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 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.
