If you read the first article I talked about the requirements of the arcade game Frogger, how we needed a faster processor than the Arduino and also more memory in terms of both program memory (mostly because of graphics storage) and actual RAM. The conclusion I came to was to use the quite cheap but powerful ESP8266 in the form.....

I big thank you for the first person to give a donation on the new Donation link on the right hand side. I really am grateful, every amount donated will go to running this site and building projects. The first person was (only giving first names but they will know who they are) Peter Thank you very much Peter......

Supporting video to the article just below on connecting up a Colour SPI (ST7735 driver) LCD to the excellent ESP32 (NodeMCU 32S version). Click into this post to see the video......

In this article we connect a 128x128 Colour LCD (ST7735 driver and SPI driven) to an ESP32 (NodeMCU 32S version)......

A video is now available supporting this article, click below and/or read on Connecting a colour screen over SPI to ESP32 based MCU's is a straight forward process and is extremely similar to using one with the Arduino or ESP8266. Firstly though you need to ensure that you have set up your ESP32 to work with the Arduino IDE,.....

Up until now I've managed to fund XTronical privately, funding both the server and builds/equipment required. However as it's growing and projected to grow I've started including adverts on the right hand side and small ones at the top and bottom of posts and pages. It really doesn't bring in much at all, but the hope is it will at.....

OK, apologises for this off-topic post, although it is a technology thing I suppose! Just wanted this out on the internet in case anyone else has this issue as I could not find this solution anywhere. Before the Purchase I've been using Sony Vegas 11 Studio for several years and it's been in my opinion an excellent editor with a.....

In this surprising video I look at three USB voltage and current meters (some do additional features calculated from the measured voltage and current) and investigate their accuracy for both voltage and current compared to a decent multimeter. Are they all the same as each other (for good or bad) or are some better than others. I do a full.....

If you wear this project before December then it's wrong, sooo wrong, don't do it - Bah Humbug! On a more festive "past November the 31st note", let's make a bespoke Christmas jumper :) Here's a short video of the final project in action! Kit List  A basic plain Christmas Jumper suitable for modification! Or any plain jumper :).....

In this article we'll look at how to program an ESP32 from the Arduino IDE in C or C++. At the time or writing Espressive Systems (who make the ESP32) have not integrated this board fully into the Arduino board manager so it is a more manual process, don't be put off though as it is extremely straight forward. Just bare.....
