[Program Microcontroller with MicroPython RTL8722 port]

Microcontrollers are known for its low power usage and limited resources thus often deemed unable to understand Python script as Python need interpretor to translate script into machine langauge and intepretor are usaully quite resource-consuming. However, MicroPython has arisen as a lean and efficiant Python 3 interpretor that can be run on ARM Cortex-M series microcontrollers.

 

Ameba RTL8722 is an ARM Cortex-M33 microcontroller that has dual-band WiFi and BLE 5.0, other than that it is fully capable of running MicroPython and controls WiFi using Python script. In addition, its requirement for developing platform is also quite minimal-- only needs a serial port terminal like Tera term. Here is an example of RTL8722 controlling WiFi using just a few lines of Python code on Tera Term,

 

from wireless import WLAN
wifi = WLAN(mode = WLAN.STA)
wifi.scan()

 

Right after the last line, you will be able to see the result printed on the Tera term almost immediately,

 

Hope this post give you some ideas of how easy it is to control microcontroller using MicroPython, stay tuned and happy coding!

You should pay attention to books devoted to Tesla coils themselves, their operating principles, design and application. Look for literature that matches your level of knowledge and interests in electronics. I usually ask do my assignment if I need something, I use https://edubirdie.com/do-my-assignment for this. I don’t really like searching for a long time for a book or information in it. Also use the resources of online stores or libraries, this may help.

[Gaming on Raspberry Pi (or any other ARM devices)]

A lot of people asking if it's possible to play games on Raspbian. More than possible! Learn different ways of playing games on Raspberry Pi in this article - https://eltechs.com/gaming-on-raspberry-pi  



There is a large community of developers supporting ARM platforms, providing a wide selection of games. From retro designs to modern emulators, Raspberry Pi is great for gaming experience. But I’ve already moved on from this, started studying bonus india, found no deposit casino bonus india and am following it closely. Until recently, I was only interested in games alone. Time flies very strangely.

Yes, it is absolutely possible to enjoy gaming on Raspberry Pi and other ARM devices running Raspbian.

[vehicle tracking using gsm+gps i am willing to pay for design and description]

i am a new member & is looking for help from you guys.
basically it should deal with location update of vehicle at any particular time using gsm+gps system. ??? ??? ???

Sorry that I am writing this after so many years. But I really want to share my experience.

In my project, I implemented location data transmission over GSM network, which provides wide coverage and stable connection in various conditions. The use of a GPS module allows you to accurately determine the coordinates of a vehicle in real time. To update the location at any given time, I have integrated software that allows you to query the location data remotely via the GSM network. This provides flexibility and efficiency in managing your fleet or individual vehicles.

[Help for a school Physic Projet ''Bulding a FM transmitter '']

Sounds very interesting! Please be aware that working with radio signals and FM transmitters may require some knowledge of electronics and radio engineering and may involve legal restrictions. It is always important to comply with local laws and standards when creating such devices.

[what is the best electronic book?]

"E-books are not my thing! Although they are convenient and eco-friendly, I always prefer the feel of paper pages between my fingers. I find a special charm in the smell of fresh printing and the rustle of paper that no screen can replace. Each physical book becomes special - a unique literary treasure on the shelf. Flipping pages is like a journey through history and fantasy. Plus, when reading paper books, I get away from the screens and enjoy a well-deserved rest for the eyes. Perhaps in the future many will switch to electronic formats, but for me there is nothing better than the feeling of a real book in my hands!"

[Fridge Protection]

You could use a time delay relay. This relay would be connected in series with the power supply to the fridge, and would delay the power to the fridge for a specified period of time after the power supply to the relay is switched off.

1. Begin by selecting a time delay relay that can handle the voltage and current of your fridge. For a 240V AC circuit, you could use a relay rated for at least 10A.

2. Connect the 240V AC IN to the input terminals of the time delay relay.

3. Connect the AC OUT of the time delay relay to the fridge.

4. Set the time delay on the relay to approximately 10 minutes (or whatever time delay you prefer). The exact process for setting the time delay will depend on the specific relay you use, but typically involves adjusting a potentiometer or dip switch.

5. Test the circuit to ensure that the fridge is not powered until the delay period has elapsed. If necessary, adjust the time delay on the relay until it meets your requirements.

Try it, hope it helps

 

[Request help for college project]

I used these points while creating my college project:

Planning: The first step is to figure out what exactly you want to build. Consider the size of your landing deck, the number of LEDs you want to use, and any other features you want to include. Draw a rough sketch of your project to help you visualize it better.

Gathering materials: Once you have a plan, you'll need to gather the materials you'll need. You'll need a breadboard, LEDs, resistors, jumper wires, and a power source such as a battery pack. You can find all of these components at an electronics store or online.

Building the circuit on the breadboard: Using your schematic and the components you gathered, build your circuit on the breadboard. Start by placing the resistors on the breadboard, then connect the LEDs and jumper wires as necessary. Be sure to follow the correct polarity for the LEDs.

Testing the circuit: Once you have built the circuit, test it to make sure it is working properly. Connect the power source to the circuit and observe the LEDs. If they light up as expected, then you're good to go. If not, check your wiring and component placement to ensure everything is correct.

Building landing deck: Once your circuit is working properly, you can build your landing deck around it. This could involve constructing a frame or platform, attaching the breadboard and LEDs to it, and adding any additional features you want.

Final testing: Once your landing deck is complete, test the circuit again to make sure everything is working properly. Adjust the circuit as necessary to get the desired results.

 

Hope it helps you!

[Doubt Chemistry CR2032 battery]

I can speculate that the chemical composition of the CR2032 battery contains cobalt, manganese, and lithium, but I am not sure if it can be oxidative corrosive to metals and PCBs. Perhaps, with the passage of time and storage, the chemical composition may change and transform into a corrosive oxidative compound that can leak and corrode. I usually use this source with  coursework writing help for some of my study tasks, this resource helps students with basic tasks. But it's better to find something useful for obtaining more detailed information about the chemical compositions and properties of various substances and materials. Maybe if someone has any materials - you're welcome to share them with us.
