ESP8266 NodeMCU Backdoor uPWM hack for IR signals

Wednesday, July 6th, 2016

The AnalysIR crew has published an article showing how to achieve accurate PWM for Infrared carrier signals on the ESP8266 NodeMCU: Quite simple really – just set the baud rate to 10 times the desired Infrared carrier frequency and send a ‘magic’ 8 bit character to achieve the desired duty...

Running NodeMCU on a battery: ESP8266 low power consumption revisited

Thursday, June 9th, 2016

Tinkermax shows us how he reduce the current consumption of his v2 NodeMCU in deep sleep to < 50μA: Unfortunately, with all this added convenience comes the drawback of added power consumption, which continues even when the ESP8266 is in deep sleep. I measured 18mA to the NodeMCU board while...

Soldering iron + Nodemcu = IoT device

Friday, September 4th, 2015

Vegard Paulsen blogged about his soldering-iron #IoT project: My trusty old soldering-iron recently got an upgrade! With the help of a NodeMCU. a RGB-LED it now reports the set temperature to the #IoT Thingspeak.com server through WIFI. It also sends me Prowl messages on my Iphone when I forget to...

ESP8266 running NodeMCU as a controller

Wednesday, April 1st, 2015

jscottb over at LetsMakeRobots writes: My goal for this mini project is to create A simple autonomous rover with just the ESP and NodeMCU. In looking at the specs for node most of the supporting libraries already written. GPIO, PWM and Timer libraries are included in the Lua interpreter. After flashing...
