在Mac OSX 10.4.9下使用arduino写入程序，总会提示一些can't find some file的错误，尝试更改放置Arduino的路径后得到解决-例如把Arduino程序包直接拖放到桌面，放在“图片，音乐，文稿”之类的分文件夹就会出问题。
PS.我的notebook是PPC Mac,OSX 10.4.9.使用Arduino007.
Here's the custom cable I use to program William's EMSBC Arduino from my USB Arduino. I'll eventually replace the yellow jumper (+5V) with a long wire.
Arduino clone with on-board DS1307 real-time clock. The layout is designed for easy assembly and maximum compatibility with the Arduino Uno, with additional functionality being compatible with the Arduino Mega2560. The auxiliary power connector and optional LM61 temperature sensor are not fitted on this board.

You can either run wires between the BlinkM and Arduino, like on a solderless breadboard, as in (a), or you can plug the Arduino in directly as in (b). BlinkM plugs into the Arduino's pins 2,3,4,5. You can use the BlinkM_funcs.h library to turn two of those pins into a power & ground.
Notice the (Black, Red, Green, Blue) color coding of the BlinkM connections. I find this to be a useful mnemonic for remembering the order of BlinkM's pins.

Bleep Labs PicoPaso being controlled by Arduino. Arduino and bits from Sparkfun. PicoPaso from Bleep Labs. Digital potentiometer controls the inputs on the PicoPaso that would normally be photo-resistors.
Super portable Arduino-compatible thing.
- 3xAAA battery-powered
- RGB LED on PWM pins
- 38kHz IR remote receiver
- ATmega8 w/ internal oscillator running @8MHz
- old Arduino bootloader w/ fuses set to not need ext. crystal
- 15mA idle current
- fits in pocket
- causes small amounts of glee
This is the Arduino/Freeduino schematic redrawn to show "components" that could be omitted for bare-bones use. Eventually, there is supposed to be some accompanying explanations.

Looking to build an Internet connected device? The Arduino Ethernet is the ticket, with an Arduino UNO paired with an ethernet port it's the perfect piece of hardware to experiment with the Internet of Things. Or if you've developed something using an Arduino and an Ethernet shield it can be ported to this board with no code changes (uses the same WizNet W5100 controller).

Our fall Arduino 101 class at Tam Makers is off to a great start. I taught this evening course with my associates Donald Day and Edward Janne on September 14, 2016, at the woodshop in Tam High School in Mill Valley.
We welcomed a wonderful group of seven students, including adults with diverse backgrounds, as well as a high school student. We started by giving our students an overview of the popular Arduino board. We then learned how to light up an LED, add a button to turn it on and off, and play a sound with a piezzo buzzer.
Students accomplished all these steps successfully, and seemed to really enjoy this class and told us they learned a lot from it. We’re really happy that this course is going so well and we look forward to teaching next week’s class.

Just playing around with the GIMP, and found this old pic of my arduino after the Austen make faire. I just learned how to do the gray scale color thing. I thought this was a good pick for it
Motor controller (Eagle schematic)
Designed to be a "standalone", no Arduino board etc... All that remains is the ATMEGA8, the crystal oscillator (and related caps), and 5V regulated power supply. The rest is for the sensor and motor relay.
The Arduino portion is based directly on the documentation found here.
Alarm clock prototype project using a Fios3, LiPo battery, a speaker, 4-digit LED display and a custom connection hub. The alarm is set using a rotary encoder.
An Arduino microcontroller uses a CdS photocell and a set of LEDs to indicate the ambient light level. (Move your mouse over the picture to see explanatory notes.)
Just fooling around because I was bored. Maybe I'll think of a good use for this later.

(I know.. all white wires on a white background make this really easy to follow, lol)

I made this housing for an Arduino Pro that will control my waveguide relay in my 47 GHz radio. This housing is made from 6061 billet aluminum. The cover is held on with a dozen 0-80 screws.
Pretty basic. Each temperature probe line has a 4.7k pull-up resistor connected between +5v and the data pin. Data pins are 4 through 10, and pin 1 is used for sending data to the LCD. The probes are capable of all operating on the same bus, but then I'd have to deal with addressing them individually, and making sure each probe was installed in the correct location. This way, as long as I know which pin it's connected to, I don't care what its serial number is.
Teensy3 (arduino) with two moisture sensors that send MIDI CCs. Water evaporates pretty quickly so the controllers are continuously changing. Works really well. It's a breeze to make the Teensy3 send MIDI CCs and since it's USB you can use it with an iPad with the camera connection kit.
When we created Arduino’s visual identity in 2010, we pioneered brand communication in DIY electronics. Since then, we have helped Arduino define its presence amid growth and change, and recently took care of refreshing the brand and designing a coherent look and feel for its sister brand, Genuino.
There is a nice post on Arduino’s blog about our work.
