Electronic, 3D printing and embedded programming
In this tutorial I explain how the IoT core, through AWS services, can communicate with our devices. In particular, let’s see the use of the MQTT protocol.
Now let’s go through the esp8266 connection steps.
To help with fast prototyping, I’m going to create a set of shields for the WeMos D1 mini. The shield of this article manages the EBYTE LoRa device (E22, E32 and E220) with HardwareSerial, already exists a variant with SoftwareSerial.
In this article, we’ll understand the security system used by Amazon, with a certificate, to connect our device via MQTT.
To help fast prototyping I’m going to create a set of shield for WeMos D1 mini, the shield manage a 3.3v relay with configurable pins
NodeMCU v3 high resolution pinout and specs
For fast prototyping, I will create a set of shields for the WeMos D1 mini; the first is a service board with integrated pcf8574 IC, an encoder, and five other pins to use as input or output.
In this series of article about firmware and how to update It, I’d like to add a series of alternative methods of updating that are very useful for me.
In this article, we will learn how to add an FTP server to our device and use It to upload firmware and filesystem updates.
In this series of article about firmware and how to update It, I’d like to add a series of an alternative methods of updating very useful for me.
In this article, we will learn how to use external storage like the SD card to update firmware and filesystem.
OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi connection rather than a serial port.
In this article we are going to explain OTA update via HTTPS secure connection, and with a valid self signed certificate trusted from the client.
LineaMeteoStazione is a complete weather station solar powered which can be interfaced with professional sensors from Sensirion as well as some Davis Instrument components (Rain Gauge, Anemometer) It also can be interfaced with a...
