If you have an Arduino-controlled project that could benefit from displaying data on a large screen television or monitor, then a solution will usually require a HDMI interface to the display. However the Arduino itself can't do that, however by communicating in serial with a Raspberry Pi you can use it as an interface to solve the problem. The process is described by the Code and Life website who have a solution which allows an Arduino to send serial commands to the RPi running pyserial which are converted into graphical units.
Although it's a simple demonstration it gives you the framework to expand and create your own custom displays. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
When connecting 5V devices such as an Arduino to 3.3V device such as a Raspberry Pi, you'll need a logic level converter - and we've got you covered with our LEVEL:.
This module easily connects different logic voltage levels together for bi-directional communication on up to 4 channels, allowing you to use low-voltage sensors or development boards with a 5V microcontroller. It's one of our growing range of useful modules - so check out the full range today.
