Regarding the sensitivity values which one should i use (max=330 , min=270 , typical=300) ?
Providing that am using 3.3v to power the accelerometer and the arduino board is powered by I2C cable.

and the offset will be solved by subtracting the zero bia...

Something wrong with my Arduino

I just got a usbtinyisp because I would like to program standalone microcontrollers. Before I want to try to program microcontrollers, I decided to try to upload a program to my Arduino. So I connected my Arduino to the ISP, then I tried to upload a pr...

Hello,
On Hardware Side:
i have rebuilded some Boards to replace Pin Headers with Connectors. I also ordered many Connectors to connect the additional Sensos to sthe Systems.
I ordered some 3,5mm Audio Jacks to connect the sensors and 25m Shielded 4 l...

Hello,

I would like to add LED lights to my childrens ski helmets. Basic idea is to have two small "antennas" (or Mickey Mouse ears or whatever shape they choose), two LEDs on each. Red LEDs directed backwards, white LEDs directed forward. Purpose of L...

Your code is not updating the value of currentState when you change screens so it will always be the same value.

Look at this again

Screen 1 on display. currentState = 1
button 1 pressed. Set currentState to 2 and show screen 2

Re: Probleme mit I²C Bus wenn Arduino an externer Stromquelle

Ahhhhh, ihr verwirrt uns total smiley

Also nochmal: Wir haben im Moment 12V an der Runden Strombuchse (rechts neben dem USB Eingang).
Ist das nun gefährlich für den Arduino Mega oder nicht (ist der AT Mega davon betroffen)?

Sorry, I'm not sure what you mean by, "Almost only remaining?? - bad Arduino?"
Could you explain how to Clone Arduino with the wrong USB internal data? Is this a possible solution?

Meet a Shenzhen Maker: Mr. Chen #makerbusinessmonday #makerbusiness

MrChen

Here's an interesting profile of a Shenzen maker from the low-cost pick-and-place scene, shared by Hoektronics.com:

I've been living in Shenzhen for almost 2 years now, and I'm continually amazed by this city. The people here are creative, it has the best resources for building things you can find anywhere in the world, an amazing climate, and friendly people everywhere. This is the story of one particular Maker I've met in Shenzhen, Mr. Chen.

In my ongoing obsession with digital fabrication and small volume manufacturing, I stumbled upon the Chinese SMT Pick and Place scene. It started with the TM-240A that I found on Taobao and through that I discovered www.diysmt. om and oursmt.com. It turns out there are a bunch of people building and using low-cost pick and place machines for actual production of real products. I had to find out more.

I used my super-crappy chinese skills and posted in the diysmt forum to see if anyone was local to Shenzhen and could show me their machine. I got a couple responses, and Mr. Chen agreed to meet me and show me his operation. Always down for an adventure, I agreed and got his address. My assistant/translator and I hopped in a taxi and away we went….

Each week on the Adafruit blog we post up about amazing companies, people and articles about being a MAKER and a business. Over the years we've shared how we run Adafruit, published code from our shopping cart system and given presentations on running an open-source hardware company. Every Monday we're going to try to collect some of these resources and tag them #makerbusinessmonday & #makerbusiness. They're in our popular Maker Business category as well, enjoy!

Hello,
If anyone can provide a quick reference..........
Is sei() an AVR assembler macro ?

SensorChibi: Adding Hall Sensors to Chibikart with Hall Sensor Boards #makerbusinessmonday #makerbusiness

Posted: 21 Jan 2013 12:00 AM PST

HallSensorBoardMounted

Here's some news from Charles from the Democratic People's Republic of Chibikart project — a compelling discussion of his process incorporating motor sensor elements into his project, and the boards he will likely release as an official chibikart product soon — thinking that is already being picked up by other DIY motor-related projects such as TinyBike.

From etotheipiplusone.net:

They've made some appearances here and there on my website and others already, but if you haven't seen them yet, now is the time that I'll make them public. For a while, I've been sproadically making Hall Effect sensor "adapter boards" that can be mounted to R/C outrunners for sensored commutation uses, needed for most ground / vehicular applications. It's about to get way less sporadic.

Yep, that's a big cake of them to the left. I've also added sizes to the collection. Now, 80mm ("melon") motors and 50mm outrunners are supported, also. I'm still a bit peeved that Hobbyking had to make their new SK3 "63″ motors actually 59mm in diameter, necessitating a fourth board design. These boards were sent to my usual slow-and-easy PCB house, MyroPCB, and done up in black.

Why 50mm? My general belief is that 50mm outrunners are about the smallest you can really use for a vehicle before they start getting too fast (Kv rating too high) to easily gear down. I foresee the 50mm motors being useful more in scooters than anything else, where a low profile helps compared to the chubbier 63mm motors, unless your scooter is the size of a small bus.

But the other reason is that the Democratic People's Republic of Chibikart (Hereafter known as just "chibikart" because why did I pick such a name?) uses them, and on a go-kart where pushing off with your leg is just ruining the point, sensors are pretty critical. I've been at a loss to explain how to add sensors to the motors because there is so much customization involved, so Chibikart was published without sensors, but with the sensor boards and attendant plastic ring things and automagically calibrating controllers, I think I'm getting pretty close to an "official solution".
