A quick rough and ready one take video of a solution to a problem I had when I had several components on my board and a “as delivered” ILI9341. Until the extra components went on everything was fine, then it wasn’t…. Here’s my solution to the problem.
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 […]
E-Paper (or E-Ink) displays are remarkable devices. They require very little power when up-dating and no power at all once updated. The also provide a paper like contrast and clarity. Which is why they were adopted by e-readers a long time ago. Here we look at hooking them up to ESP32’s.
Using one of these screens with an ESP32 is very easy and requires little change over using then with an Arduino except that the connections are different. This article should be used in conjunction with the video below. The ConnectionsThe SDA connection goes to pin 21 and the SCL to […]
If you haven’t read the previous article (part 1) then I suggest you follow this link otherwise this write-up won’t be of much use! In the last article we got the screen and the MAX30100 pulse/oximeter up and working. In this one we’re going to add everything else! A video […]
This article supports a video on the build of the Star Trek Sick Bay project (external you tube link). You should watch that video as well as this article as it contains information not mentioned below. This is part one of a two part write up. Doing all this on […]
A build of a working original Star Trek display with real sampled heart beat sound. Uses various sensors to get the readings from your body (via just your fingers) and displays them in the style of the 60’s sick bay screen. This bare “Bones” system could be built into a […]
Video and small article on how to connect up cheap (none brand) ILI9341 TFT LCD displays to your Arduino.
In this project we build a type of radar system using sound, a “Sodar”. It implements the traditional “sweeping” display using an OLED display. Click to discover more!
256×320 colour LCD screens are widely and cheaply available and very often come on a board that we can connect up to an Arduino Uno (and some other boards types). It’s then just a simple manner of adding the required libraries and trying out an example. This is all we […]
