Arduino VFD Display Clock Tutorial – A Guide To VFD Displays

Do you (still) remember the display of your old CD player, HiFi system or car radio? Have you ever noticed the displays used at your local supermarket that shows you the scanned item and the price of it? These displays have a characteristic beautiful bright blue-green colored glow in common: These are so called vacuum fluorescent displays (VFDs) with outstanding brightness that look pin sharp. Used to repla ...

OLED displays for still better prices!

The most advanced display technology – OLED, goes ahead into many industrial products thanks to its advantages. From a certain point of view exactly the industrial environment properly checks features of displays and especially in critical applications extreme thermal resistance a big advantage (immediate response even in frost). As it uses to be, new technologies are rarely cheap. In case of OLED we can sa ...

Temperature Display Using LCD

Here is a Simple Temperature Display Circuit using LCD (Liquid Crystal Display). For Heat Sensor we have used IC LM35 (Precision Centigrade Temperature Sensors) whose Output voltage is linearly proportional to the Celsius (Centigrade) temperature. Output of LM35 IC is 10mv/degree centigrade for eg if temperature is 35 degree, then the output of sensor will be 350mv or 0.35V For working with LCD it is necess ...

Flexible graphene-based LED clears the way for flexible displays

Researchers from the University of Manchester and University of Sheffield have developed a new prototype semi-transparent, graphene-based LED device that could form the basis of flexible screens for use in the next-generation of mobile phones, tablets and televisions. The incredibly thin display was created using sandwiched "heterostructures", is only 10-40 atoms thick and emits a sheet of light across its ...

Arduino 7 Segment LED Display and Counter – Tutorial #8

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can be powered from a standard 9V PP3/6F22 battery, or from any suitable Arduino power adaptor.The seven segment display is infact a very simple d ...

Arduino Clock using Standard Clock Display

This is a relatively simple clock to build, in terms of the hardware required and in terms of hooking up all the wires. The complexity lies in the software, which I've conveniently included as part of this instructable :) This instructable illustrates a few things: * Keeping relatively accurate time on an Arduino without using a real time clock (RTC) * Using a basic clock display - the type you see on most ...

DMM provides numerical and graphical displays

The DMM (digital multimeter) is a basic measurement tool for nearly every electrical engineer and many other engineers. With the push to constantly improve power efficiency in electronic designs comes a need to not only measure voltage and current, but to dynamically see them as well. Keithey's DMM7510 combines a 7½-digit DMM with an 18-bit, 1 Msample/s digitizer, which lets you see measurements both numeri ...

Add a TFT Display to your Arduino projects (1.8 TFT SPI 128×160)

In all my arduino projects I was using cheap 1602 LCDs mostly because… they are cheap but also of the libraries flexibility.  Recently I found a nice TFT 1.8 inch 128×160 in a very competitive price and i thought to give it a go.  Just $4.5. I had a little bit of trouble to make it work because you need to use a specific version of UTFT.You will find all the files at the bottom. Connection is easy enough ju ...

Arduino car LCD display

Here is a project I made a couple of years ago for my father’s car. The original dashboard’s info-panel which displayed current time, date and temperature was working only partly – and that only after a good cleaning and connector fastening. In other words – it wasn’t really usable, so I made an Arduino replacement. The new panel features: Big 8-character LCD display with auto-on adjustable white backlight ...

Rally Gearshift Display

This device was built at Recursive Software Development Labs in order to be mounted on a rally car competing in the Estonian National Rally championship. The racing team needed help realizing a reliable measurement device which would output the currently inserted gear on a large, bright led display. The biggest challenge to overcome was that the existing mechanical sequential gearshift would only allow enou ...

Double RC servo tester with OLED display

This is something I’ve already worked on but was never really happy with the result, mainly because the potentiometre that I used was of poor quality and hence non linear and “jumpy”… The problem is simple: I need to have a reliable and easy to use servo tester, that I can use to test/play with a standard RC servo or ESC or anything else that uses the same control protocol. This necessity has arisen again q ...
