There are two parts of programming in this Smart Water Monitoring System using IoT. In the first part, Arduino is programmed and in the second part, NodeMCU will be programmed. Complete code for both ...

Be aware: Input voltage range of bare ESP8266 is 0—1.0V. The operating Voltage is 3.3V. Therefore the NodeMCU (v1.0) has a voltage-divider circuit at Pin A0. If you have a different Board-Setup please ...

The Inter-Integrated Circuit communication protocol works in 2 modes ... In summary, This project shows how the Arduino uno and the ESP8266 or nodeMCU communicate via I2C protocol. The nodeMCU as a ...

Since we are using the Circuit Digest SMS API ... As I previously said, we want to install an Arduino IDE on our PC. After that, we want to download the NodeMCU ESP8266 board support package from the ...

Let’s now start writing a program for ESP8266 NodeMCU using Arduino IDE. (Some basic knowledge of microcontrollers is required, otherwise some terms may be confusing.) To write programs for ESP8266 ...

Circuit operation is done using the software program loaded into the internal memory of NodeMCU. Arduino IDE 1.6.8 is used to compile and upload the program. Software Blynkrobo.ino is written in ...

In upcoming articles, I will adapt new design ideas to implant NodeMCU at the heart of fascinating IoT systems. See you all in succeeding projects. Did you know? It’s very easy to use the Arduino IDE ...

the idea is that he can still use the Arduino to reprogram the NVRAM chip when he wants to play around with the sound. We’ve covered some pretty fancy circuit bent instruments here in the past ...
