Continue reading →: Using older Noritake Itron VFD modulesNow and again you come across interesting parts on eBay, from friends or just rooting around in second-hand stores. One example of this was a huge Noritake Itron 40 x 2 character vacuum-fluorescent display from 1994 (or earlier) which was passed on from a client. Originally it looked quite complex,…

Tutorial – Arduino and PCF8563 real time clock IC
Published by
on
Continue reading →: Tutorial – Arduino and PCF8563 real time clock ICAnother option for real-time clock ICs is the PCF8563 real-time clock IC from NXP – so this is a tutorial on how to use it for time, date, alarm clock and square-wave generation purposes. The PCF8563 is another inexpensive RTC that can be used with an Arduino or other platforms…

Now and again there’s a need to expand the I/O capabilities of your chosen microcontroller, and instead of upgrading you can often use external parts to help solve the problem. One example of this is the 74HC4067 16-channel analog multiplexer demultiplexer. That’s a mouthful – however in simple form it’s an…

Continue reading →: Tutorial – Arduino and the TI ADS1110 16-bit ADC
Moving on from a previous article where we explained an 8-bit ADC – in this instalment we have the Texas Instruments ADS1110 – an incredibly tiny but useful 16-bit analogue-to-digital converter IC. It can operate between 2.7 and 5.5 V so it’s also fine for Arduino Due and other lower-voltage…

Tutorial – Arduino and MC14489 LED Display Driver
Published by
on
Continue reading →: Tutorial – Arduino and MC14489 LED Display DriverAs an increasing number of people enjoy experimenting with retro-hardware and electronics – especially stuff with numerical LED displays – they have discovered the classic MC14489 LED display driver. The MC14489 (originally from Motorola) can drive five seven-segment LED numbers with decimal point, or a combination of numbers and separate…

Continue reading →: Project – Scrolling text clockThe purpose of this project is to build a scrolling text clock that displays the time as it is spoken (for example, “it’s midnight”). This is a quick project – we give you enough to get going with the hardware and sketch, and then you can take it further to…

Continue reading →: Arduino and KTM-S1201 LCD modules
After looking for some displays to use with another (!) clock, I came across some 12-digit numeric LCD displays. They aren’t anything flash, and don’t have a back light – however they were very cheap. The purpose of this tutorial is to show you how they are used with an…

Continue reading →: Arduino and TM1638 LED Display ModulesIf you need a fast and easy way to add some user input and output to a project, these display modules are interesting and fun. They contain eight 7-segment red LED digits, eight red/green LEDs and also eight buttons for user input. The units can also be daisy-chained, allowing up…

Tutorial: Arduino Port Manipulation
Published by
on
Continue reading →: Tutorial: Arduino Port ManipulationIn this article we are going to examine Arduino I/O pins in more detail by using “Port Manipulation” to control them in a much faster manner than using digitalWrite()/digitalRead(). Why? Speed! Using this method allows for much faster I/O control, and we can control or read groups of I/O pins…
