I had been doing lot of experiments with Arduino type boards, I wanted to explore more capable boards with Camera interface to build machine vision use cases. It
We have already seen how to connect Arduino UNO with NodeMCU/ESP8266 over UART and send data to MQTT broker here. That project uses lua to program the NodeMCU
We can program NodeMCU (ESP8266) in several ways. Most of the times I use it with lua (with nodemcu firmware inside it). We can also program NodeMCU hardware
Introduction: Often times, in IoT field, one has to use multiple languages – C++ at edge, node.js javascript at server side, and android/iOS/Web for frontend development. Earlier we
We have already seen how to connect arduino uno to NodeMCU (ESP8266) here . In this blog we connect Arduino UNO with ESP32. When connecting UNO with nodemcu we
C supports pointers to functions. Functions are not variables but you can define a pointer to a function. The function name refers to the address of the function
Johnny-five is a java script frame work which allows nodejs apps to talk to the hardware such as Arduino ,Intel Edison and Raspberry Pi. For full list of support
NodeMCU is great for connecting cloud and arduino is great at talking with different sensors. nodemcu has only one analog pin. In this blog we will see how
