[Arduino

The source code implemented in the live broadcast was uploaded to the blog!

This is an example of mixing Nokkanda's ESPNOW and BLYNK together!
There are two main themes!
1. Send sensor data to BLYNK using ESPNOW!
2. Upload sensor data to BLYNK, but try with low power (deepsleep)
In No. 1, when the board connected to BLYNK is called A and the other board is called B, there is sensor data on board B!
You can implement an example of sending sensor values ​​to the Blink Dashboard by sending them from B to A with ESPNOW!
Conversely, let's implement an example of controlling by sending control commands from A to B to ESPNOW in BLYNK!
In No. 2, there is a sensor on Board A connected to BLYNK!
The A board is supposed to run on batteries somewhere out of the house!
At this time, let's make an example of how to upload sensor values ​​to BLYNK while reducing battery consumption as much as possible!
The concept is that board A boots up, connects to the BLYNK cloud, uploads sensor data, and then activates DeepSleep!
Check if it works well and show the difference in current consumption when it is in deep sleep and when it is not!
And let's output the time when the sensor value is uploaded to BLYNK! (Blink already had such a function built-in)
