The site also features the Arduino Online Compiler, which allows you to gather your sketches and compile them. Some, like ArduinoDev, are informal sites where you can connect with the Arduino community through forums and cooperative projects. Not all online tools take the form of software services. The service costs $10 a month with a one-month free trial. You can edit other users’ sketches for your applications or create your own to share on the network. More than 140,000 registered users are on Codebender, so there’s plenty of fresh ideas to inspire you.
