## Hunter's comment
For anyone who usually works with microcontrollers knows how messy wire connections can get. That is drastically reduced with this new Arduino tuBoard.
**Video on website highly recommended!!!**
This list below is taken straight from the Kickstarter website.
The tuController part contains:
- tuController
- Buttons × 4 - Up and Down and A, B buttons
- Potentiometer × 3 - Three rotary potentiometers (RP0, RP1, RP2)
- LED × 3 - Green, Yellow and Red LEDs
- MicroSwitches × 3 - three microswitches
- Buzzer
- RGB LED
- 0.96 inch OLED di

四位辉光管时钟
[上次做的辉光管时钟](https://blanboom.org/2014/qs30-1-nixie-clock)在外观上还有一些不满意的地方。所以最近这几天,我又新做了一个辉光管时钟。不同于上次,为了节省时间,电路和 PCB 都没有自己设计,而是直接采用成品模块。这样制作难度大大下降,同时能够更快地完成制作。

![辉光管时钟](https://blanboom.org/wp-content/uploads/2016/03/nixie-photo-1.jpg)

# 电路

在电路上,全部使用成品模块进行制作,通过简单的导线连接即可完成。具体介绍如下:

**1) Arduino 兼容控制板**

控制板采用 [Bluno Beetle](http://www.dfrobot.com.cn/goods.php?id=1097). Bluno Beetle 是一块兼容 Arduino Uno 的开发板,体积较小

2015 电赛风力摆题:我的方案
2015 年全国大学生电子设计竞赛刚刚结束。我们组选择了 B 题:风力摆控制系统。题目要求如下:



> 一长约 60cm~70cm 的细管上端用万向节固定在支架上,下方悬挂一组 (2~4 只) 直流风机,构成一风力摆,如图 1 所示。风力摆上安装一向下的激光笔,静止时,激光笔的下端距地面不超过 20cm。设计一测控系统,控制驱动各风机使风力摆按照一定规律运动,激光笔在地面画出要求的轨迹。




趁这段时间,整理一下我们组的方案。

<!--more-->

# 总体方案

作品的机械结构由我的队友完成。支架使用铝型材制作,通过万向节与摆杆相连,底部是由细碳纤杆做成的立方体,四个电机固定在立方体的四个侧面上。

![风力摆照片](https://blanboom.org/wp-content/uploads/2015/08/pendulum_1.jpg)

该题的电路比较简单,Arduno MEGA 2560 产生四路 PWM 波,通过 PMV31XN 驱动各个电机;MPU-6050 用于获取摆的运

[Arduino 库] 适用于 Arduino Uno 的多任务调度程序
一般情况下,处理 Arduino 的多个任务,是把所有任务放在 void loop() 里,然后用 delay() 控制时间。不过,任务一多,这种方法就不太方便了。

最近刚刚看了一本书:《<a href="http://book.douban.com/subject/1168618/">时间触发嵌入式系统设计模式</a>》,里面介绍的调度器,可以以特定的周期执行特定的任务,值得在 Arduinio 项目中借鉴。我也刚刚把这个调度器移植到 Arduino 中:<a href="https://github.com/blanboom/Arduino-Task-Scheduler">https://github.com/blanboom/Arduino-Task-Scheduler</a>

<h1>基本使用方法</h1>

这是一个使用调度器的例子,各个函数的功能都已在注释中标出:

初试乐联网
物联网,听起来似乎很高深。但我在前一段时间发现了乐联网(<a href="http://www.lewei50.com/">http://www.lewei50.com/</a>),它能让每个爱好者都能轻松地搭建自己的物联网系统。

我也刚刚用最简单的方式体验了一下乐联网:将温度传感器的数值以一定的时间间隔发送到电脑,而电脑把这些数值通过互联网发送到乐联网服务器。这样,一个简单的温度监测系统就完成了。(<a href="http://www.lewei50.com/home/gatewaystatus/1415">http://www.lewei50.com/home/gatewaystatus/1415</a>)
<!--more-->

<h1>什么是乐联网?有哪些功能?</h1>

乐联网是一个物联网开放平台,可以把各种设备接入乐联网服务器,通过乐联网集中进行控制。

经过试用,我发现乐联网暂时有下面这些功能:

<ol>
<li>接入传感器或摄像头。可以远程查看传感器数值或摄像头中的画面,并分享给别人。</p></li>
<li><p>对传感器的数值进行简单的

自制 MakeyMakey:更简单的方法
<a href="http://makeymakey.com/">MakeyMakey </a>是一个在 Arduino 的基础上设计的电路板,通过物体的导电性,可将各种能导电的物体变成键盘。它的原理十分简单,但能玩出很多花样。

