Sketch and wiring for Arduino can be found here. I connected ESP's GPIO0 to RTS and GPIO2 to DTR of the CM17A. Each goes through TWO inverter gates (in the SN7404 TTL chip) to convert the 3.3V signals to 5V.The code below subscribes to MQTT button push...
It's messy.... very messy.Here's the code:---------- more ----------/* Basic ESP8266 MQTT example This sketch demonstrates the capabilities of the pubsub library in combination with the ESP8266 board/library. It connects to an MQTT server then: - publishes...
On this occasion I have proposed to measure the electricity consumption of my entire house to make comparative estimates with the collection of my energy bill and analyze. On this occasion I will use the IoT platform Ubidots in its Industrial...
We are planning to use the NodMcu8266 to automatically log temperature and humidity measurements within the cloud, and show these measurements inside an online dashboard for this we use the DHT11 sensor...
In this IoT project, I have shown how to make IoT-based Smart Home Automation using Multiple NodeMCU ESP8266 network to control all the home appliances from the pushbuttons & Blynk App. If the internet is not available, then...
What Will You Learn During This Project Making how to use l298n motor driverwhat is mecanum wheelhow to use node MCUhow to upload code on node MCUhow to interface the bot with a smartphonewhat is sumo botand finally how to make wifi controlled sumo bot...
Hello guys, I made want to make a 7-segment display. But this time with bigger digits and RGB effects. Because this can be used to display some readings like Clock with Nodemcu, temperature monitoring using Arduino. Also, with an option of color changing...

In this IoT project, I have shown how to make an ESP01 Project using Blynk IFTTT to control a 2-channel relay module with the Google Assistant, and manual switch. During the article, I have shown all the steps to make this Blynk home automation...
Boian Mitov 3:01 PM Hello @Lindy Thank you for organizing this :-) In the meantime, you can all put your questions here > https://hackaday.io/event/158266-making-programming-easier and @Boian Mitov could give us an introduction? Stephen Tranovich 3:02...
So this article will go over the basics of the software, although all the real heavy stuff is done inside the various libraries.I could do with a little help here actually, as the WiFi code is a little bit unreliable, possibly to do with a relatively...
The Problems we are trying to solve.Before starting any electronic project a maker has to go through an Exhaustive //TODO listPrepare a list of right electronics componentsPrepare BOMSearch them locally or online to fit the BOMWait for the components...
This was a fun exercise to get started with my new ESP32 dev board from Amazon. The robot is cobbled together: Servos and Battery Packs are connected to the Breadboard using neon duct tape, and the R2D2 caster is held on with Velcro. It consists of...
INTRODUCTION I need quite a few solar panel sun trackers to generate as much power as possible from 60 solar panels. Why? well, we bought a farm in Spain, 120 acres of olive tree garnished paradise. I'm building a large, off-grid property...
In this IoT project, I have shown how to make an IoT-based Smart Home with Arduino IoT Cloud & Alexa using NodeMCU ESP8266 to control 4 home appliances with voice commands. If the internet is not available, then you...
