THE PICO’S IP ADDRESS
As we saw in the video, the local IP address allocated to the Pico W may change, depending on other devices connected to and active on the local area network. To prevent this from happening you can provide the Pico W with a fixed IP address in your router’s control panel. You can also scan to see what IP address has been allocated to the Pico using a free tool such as Angry IP Scanner -- angryip.org/ -- I personally use the legacy edition that does not require installation.
RE-SETTING THE PICO
If during your experimentation you end up with a Pi Pico W that executes a program that you cannot interrupt by pressing Ctrl-C or Ctrl-F2 in Thonny, you can return the board to its factory state by holding down the boot select switch, connecting to a PC, and copying over a special UF2 file to reset the flash. You can find a link to this UF2 file at the bottom of this page under “Resetting Flash Memory”:

Note that after execution you will have to reinstall MicroPython. All programs will also be erased. Hence, during program development, it is wise to save your programs on the PC, and of course to keep backups. :)

Chris, you always take me back to my school days of robots and BBC Micros in these videos, and I thank you greatly for that. As great as modern tech is, the idea that we can move a robot with a computer seems as fresh now as it was over 40 years ago and with your delivery, doubly so. Top stuff indeed!

This is precisely the kind of thing that I enjoy most! I tried to get an RPi RP2040, but was forced to settle for a board with the RP2040 included. The Cytron Maker Pi RP2040 includes 2 motor relays and 7 discrete 4-pin Grove connectors. So far it has been a disappointment, but that's likely because this is so different from using Python via GPIO on a Zero W or other CPU packing RPi. It would interest me to see the Maker Pi board run through its paces in your most capable hands as I am without much joy using the board so far. Perhaps you could repeat today's exercise using the Maker Pi RP2040? The whole smash cost me $12 and it will do as I require ... eventually!
3.. 2.. 1.. Activate! I loved watching Robot Wars back in the day, so this is interesting for me. Nice how you can attach these boards together to control a Robot. And make a simple webpage as a GUI controller. Thumbs up, Chris! :)

Importing 2 variables for your wifi, is not for when the device gets stolen, just for video publication (no need for blurring), it also prevents having to change your daily wifi password that may be embedded in various other wifi devices. also some wifi routers have guest network options (+active hours), i would use those. Or make the pico W an access point

Technically, it is most certainly in a robot. A robot is mechanical device under programmatic control, and this is exactly what is going on here.

Considering how much the Raspberry Pi is used in education, perhaps this is something that you could focus on in order to increase your viewership. Because this is a very fun little project, and immediately usable for students. The two main issues there is that students are usually not very rich - so likely wouldn't become Patreons - and that Raspberry Pis (Pies?) are nigh impossible to find at the moment.

Wow. You gave me some ideas. I did not know a pico could do all those things. I think I need to get to the store.
That looks like fun. I'd be interested to hear if you could calibrate it so that you could have buttons for different amounts of turn. For example 'turn 90 degrees left'. I guess you'd need to use that ratio for the motors to work out how long a full turn took as a starting point. Or maybe you could implement variable speed control to the motors.
@ExplainingComputers
Жыл бұрын
Hi Graham. What you ask could be done in two ways. The simple way, as you say, would be to run the motors for a certain length of time -- using sleep command -- having worked out/experimented to get the right length of time. And this would basically work, although it would not be that accurate, as the time would change when the batteries wear down, the tracks could slip, etc. A more sophisticated solution would be to work out the number of motor rotations required, and to fit encoders on the motors so that this could be monitored. If you look at the CU shots of the motors, you will see the shaft extends out of the back, which can allow an encoder to be fitted to measure their actual rotation. So the motors would be run in a loop that would terminate when the number of rotations for a 90 degree turn was reached.

Right turn, stop for 0.5 seconds, left turn. The bigger the robot or motor, the more important it would be to allow it to stop before changing directions.
