This is my work in progress ~50cm
Robotic Arm with 6 AXIS Servo motors, an Arduino and a RaspberryPi ( for image recognition in phase 2):
While writing the C++ code in Arduino I found I needed a way to send easily and fast commands to Arduino with my iPhone using Bluetooth.
Basically I need to control my robotic arm using an external device instead of running and running again the code on the Arduino board.
For this reason: I’ve attached a BLE board to Arduino and I have created a simple app (completely written in
SwiftUI 😍😎) that use BLE connection to connect to Arduino BLE board and send string commands that are parsed and executed.
Commands sended are like:

Very often a lots of iOS applications use your gps position to retrieve data or to lock / unlock contents positions based.
With Android you can use lots of apps called
Fake GPS or similar that allow you to change your real gps position with a mocked one.
On Android development side this can be blocked checking via code the:

I want to share a way to draw in
Unity3d editor a cubes based grid that allow you to snap objects in the same position and make a cube grid, like this:

Every time you upload a
screenshot on the App Store for a new app submission, you receive from Apple this error message:
“Images can’t contain alpha channels or transparencies.”

Very often you create a
new class or a new view controller and customize it before start coding.
Every time you select from
XCode, New File, the file type and add it to your project, like this: Continue reading “Create your own XCode template”
I have bought a new weight scale that works with or without a smartphone.
There is a proprietary app, called
Laica Body Touch.
Problem with this app are:

Why this guide?
My need was to control the robot asking simple commands through
Google Home and Alexa like: “ Alexa, clean the bathroom“.
With my robot, this was not possible. With the app, you can configure the zones but you can’t simply ask for cleaning only one zone, two times, for instance, all in automatic.

For personal purpose, I need to know the number of followers, likes, subscribers, etc…
The examined social platforms are:
Facebook (number of likes) Instagram (number of followers) Youtube (number of subscribers) Twitter (number of followers)

In my personal case I use three different git services for store / share my personal / work code:
Github // my blog code, free open sources code Gitlab // my work code, on-premise installation Bitbucket // my personal code, free private repo
Every service uses
different SSH keys to use. Must be configured separately. Continue reading “Use multiple GIT accounts on same machine / macOS”
