Let’s see how to connect an Arduino to a WiFi network.The Arduino must have WiFi connectivity, for example the Arduino MKR WiFi 1010, which is the one I use, or the Arduino Uno WiFi Rev2 and others.We’re going to use the library WiFiNINA. This library is super handy and lets us...
The ‘does not name a type’ error is an indication from the Arduino IDE that it was unable to find a definition for something that you’re trying to use. The most common cause of this error is when you are trying to declare or use a variable or function that doesn’t exist. For e...
The LED is used to signal that the sketch is recording a gesture If you want to use your own trained data, replace #include "digits_model.h" with your own, then replace const char* GESTURES[] with your own trained gestures Arduino IDE vs: 1.8.12 ...
The other Arduino boards discussed so far use a microcontroller that doesn’t natively support USB, so they have included on the board a separate microcontroller that serves simply as a UART to USB converter. The ATmega32u4 used in the Leonardo and Micro instead includes native USB support elimi...

a USB to TTL 3V3 Serial Cable, it is also possible to program the ESP-01 using an Arduino UNO, usingthis circuit, but don't use the UNO 3V3 power pin as the ESP-01's power supply it is only rated at 150mA and can cause problems when trying to debug a project that uses WiFi. ...
You can connect the PLC to Arduino with the ENC28J60 module. Use a digital output on the PLC to trigger an input pin on the Arduino. Map Q1.0 status to a digital input on the Arduino and handle the communication protocol (e.g., Modbus TCP) in your code. LikeLikedUnlikeReply User17...

WiFi connectivity can either be added directly to the Spresense main board or by using the Spresense extension board together with a WiFi Arduino shield. This tutorial explains how to equip Spresense with WiFi directly to the main board, but the steps after step...
For more details see How to use the UART. Expand all Step 1 Start by downloading this repository: https://github.com/RohmSemiconductor/Arduino We will use the sample in the “MK71251-02” folder. Open the “MK71251-02.ino” sketch in the Arduino IDE and...
