Serial Display for Arduino is an Android application developed by JOJOAGOGOGO. It allows users to display the Hardware Serial output of the Arduino to their Android device. The main purpose of this app is to provide an easy way to debug during operation and development. The configuration is simple and does not require any difficult setup. However, it is important to note that Android devices must support the USB Host API for this app to work properly.

The app offers several settings options, including the ability to set the Baud rate, enable automatic scrolling, and prevent the screen from sleeping. It is compatible with Arduino Uno and Arduino Nano boards, as well as Galaxy S4 and Galaxy S6 Edge devices.

Please note that in some cases, the power supply of the Android device may not provide enough voltage, so it is recommended to supply power to the Arduino separately if needed.
