Code Post - Interfacing Arduino and Python

This is something I've done by hand at least ten times and always seem to lose it so I've decided to post it here. It is an easy way to debug and test stuff will developing software for the Arduino (or any Microcontroller really). There is a python code that sends string messages to the arduino over serial based on which arrow key on your keyboard is pressed. There is also an Arduino code that listens for these messages, then repeats the message back to the PC to make sure it went through.

Hi guys, Just wanted to make you all aware of a new project that is going to be released on Kickstarter on the 16th May.  Read more

Shipping

I've been setting up my profile for selling on the marketplace and am wondering if there are any seller settings or tables to use for adding shipping classes. 

For now I've included shipping costs into the price. 

Thanks!

ESP8266 running NodeMCU as a controller

Every since the ESP8266 modules were released, I have wanted to try one.  I ordered a few once they came out last year, but did not get to try them out until this year. After trying one module that seemed to work but never could be connected to, I tried another and was finally able to get one to work. The only test I actually did with it was to grab a webpage, basically a curl call. That was earlier in the year and had done nothing else since with them.

ESP8266 wifi module issues I have had

The ESP8266 is very powerful little module, but a very picky one as well. In working with original ESP-01 I had very limited success with it and it just acted "flakey". I do understand now what most of the issues were with this module.

Problem with HC-SR04 distance sensors

Hi Everyone,

I have been finding that I get erratic distance measurements on my tests with the HC-SR04 sensors. I put together a circuit with 128x64 OLED SSD1306 I2C display (Really like that module, by the way) connected on a breadboard to Arduino Nano v3.

The idea behind the circuit is:

Use the NewPing library to generate a distance measurement in centimeters.

Print the distance value to the screen, and keep on repeating.

As the sensor is moved around (8V lipo battery connected to Vin and Ground) you can see the distance updated on the tiny screen.

Help with power circuitry

Ok so followng the advice in this thread and from these forums I have now bought a 7.4v and an 11.1v Turnigy LiPo rechargeable batteries (different voltages to be used in different applications).

Mega blocks - DRC seeker working...

Well.... I set myself the task of creating a robot that would learn an object then go and find it using vision....

Mission accomplished.... well, its probably not very robust but that's a problem for another day...

Today's task was the Mega Block challenge -  an area bordered by Mega Blocks (it's what the kids use and have quite detailed images on them that I can use as objects to find):
