IR sensors for temperature detection are extremely easy to set up and use with our microcontrollers, only 4 wires needed and two of them of for power! If you’re a video kind of person then here’s the accompanying video, otherwise read on below for more textual instructions! Affiliate links Various […]
Video is below, click to view… In this episode I look at a particular type of fingerprint sensor, the JM-101. It goes through how to store fingerprints on the device, how to clear them and how to check for a stored print. Spoiler alert: I’m not too happy with this […]
A video below explaining the reset sequence of the 6502. With a possible “bug” in the chip, perhaps. Source code shown in the video is available below.

Ever wanted to run more than one screen independently? Are you using the excellent tft_espi library? Well this guide will walk you through the small bit of work you need to do to achieve this, in particular with an ESP32 but the principles can be applied to any MCU of […]
OK, so sorry for such a long wait but at the time I started this project I envisaged working on the I2SAudio library (and other projects) far more than I did over the last year. As it happens circumstances have dictated a much lower release schedule for videos and articles […]
Intro In the last article we learnt all about the various pins of the 6502, today we’re going to look at the various ways of supplying a system clock, power up and see perhaps things you were not expecting. The you tube video is below and the main article follows. […]
IntroHere is the venerable 6502 processor, in this series of articles we are going to build a full computer system based around this 8 bit brain. Today we are going to look at the various pins and how we need to connect them to create a basic system. A supporting […]
In this, the last episode on making our own wav player we are going to look at how we can mix multiple sounds together. If you haven’t seen the previous articles in this series then this is highly recommened as they contain circuit digrams and show the other aspects of […]
A detailed look at how to play WAV’s from SD without using 3rd party libraries for transfer of WAV’s to I2S. It should give you enough detail to add this into your own code/wav players. Video Below which goes through everything and sources code/diagrams afterwards. INTROAs always time-codes are available […]
In this article/episode we are going to follow on from the last one on I2S and get our software to play back some music. We’ll look at the WAV file format and how we can get the data out and send it over I2S. If you haven’t read/watched the previous […]
