Using Visual Studio for python -- back to debugging mode , feels amazing. So finally after managing to get 4 18650 batteries , 2 of them are discharged , now not sure how to recharge them.

Learning about electricity fundamentals. So we need 7v to 12v to power in battery mode. We got a 9v battery just to see if it works, but seems like the current might not be enough. https://www.teachmemicro.com/use-l298n-motor-driver/ http://forum.arduino.cc/index.php?topic=325357.0 https://forum.arduino.cc/index.php?topic=158582.0 https://arduino.stackexchange.com/questions/30595/lipo-batteries-with-l298n-controller https://www.robotshop.com/community/tutorials?mode=list&sort=newest&page=1 So it's final seems , the current provided by the 9v battery is quite less and needs more amps. https://learn.sparkfun.com/tutorials/how-to-power-a-project  https://www.open-electronics.org/the-power-of-arduino-this-unknown/ 18650 Battery https://www.makeuseof.com/tag/difference-32-bit-64-bit-windows/ Now back to Artificial Intelligence USING CURL to DOWNLOAD files http://www.compciv.org/recipes/cli/downloading-with-curl/ For opening Notebook https://azureml...

It has default pins which are used for sensing current and controlling the speed and direction of the motor.

Motor Shield for Arduino motor shield is required for Bluetooth , GPS , GSM and Servo Motor in order to generate a stable and controlled current.  Connecting directly to Arduino board , the equipments may start drawing large current damaging the board. First Experiment with Arduino - LED Test. The RGB LED sensor has 4 points , 1 positive for 5 V connection and 1 each for red , green , blue . Pass accordingly LOW and HIGH to arduino Red , Green and Blue.

Arduino Robotic Kit https://photos.app.goo.gl/Ng6MmaRnxHHWUHpJ6 Just got my Arduino robotic kit , quite excited :-) , Let us start exploring the various components. HC SR 04 Ultrasonic Ranging Module https://www.mouser.com/ds/2/813/HCSR04-1022824.pdf HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm Vcc , Trigger , Echo n Ground  You only need to supply a short 10uS pulse to the trigger input to start the ranging, and then the module will send out an 8 cycle burst of ultrasound at 40 kHz and raise its echo. The Echo is a distance object that is pulse width and the range in proportion https://randomnerdtutorials.com/complete-guide-for-ultrasonic-sensor-hc-sr04/ https://www.arduino.cc/en/Reference/Libraries https://www.youtube.com/watch?v=6F1B_N6LuKw

2 class logistic regression https://docs.microsoft.com/en-us/azure/machine-learning/studio-module-reference/two-class-logistic-regression used to predict only 2 outcomes For  Label column , click  Launch column selector , and choose a single column that contains outcomes the model can use for training. For classification problems, the label column must contain either  categorical  values or  discrete  values. Some examples might be a yes/no rating, a disease classification code or name, or an income group. If you pick a noncategorical column, the module will return an error during training. For regression problems, the label column must contain  numeric  data that represents the response variable. Ideally the numeric data represents a continuous scale for creating web service , all steps need to be run

Based on my friend's request , I have begun to write more on it. So it's been a long time since I have left Data Science in some lurk , but honestly I did struggle a lot to cope up with it. Plus because of timeframes , I scrambled through Data Science initial models , but I couldn't gather a lot except R programming and concepts of Data Science , ML and AI. Data Science seems a tough hill for me , by tough hill I mean way more time and effort , I got busy in work and then somehow , it's been pending , Suprisingly I didn't come across Microsoft Certification Program because that should be the defacto choice for a .Net Developer having spent more than 8 years professionally and 19 years with Microsoft and it's ecosystem. So I began seeing Microsoft Artifical Intelligence course it seems very exciting , although I remember my stint from GCP (Google Cloud Platform ) , it was a big thing doing some things I did very naturally with SQL or Excel. https://www....

Let's keep it precise and small steps. 1. You need Visual Studio 2017 Community or Professional. 2. Select NodeJs development package. 3. You need NodeJs runtime to be installed from https://nodejs.org/en/download/ 4. Start a new project from VS 2017 , TypeScript->NodeJs 5. You might get an error , http or project not found. 6. Check the reference of the TypeScript project. 7. If you see the warning icon indicating that mode reference missing. 8. Right click and click Install from npm. 9. I you receive an error message , just follow the instructions. 10. Specify the node.exe path in the proj properties.C:\node-v8.9.4-win-x64\node.exe 11. Build and voila , let's start.