对于有 Arduino 的人来说,完全可以自制 MakeyMakey。但是,网上的许多方法都需要把 Arduino 模拟成 USB 键盘。这样的话就增加了复杂程度。而直接使用串口向电脑发送数据,同时用串口转键盘的软件,制作难度会小很多(几只电阻,若干根屏蔽线即可),另外还可以实现 MIDI 输出等更多功能。

https://player.youku.com/embed/XNDE5MTcwNzg4

<!--more-->

<h1>制作方法</h1>

<strong>1. 直接按照这篇文章(<a href="http://www.geek-workshop.com/thread-1192-1-1.html">http://www.geek-workshop.com/thread-1192-1-1.html</a>)连接电路,USB 部分无需连接。</strong>

<strong>2. 将下面程序下载进 Arduino.</strong>

Cool DIYs
<br /><center><hr/><em>Posted from my blog with <a href='https://wordpress.org/plugins/steempress/'>SteemPress</a> : https://blanboom.org/2013/cool-diys/</em><hr/></center>

这几天翻看收藏夹,发现近几个月,在上网闲逛的过程中,自己又搜集到了许多有趣的 DIY 创意,以及相关产品。下面将这些东西整理出来,同时与大家分享。

<h1>DIY 项目</h1>

这些都是由其他爱好者完成,比较有趣,且容易实现的 DIY 项目。

<h2>1. 机械数字钟</h2>

机械钟和数字钟,两者似乎很难结合起来。不过,Hans Andersson 的 Time Twister,使用 LEGO 套件制作,没有 LED 或显示屏,却能通过数字直观地显示时间。

DC 모터 드라이버를 이용해서 DC모터 제어하기
이번 튜토리얼 에서는 DC 모터 드라이버를 이용해서 2개의 DC모터를  제어 하는 방법을 배워 보도록 하겠습니다.

 ![1.png](https://cdn.steemitimages.com/DQmeUCK2PyZU4NbEGrcDS6UQEoQzBhTFbEGzzcYuwKXDmss/1.png)

DC 모터는 DC(직류)전원으로 작동하는 모터를 말하며 모형 자동차, 무선조정용 장난감 등을 비롯하여 여러 방면에서 가장 널리 사용되고 있는 모터입니다. 가격이 저렴하고 가볍다는 장점이 있으나 수명이 짧고 소음이 많은 단점이 있습니다

![rc_car_image3.jpeg](https://cdn.steemitimages.com/DQmR5RAJ3NXZS2kmTE35CtGCc2EcWu4rNYGGAVD4hwUPJ4Q/rc_car_image3.jpeg)


DC 모터는 일반적으로 9V ~ 12V 전압을 사용하며. 두개의 핀으로 구성되며 극성이 없습니다. 연결 방식에 따라 모터의 회전 방향만 바뀌게 됩니다.

Project Arduino: Lighting controller in the apartment
For a long time I have been tempted to make myself a reliable light control system in the apartment. Do it, do not buy it ready, because in it all the fun. Long ended on plans, but finally it worked! :)

The assumptions of the project were as follows:

- enabling lighting control at home in the most reliable and simple way possible.
- the dimensions of the controller must be as small as possible, as small as the home production conditions allow.

In view of the above, after verifying my long-term stock of electronic components, I found that I would be fully satisfied with the control using a TV remote control. The remote control usually lies at hand, there are a lot of buttons in it that you do not use, so why not use them to turn on the light?

I used the Arduino to build the prototype in combination with the infrared receiver TSOP 2236 and the integrated Darlington system ULN2003A. The cicrcuit below:

Projekt Arduino: Kontroler oświetlenia w mieszkaniu
Od dawna mnie kusiło, aby zrobić sobie niezawodny system sterowania światłem w mieszkaniu. Zrobić, nie kupić gotowy, bo w tym przecież cała frajda. Długo kończyło się na planach, jednak wreszcie się udało! :)

Założenia projektu były następujące:
- umożliwienie sterowania oświetleniem w domu w możliwie niezawodny, prosty sposób.
- gabaryty sterownika muszą być jak najmniejsze, tak małe na ile pozwolą domowe warunki produkcji.


Wobec powyższego, po zweryfikowaniu moich wieloletnich zapasów elektronicznych podzespołów, stwierdziłem, że w pełni zadowoli mnie sterowanie przy użyciu pilota od TV. Pilot zazwyczaj leży pod ręką, jest w nim masa przycisków, których się nie używa, dlaczego więc nie wykorzystać ich do włączania światła? 

