ESP32 With Arduino IDE

Christmas 2015 yours truly was one of the lucky few in the world to receive the ESP32 for experimenting. The board was not assembled, and it was quite intimidating to assemble the board with just a fine tip solder. The experiment is documented at this URL: https://www.instructables.com/id/Beginners-ESP32-Gu... This afternoon, yours truly came across the Arduino Core for ESP32 on github URL here: https://git ...

LTD SMRT Project (Safe Monitored Rider Transit)

The proposed new LTD public transportation system uses people counters on the bus system to get an accurate measure of rider tendencies across different routes at specific times. Each bus will be equipped with two sensors which will generate numeric data no larger than 4 bytes of memory at any given time. The data will then be wirelessly transferred to LTD headquarters once per minute. Having this informati ...

DIY Low Cost Arduino Mobile Development Platform

I have wanted to build my own robot for awhile now. But after many tried and failed attempts, I was losing hope that may ever happen. I discovered that there wasn't a small, robust, super easy to add-on to, robot that was within my budget to get. After hours of research and many robot kits later, i decided to build one from scratch. This includes building the base and electronics myself. I was always a fan ...

ZIF socket Arduino-compatible board

In this tutorial we make an Arduino-compatible board that holds the microcontroller in a ZIF socket. Updated 18/03/2013 Today we are going to make a different type of Arduino-compatible board, one that has a ZIF (“zero insertion force”) socket. Our reason for making this is simple – now and again you may need to program more than one bootrom with a sketch, for example if you were planning to make your own e ...

How To Make a Simple Variable Frequency Generator Using Arduino

A frequency generator is a very handy device in electronic design, development, testing and trouble shooting. It is such a kind of device which can generate the required frequencies which can be then applied directly to the target device for testing it. There are frequency generators which can generate the required waveform like sine wave, saw tooth wave etc. but for normal applications the square wave gene ...

Lambda Calculus in a Can using Arduino

You can get soup in a can. You can get bread in a can (*). Now the long wait is over! You can finally get Lambda Calculus in a can. Project LambdaCan is an amusing exercise in absurdity. It implements a reducer (interpreter) for the Lambda Calculus, a formal system (programming language) developed by Alonzo Church in the 1930's to attack the deepest mathematical problem of the day. This was the Entscheidung ...

Fritzing – The Ultimate Tool For Sketching Out Electronics Projects [Cross Platform]

Despite sounding like an alcopop, Fritzing is actually an incredible bit of free software you can use to create circuit and component diagrams for use with rapid-protoyping electronics boards such as the fantastic open-source Arduino. As such, it’s open source too, entirely cross platform and well supported – you can almost guarantee that it can be used on any Arduino project to show you how to wire things ...

Compact Protoboard Arduino type thing yea

This ible is for the building of my small, almost matchbox size, arduino compatable board. As seen in this ible.. http://www.instructables.com/id/Pocket-Ardiuno-kit/ I experemented with the one in this ible to see how it can be impreoved, but the consept is the same and so is the build to a degree. Origonally made as a pocket board for taking places with a few components for messing with. Basic specs: - atm ...

Diverting surplus PV Power

As mentioned on the Contents page, two different hardware platforms have been successfully used to support Mk2 PV Routers. [Update at 7/3/14:  Since writing this article, I have developed a new hardware platform which has been specifically designed  for this product.  The main board has an integral power supply and RF module, and there is a display to show how much surplus energy has been diverted each day. ...
