![]() What we want achieve is to compile ddcutil so we can issue terminal commands to change the brightness on the external monitor, eg: just like pressing the buttons on the monitor but in this case the software controls these actions.īefore heading down this path make sure your monitor supports this feature DDC/CI. I ended up using the below command in my automatic start up script: fbi -a -u -noverbose -blend 1000 -t 60 /home/pi/pictures/* This should cycle though your jpg images, changing every 5 seconds. All these command line options can be found in the reference material at the bottom of this step.įirst navigate into the pictures directory on the Raspberry Pi: cd pictures Now is a good time to test to make sure that fbi is working and to start experimenting with the command line options. scp C:/Users/username/OneDrive/Pictures/wallpapers/* will prompt you for the Raspberry Pi password, then it will copy everything over from the folder specified.įYI: later in this guide we will set a static IP address if required. Now on your Windows PC, from the command prompt you will need to enter in a command similar to the below, using the path location where you saved your pictures to and the IP address you got from the ifconfig step above. First you will need to know the IP address of Raspberry Pi, so at the terminal type: ifconfig It's easy to move files from your Windows PC to your Raspberry Pi using the command scp on your windows machine. to list the files and folders that are in your current director you need to type: ls.to determine the location of the current directory type: pwd.Let's make a directory/folder, I was still under /home/pi so I typed in: mkdir pictures Once that is completed we need to install fbi.Īt the terminal enter: sudo apt-get install fbi The "sudo" part of the command allows you to run programs with security privileges, as with "Run as Administrator" in Windows. Let's now update the Raspberry Pi OS. At the terminal enter: sudo apt-get update & sudo apt-get upgrade You should also have network/internet access if you entered in your Wi-Fi details earlier. The default username is "pi" and the password is generally the one setup in Raspberry Pi Imager earlier under ssh. Once you get to the login screen enter in your credentials. Raspberry Pi 3 + power supply (Official)Ĭonnect the Raspberry Pi up to your keyboard, monitor and power.Small wireless keyboard and mouse combo.Hardware that I could have done without, but used anyway Plasterboard Masonry Wall Hook - 5 Pack.Ramset Super Wallmate Toggle Anchor (Hollow Wall Anchors).x2 Pine Dressed Standard Grade 42X19MM 1.2M.SanDisk 32GB Ultra microSDHC UHS-I Memory Card.Micro USB cable (to power the unit from the monitor).3pc Heatsink Kit for Raspberry Pi 4 (I only used the 1 Heatsink for the CPU).fbi software could be launched from Terminal, so there was no need for an OS GUI.PiicoDev sensors were used as they offered a near plug and play usability.The monitor needed to support DDC/CI for brightness control over HDMI, provide power to the Raspberry Pi via USB (less cables up the wall), and having an ultrathin bezel made building a frame a lot easier.Using the existing VESA mounting brackets on the monitor to attach to the wall meant I did not have to engineer a frame that would have to support the monitor's weight.Mounting a dismantled laptop into a picture frame was a nightmare, having to access ports was another disaster, etc Previous attempts to build a digital picture frame from a laptop failed miserably.I come from a Windows OS background so my Linux expertise is minimal There were a number of lessons learnt in getting to the final project build. Wallpapers thanks to: L'Outlander - City On A Hill, provided by Lofi Girl Why I built it this way I have also included a section at the end of unsuccessful software choices if you are considering other options in this space. ![]() I have written the instructions in a modular way so that you only need to complete the parts you require, for example, the light sensor, touch sensor and frame are optional. Lastly, I expanded the project with a touch sensor to safely shutdown the Raspberry Pi and provide additional functionality. It also incorporated a light sensor that adjusted the brightness of the monitor depending on the brightness of the room. The project was built on a Raspberry Pi 3 Model A+. I concentrated on setting up the computer/software side first before building a wooden frame and mounting the monitor to the wall. It needed to be easy to build and operate smoothly. The idea behind this project was to build a large digital picture frame at a lower cost than the ones you could purchase.
