This is a full tutorial for connecting up the PCM5102 or MAX98357A I2S decoder DAC’s. With the demo’s being how to use them for Internet Radio. It also includes a explanation of what I2S is and how it functions. I will build on this in future episodes which will show […]
The ILI9341 is a great display, fast, cheap and most modules for hobbyists come with an on-board SD Card reader and built in touch screen – marvellous! But getting all these things working, especially with the ESP32 has sometimes been a little hit and miss – if you trawl the […]
How to solve the out of memory error when compiling for ESP32. This will occur even when you’ve only used 1Mb of memory and you should have up to 4Mb! If you’ve seen other solutions and they didn’t work for you then try this – as I’ve had the same […]
In this video and article we look at how to log temperature (you could expand this for other sensors you may have) onto an SD card in a format suitable for direct opening in Excel (and probably open office too or other available packages). Here’s the video, the circuit diagram […]
A video with everything you need to know has been published below, the circuit diagram (if you need it) is at the bottom of the article which ises the connections used in the video. SD cards are incredibly cheap (around the price of a normal size chocolate bar), yet for […]
The video covers using PIR (Passive InfraRed) sensors with an Arduino. These are simple movement sensors and although libraries are available they are not required to work with these devices. The sample code shown in the video is shown below.
Which is better? Fake Lego Motor or Real Lego Motor – Let’s find out. Power Functions “M” class. Let’s find out which is better, fake lego “M” motors or real? In this video I go through a series of tests to find out
My humble review of 2019, showing favourite/popular/ unpopular videos. Nothing else to be said!
This project will allow an ESP32 to access online weather forecasts for display on an E-Paper display, running on batteries with an always on display. Cheap Lithium Ion batteries will give around 1.5 to 2 weeks service, better quality or better capacity will give you potentially several weeks. The video […]
