(a) connect the RX and TX pins of the ATmega328 and the ESP8266 with jumper leads. I understand you were able to communicate between the ATmega328 and the ESP8266. I did set the dip switches to 1-2 On 3-7 Off to connect the ESP8266 to the ATmega328. I found a tutorial that loaded a sketch onto the ESP8266 that suppose to read a DHT11 and then send it out to favoriot, it did send numbers out out to favoriot, but it was unable to read the DHT11 sensor, it just read "0" ( GitHub - LintangWisesa/RobotDyn_UnoWiFi_Favoriot: A simple IoT experiment, using a RobotDyn Uno+WiFi board to monitor MQ-2 & DHT22 sensor, via Favoriot IoT platform. I want to read sensors attached to the pins and then send out the data to the internet (e.g. I can load scripts onto the ATMega328 to read a DHT11 temperature and humidity sensor. I can find sketches to put on the ESP8266 to connect to the internet and send numbers to Favoriot web page. I just purchased the Robodyn R3 Uno wifi.
To see what is transferred to Arduino from ESP: 1, 2, 5, 6. To see what is transferred to ESP from Arduino: 1, 2, 3, 4. To communicate between Arduino and ESP you will need to activate deep switches 1 and 2.ĭon't forget to change board options before uploading when switching. I am sending JSON objects to reed them by each others in TX and RX. Serial.println("Failed to parse config file") JsonObject& root = jsonBuffer.parseObject(jsonString) JsonObject& root = jbuffer.createObject() Serial.println("parseObject() failed")
JsonObject& root = jsonBuffer.parseObject(json) Note: The Arduino UNO WiFi Rev2.0 board comes with a nice transparent plastic base to protect it.All is ok after a lot of searches I finally did it, I con now communicate in both directions between esp and arduino.
Note: You might need a USB B Cable to load program and also power the board :) Simply connect it to a computer with a USB cable or power it with an AC adapter or battery to get started. It contains everything needed to support the microcontroller. The Arduino UNO WiFi has 14 digital input/output pins-5 can be used as PWM outputs-6 analog inputs, a USB connection, a power jack, an ICSP header, and a reset button. The Wi-Fi Module is a self-contained SoC with an integrated TCP/IP protocol stack that can provide access to a Wi-Fi network, or act as an access point. It incorporates a brand new 8-bit microprocessor from Microchip and has an onboard IMU (Inertial Measurement Unit). The Arduino Uno WiFi is functionally the same as the Arduino UNO Rev3, but with the addition of WiFi/Bluetooth and some other enhancements. This is the latest Arduino UNO WiFi (Rev2.0) from ! Yes, all the way from Italy.Īdd this board to a device and you'll be able to connect it to a WiFi network, using its secure ECC608 crypto chip accelerator.
