In this tutorial we will show how to write to and read from NodeMCU using SPIFFS(Serial Peripheral Interface Flash File System). We will write temperature data from DHT11 sensor into the flash memory file system using SPIFFS. Then we will read the s…
Here DC motor control using ESP12E WiFi module is illustrated. The DC motor is controlled using PWM from ESP12E via web page. The web page contains a slider range which can be varied for PWM range. This makes it possible to control a dc motor from …
Here a simple ESP12E WiFi module based Wireless digital voltmeter is illustrated.The ESP12E is used to detect voltage using it's analog to digital converter pin. Using this ADC pin we can sample voltage and send the voltage data to PC or Mobile…
In this ESP8266 tutorial we show how to use PWM(Pulse Width Modulation) of ESP8266 WiFi chip to control the brightness of a LED via software and using potentiometer . We will use ESP12E module which is a module version of ESP8266. There are various…
