How to send email and text messages using ESP8266

Posted on by 24 comments

Earlier we looked at a method of programming ESP8266 to send sensor data directly to Google Sheets without using any third party modules. Now, we will expand that a little bit and learn to send an email as well as a text message (SMS) using ESP8266. In this demo, we will configure our ESP8266 to send an email and a text message when the value of a variable (which could be a sensor output, or any other physical quantity) goes beyond a threshold limit. This is not entirely a new topic as there are similar tutorials available online to show how to do

Smart IoT alarm clock using Pi Zero

Posted on by Leave a comment

Here is a very comprehensive Instructable from fgebhart about building a smart IoT alarm clock using Pi Zero that has some really nice features such as text-to-speech synthesizer, multiple wake-up sounds (such as MP3 songs, your favorite internet radio station, or news channel), alphanumeric LED segment displays with auto intensity adjustment, and more. Features: text to speech synthesizer three ways of wake-up sound: play local mp3 files play internet radio station and play latest news as podcast (independent to the alarm time) set alarm via smartphone or any other computer running apache2 server automatic display brightness adjustment audio amplifier volume control 3D-printalbe case

Automatic pothole reporter

Posted on by Leave a comment

Potholes are one of the most common paving problems. They can not only damage vehicles but are also considered a serious road hazard. mchampio has posted an Instructables about building a NodeMCU based pothole reporter that records the locations of the potholes encountered during driving and later notifies the concerned authority. The location of the potholes are captured using a GPS module. Every time a pothole is encountered, the driver needs to press a push button to record its location. It can be further automated by installing an accelerometer for detecting the potholes.

Comfort thermometer with remote sensors housed in an Ikea Ribba frame

Posted on by Leave a comment

Building a thermometer is a very popular project among beginner hobbyists. This comfort thermometer display built with 517 LEDs and four microcontrollers is a beautiful piece of art work with a very impressive and colorful display. It uses: 1) PiC24FV16KA301 – controlling outer 36 RGB LEDs 2) PIC16F886 – bargraph and pink LEDs animations 3) ATmega328 – controlling 7-segment display 4) PIC16F57 – rf transmitter and receiver   The bargraph LEDs are current sinked with LM3914 LED display drivers, and current sourced via the PIC16F886 and transistors. The information from the temperature sensor (LM35) and humidity sensor (HIH-4030) is wirelessly transmitted once

Motion control camera robot for creating moving time-lapses

Posted on by Leave a comment

Motion-controlled autonomous camera robots are great for capturing moving time-lapse. Sacheth, Ope, and Jason (three ECE students at Cornell) built an iPhone controlled moving robot with a mounted camera to serve the same purpose. The position of the camera can be controlled as well through the iPhone App. Users can also pre-program it with certain motions with time intervals to capture a moving time-lapse of a landscape. The brain of their camera robot is the PIC32MX250F128B microcontroller that receives commands from the iPhone App over Bluetooth. Two DC motors are used to drive the camera robot, while a unipolar stepper motor controls the camera rotation. See the
