Electronic, 3D printing and embedded programming
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
In this chapter we are going to wake on radio the LoRa E32 and microcontroller and we show the shield created for this device.
When you use a microcontroller an important features is store data, for logging or setting, for a web server or to show image. The better solution is an SD card, because It’s simple, small and low power device.
Now we are going to look how to connect and use with standard SD library with Arduino and esp8266.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
In the last chapter we are going to send complex structure.
When you create a new IoT project probably you need to connect microcontroller to a battary power source, but if you don’t use a power saving options your battery will run out in no time.
As a lot of IoT microcontroller, WeMos D1 mini have some power saving mode.
The types are modem sleep, light sleep and deep sleep.
Here is a tutorial on the E32 LoRa (Long Range) device’s very cheap and long-range (from 3Km to 8Km).
Now we are going to understand the various transmission type
Here is a tutorial on the E32 LoRa (Long Range) device’s very cheap and long-range (from 3Km to 8Km).
It’s time to understand the configuration.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
Here my library to simplify the complex usage.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
Start with specs and basic usage.
When I’m going to hang a picture the first problem is if I have a pins, this little tool help me to do a good job, but when I need they, never I can find they.
My solution is to reate a similar tool to print in 3d.
WeMos D1 mini have 2 UART, one on dedicated pins and a transmit-only UART that can be enabled on GPIO2 (D4), It’s very usefully for debug.