Do budowy prototypu użyłem Arduino w połączeniu z odbiornikiem podczerwieni TSOP 2236 oraz scalonym układem Darlingtona ULN2003A. Schemat poniżej:

LCD에 한글, 영문 문자열 출력하기
이번 튜토리얼 에서 사용되는 디스플레이는 LED 백라이트가 있으며, 두개열에 16개의 문자를 표시할 수 있으며 LCD 라이브러리를 사용해서 다음 그림과 같이 영문, 한글을 LCD에 출력해 보도록 하겠습니다

![unnamed.jpg](https://cdn.steemitimages.com/DQmZUPkz3cW5G384Ye6xxWxtz2jwpB5oKM36aAcUx86pxJZ/unnamed.jpg)


LCD  테스트를 해보기 위해서는 다음과 같이 총 6종류의 부품이 필요합니다

![lcd_list.png](https://cdn.steemitimages.com/DQmQNPWKTRVPHU14mWU3cPGCmaVX1ShqV4SkQSD1WpEzM6W/lcd_list.png)


LCD 디스플레이는 동작을 위해서 6개의 아두이노 핀이 필요하며 6개의 핀은 모두 디지털 출력으로 셋팅되어야 합니다. 그리고  5v와 GND 연결을 하면 됩니다.

Modify STL CAD files for CNC or 3D Print using Python Programming
<br class="wp-block-image"><img src="https://makerhacks.com/wp-content/uploads/2018/07/python-stl.png" alt="modify stl files with python code" class="wp-image-114821" /><br/></figure>

<p>We are pretty familiar at this point with the 3D design creation workflow. Drawing, dragging and dropping CAD files using a mouse and a package such as Fusion 360, or a browser-based application, such as Onshape.</p>

<p>What, though, if you have to create a whole bunch of personalised objects? Opening, editing, exporting doesn't take long per item, but if you have 100, that soon adds up to quite a chore!</p>

<p>A member of a Facebook group had just that issue. They needed to add consecutive serial numbers to a vape design he had created. Initial order was 100 items.</p>

<p>People suggested printing the vapes then lasering the serial numbers. Or maybe hand engraving.</p>

<p>What if you could generate the files with <em>code</em>?</p>

초음파 센서 사용하기
이번 튜토리얼 에서는 초음파 센서를 이용하여 LED를 제어 하는것을 배워 보도록 하겠습니다

초음파센서는 인간의 들을수 있는 가청주파 이상의 높은 소리의 주파를 발생하여, 소리를 보내고 받습니다. 저희가 사용할 초음파 센서의 속도는  대략 340 m/s 이며 약 40KHZ 정도의 주파수를 생성하며, 5~7m 정도 까지의 거리를 측정 할수 있습니다.

거리측정을 위한 초음파 센서는 송신부와 수신부로 나뉘어져 있으며, 송신부에서 일정한 시간의 간격을 둔 짧은, 초음파 펄스를 방사하고, 대상물에 부딪혀 돌아온 에코 신호를 수신부에서 받아, 이에 대한 시간차를 기반으로 거리를 산출합니다.

CDS 조도 센서 사용하기
이번 튜토리얼 에서는 CDS 조도 센서를 이용하여 밝기를 감지해서 LED를 제어 하는것을 배워 보도록 하겠습니다 

이름은 생소하시겠지만 이 CDS 조도 센서는 주변에서 많이 사용 되고 있는 빛 감지 센서 입니다. 이 센서에 빛이 쏘여지면 저항 값이 감소해서 높은 전압이 들어갈 수 있게 됩니다. 우리는 이런 특성을 이용해서 LED를 제어해 보겠습니다.

Project 3: Arduino, HC-SR04 Ultrasonic sensor, NRF24L01 transceiver, Active buzzer
# Description: Ultrasonic alarm system
#### Arduino 1:
* As a person comes closer to the ultrasonic sensor, an active buzzer will ring with higher frequency. The LEDs will also turn from green, yellow, to red based on the object's distance from the ultrasonic sensor.
 * When the person reaches the red zone, RF module will send an alert to Arduino2.
 * Person has to put the pass code in by pressing the buttons predetermined times. If the pass code is correct, the system will disarm. 
* When the system is disarmed, the RF module sends disarm signal

#### Arduino 2:
* When the intrusion alert is received, a passive buzzer will ring. Red LED will also light.
* When the disarm signal is received, the green LED will light.

# Components Used:

#### Arduino 1:
* HC-SR04 ultrasonic sensor
* NRF24L01 RF module
* Green LED
* Yellow LED
* Red LED
* 1kOhm resistor - to limit current to US sensor
* Switch button
* 10kOhm resistor - pull down resistor for the switch button
* 220kOhm resistors x 3 - LEDs
* Jumper wires
* HC
