Project update 4 of 8
BlueIO832 Mini is a powerful device that allows you to do a lot without needing to write a single line of code. Today, we will show you how to capture data from its three analog and six digital pins using the BlueIOSigCap mobile app. This data will be sent to the app in real time for visualization and storage.
Follow the instructions below and have fun with your device!
You will need to send analog and digital signals to BlueIO832Mini, as shown in Fig. 1 below.
