Later this can be expanded into PCB design. This is exactly how I created the first design. You can start by drawing up the circuit as a 2D drawing, then switch to a 3D view of components to work out how you might connect them. Circuits can be drawn up in Fritzing in a number of ways. The software is highly supported by the Arduino community so most components and shields you can think of are available for it. It’s a simple and cheap program which allows you to make a circuit in a number of different views. To design a quick circuit, I like to use Fritzing.
This gave me some ideas on hardware to use and how to set up the Arduino but didn’t give me everything I needed. For this CAN Bus adapter, my inspiration has come from the blog. Designing a circuit in FritzingĪs I mentioned before, Arduino is so popular, that you seldom have to start from scratch for any project. It’s not a shield in the Arduino format, but I have a solution to that in the form of a breadboard. It comes on a small daughterboard, as above. In this case, I will use an off the shelf TJA1050 CAN Bus adapter. This makes finding suitable hardware easy and quick with just a basic Google. There is a near-infinite range of inputs and outputs available as Arduino compatible shields.
TJA1050 CAN Bus shield with SPI interface Just find a project that’s close to what you want and tweak the settings to match your hardware. The Arduino IDE (programming software) makes checking an uploading code very straight forward, and because of the Arduinos popularity, you seldom have to code from scratch. The biggest advantages to using the Arduino is the popularity and simplicity of the code. I tend to start with the original UNO and scale down to the PRO MINI or NANO. There are a few different form factors of the Arduino microcontroller, offering different features. It’s as easy to use as plugging in hardware modules (called shields), uploading a program (called a sketch) by USB and letting it run. The Arduino is a simple circuit board with everything you need in it to run a simple program. Then I will be able to use standard CAN Bus interface boards, controlled by the Arduino to get information from the network. For this reason, the majority of my electronics projects are based on the Arduino microcontroller. I have to admit to not being particularly keen on programming and like to take the easy way out where I can.
