Blynk Makes It Easy to Create Mobile Apps for Arduino or Raspberry Pi Projects
Android / iOS: If you want to control a device connected to a Raspberry Pi or Arduino from your phone, you usually need to know at least some programming skills. Blynk is an app that makes it easy to control these devices from your phone.
Blynk uses drag and drop widgets to help you manage different parts of your electronic projects. This could mean LED values, servo speed, or just checking various data. You can use the service for free, but you will need to shell out some money if you want to make your apps publicly available or use them on many different devices. That said, most of us should like the free plan, at least to begin with. If you’ve ever wanted to connect your various electronics projects to your phone, but had no trouble building an app, Blynk can help.
