have good light from my kitchen and lounge windows and use a white paper reflector to help fill in harsh shadows. I think it is the adjustments in Lightroom that make a difference, once you have a sharp image.Have you read jessyratfink's piece on taking photographs?

Hi Paulo,Thanks for your kind comments.I used a Canon 700D SLR with a Canon 18 - 135mm EF-S f3.5-5.6 IS lens. I shoot in RAW and process the images with Lightroom and Photoshop. These were hand held.
