When I published my Type4me project, someone wrote me pointing out that the steps to send your sequence of characters to the device were a little complicated: open a terminal emulator (PuTTY…) connect to the correct serial port send the sequence check if the device answers correctly (OK!) For this reason, I’ve just finished the first…
Today’s project was designed to solve the need to enter, using a keyboard, the same sequence of characters (a password, a greeting…) many times.
LEDs with high brightness (high power LEDs) offer a lumens / watt ratio very higher than traditional incandescent or fuorescent lamps: This type of LED has to be driven by a constant current source: 3W LEDs have a nominal current value of 350mA. I designed a module to drive a single 3W LED and to change…
The BTSwitch project was developed to switch electric devices (lamps…) using an Android smartphone. In the following video, you can watch the device working, while in the next pages you can find some technical details… enjoy your reading!
In this third blog post, I’m going to show you the logical view of my Nixie clock and two of its main elements: the real time clock, to keep track of the current time, and the expander, to add more I/O lines.
In this second post about my Nixie clock, I’m going to show you how to drive those tubes with a microcontroller.
The following project was designed for a need: with my friend Davide I’m working on a model railway (Il Plastico di Davide e Luca): we needed to know how much current it uses to size our power supplies (booster)… The sensor For current measurement, I used ACS712 sensor from Allegro MicroSystems (here’s its datasheet). You can find…
A project I’m working on is a Nixie clock… in these posts I’m going to show its development!
ArduRGB it’s a simple project to show how to drive an RGB led with Arduino. In the GitHub repository you can find the Arduino sketch and a sample program written in C# and in the forum you can ask for informations,requests… [highlight color=”yellow”]Warning: the program described below is designed for a common cathod led, if you need to use…
