Considering the wide use of micro:bit and electromagnetic lock, we made a video that combines the two to apply in life. What electromagnetic lock is? Electromagnetic lock is a locking device that consists of an electromagnet and an armature plate. There are two main types of electric locking devices. Locking devices can be either "fail safe" or "fail secure". Electromagnetic locks are fail-safe by design. (Fail-safe means that if the power goes off the door will be unlocked).
As Christmas is coming, we at Elecrow cannot forget even for a moment our hard effort during the year on working on our CrowPi, from sketching an idea to a reality of successful Kick-starter campaign! We decided to celebrate this Christmas with a special xmas special project using the CrowPi! We all know that during Christmas there is nothing better than sitting under the tree with the entire family and singing Christmas songs, why sing alone when you can have a melody singing for you? Our special project will allow your CrowPi to “sing” some Christmas songs for you using the on-board buzzer. We’ve already created an example that
We have been doing with the CrowPi Python Lessons to encourage people to learn electronics, computer science and programming these days.And now they are done so you can do something by yourself with your CrowPi. As we all know, python is an interpreted, high-level, general-purpose programming language, and now is commonly used in artificial intelligence projects and extensively used in the information security industry, including in exploit development.That’s the reason why we worked out this series of videos to teach you how to programming in python with CrowPi . In addition, you can master the basic common knowledge
My neighbor has a little girl with bad arithmetic. This is a headache when her parents direct her arithmetic, so I want to use Crowpi to program a simple calculator to help people who are not good at computing. My idea is to use the 4 independent buttons on Crowpi as +, - , *, /, and then use the 10 buttons on the matrix button to do 0-9 respectively.When I press these buttons, Crowpi Lcd can display the contents of the button I pressed. When I want to get the result, just touch the touch sensor and it will automatically display the result on the LCD.
With the basic ideas, let's get started. Of course, the first thing to do is always to import the modules we want to use. import math import timeThis is the fourth year Elecrow provide free prototyping for Christmas theme PCB and hold the competition to encourage the makers to create interesting Christmas projects.
Free Prototyping, coupon code: ChristmasPCB
The coupon worth $4.9, can be used 500 times at most. It will expire on 26th. Dec. and each person can only use the coupon once. The coupon is especially for PCB manufacturing service with Christmas theme design. You can apply the discount code on the checkout page as below.
BTW, 10pcs 10cm*10cm max PCB prototyping is $4.9 on the PCB prototyping order page.
We will have Mid-autumn festival(22nd- 23rd Sep.) and National Day(1st- 7th, Oct.) Vacation. Please arrange your order in advance.
Green highlights stands for regular working days. All orders can be processed and shipped as normal.
Yellow highlights stands for days which may bring possible shipping delay of your PCB and product orders.
Red highlights stands for the vacation days. Emails can not be replied promptly. In order to decrease the PCB service delay, we will begin to process PCB manufacturing orders on on 5th. Oct.
All orders can be placed during the holiday.
Living in this new digital age, children coming out from schools more need to become makers or inventors creating their own ideas and creating incredible technology to build a bright future. The BBC micro:bit was designed to encourage children to get actively involved in the computer education and make new things, rather than just being consumers of technology. So, let’s see how to develop the skills of making with this tiny computer which costs less than $15 - which means, anyone can have a micro:bit!
From writing code to sharing your creations, micro:bit is the great way to get kids stepped on the maker journey. Here is a recommended route that will make your kids’ experience as smooth and fun as possible.
