Our next goal would be to establish communication between Luminardo and ELM327 OBDII Bluetooth adapter like the one shown on the picture below. The adapter allows not to interfere with wires and therefore eliminates (or at least minimises) chances of running into problems with car’s onboard electronics, however, Bluetooth link adds up an additional complexity […]

One of the most attractive features of Luminardo is its USB Host functionality built around MAX3421E chip and amazing USB Host Library for Arduino written and maintained by TKJ Electronics and by Circuits@Home. Today we are going to compile their library for our Luminardo and try to run a ‘quality test’ to make sure that […] Flashing bootloader is probably first priority task following immediately after PCBA soldering and assembling process. A board with bootloader in place significantly simplifies firmware development process, allows not to be dependent on presence of external ISP programmer (such as USBTinyISP). It also allows for seamless integration with well-known and very popular Arduino IDE As a […] Luminardo was specifically designed to work together with Vacuum Fluorescent Display (VFD) panels such as MVFDPanel 16S8D. One of the most distinctive features of Luminardo is its low profile. The board also shares same dimensions with VFD module so the final product looks very compact and unusual, it could be easily embedded into a car […] With MVFD Panel requiring substantial amount of pins it becomes really first priority to minimise the number of GPIO and processor’s resources for some projects. That is where MVFD Serial Backpack comes to play. It takes responsibility of communication with VFD panel and conveniently provides either I2C or Serial interface to the main controller. Very […] Inspired by the success of VFD MagiClock a decision to make something similar but out of new parts was made. To be fair, despite its appealing look the original clock was assembled using scrapped parts making it really difficult to replicate. In addition to that, rather substantial dimensions and necessity to have cumbersome power supply […] These days LCD modules become cheaper and cheaper and finally they are getting to the point when it is practical to use them for hobby projects without substantial budget increase. Not only projects significantly gain in functionality and usability but also in aesthetic matter. So we decided to test one of these LCDs and have […] The whole process from initial design to final assembling is presented in this video. We aimed to make it alive, entertaining and easy to watch. Hope you will like it! Now when we have full control over VFD display, it is time to build something meaningful. How about remotely controlled clock with temperature sensor? Boring? Well, it will be unusual device: capable of working from virtually ANY type of remote control, with display activated by a motion sensor, with capability to log current temperature to […] In order to control DP501 HNV-07SS61 VFD in an effortless and efficient manner the following software driver has been implemented. The functionality is encapsulated in HT16512.cpp and HT16512.h files and designed for AVR processors. To drive communication interface the logic uses PinMode and DigitalWrite functions provided by Arduino low level library. Also new HT16512 class […] |
