1- To send 5 analog channel data to the Bolt cloud using an Arduino nano, you need to connect the 5 analog channels to the analog inputs of the nano.
Then you have to use the boltiot-arduino-helper library (check out the interfacing controllers documentation on https://cloud.boltiot.com/docs). The only change you need to make is in the boltiot.CheckPoll function. Instead of passing only 1 argument you need to send all 5 analog data. The following is a valid instruction line
You can send up to 6 variables to the Bolt Cloud in this manner.
2- Bolt Cloud offers Bolt Cloud API, Using Bolt Cloud API, You can fetch device data from bolt cloud to your server or you can send commands to your bolt device from your server.
