So I’ve been looking into this a little more. I took your guys idea of using the TLC5940 LED Driver. So now I’m asking for some help again. I figured 1 long question that eventually solves this is better then a bunch scattered throughout stackexchange. Now comes the wiring part. I’m using an arduino wiring […]
What Are We Doing Here? In an earlier post I described how to use the py-gaugette library to drive an Adafruit 128×32 monochrome OLED display from a Raspberry Pi, and a followup article added high-quality fonts. I’ve now updated the library to run on the BeagleBone Black and to support Adafruit’s larger 128×64 display. On

Setting up your Pi for GPIO programming You need to install a few things to get Python to talk to the GPIO pins and control them. If you’re using the standard Raspian OS, it’s an easy affair. Fire up your terminal if you’re in the GUI and run these commands to install what you need:

While Adafruit’s builders have built up a reputation for constructing very cool and original 3D printed toys, perhaps the most impressive of all their designs was the 3D printed Raspberry Pi Mini Computer, an actually working and customizable pc housed in a 3D printed structure. To refresh your memories, this very cool construction involved a

To this effect a LED, resistor 330 ohmnios, Wire, and protoboard, or tin and a soldering. Also need our Raspberry tenga yes Raspbian preinstalled, if not your case, you can see how to do it in the following link directory. Mounting the circuit You can solder directly LED the wire and resistance as you will

A 7-segment display is a great way to display numbers using your Propeller. You can find these in many products that need to display numbers in a simple way, like clocks, kitchen appliances, or digital scales. This display uses seven LEDs arranged in a special pattern that makes it possible to show any number from

As part of my Big Trak refurbishment (not going as well as I wanted it to), I decided to use the Adafruit Prototyping Pi Plate to mount the additional electronics on. If you’re not familiar with it, then this is it: So it’s a double-sided PCB with a GPIO connector tracked to various pads round

The max7219 lets us control lots and lots of LEDs using just a few Raspberry Pi pin-outs. No hassles with multiplexing, latching, refreshing or using up all your outputs – it handles everything for us. We just send commands to the max7219 and we can control up to 64 LEDs or eight seven (8 including

Do you know how many devices are on your local network? That is what we where wondering at our hackerspace HackBergen. Yes, there are available programs and Apps to scan your network, but we can also scan with the Raspberry Pi (RPi) and show the result on a set of 7-segment displays. These look cool,

The easiest way to turn on an LED using the Raspberry Pi is to wire it up to the +3.3v or +5v pins of the General Purpose Input Output (GPIO) header and ground (0v), making sure to place a resistor in series with the LED and ground. Bear in mind that It is important to
