Parking in your home garage could be a bit of challenge if you have a bigger vehicle. You would like to make sure when you parked, you had enough space to walk around the vehicle. This Instructable describes an Arduino based garage parking assistant that would allow you to park in your best spot every time. It uses an ultrasonic transducer to measure the distance between your car’s bumper and the backside wall of the garage. A control box with visual indicators using bright Green and Red LEDs signals you when you are on the exact spot. Prior to its first use, you

Jesus Echavarria from Spain has tipped us off about his latest experimenting circuit board. This time he has made a testing circuit board for Adafruit’s FONA808 module that carries SIMCOM manufacturer’s SIM808 GSM and GPS transceivers. The Adafruit board includes this module and also some electronics for choosing voltage levels, battery connection and charger. Because I need to test and programming some of this modules, I decide to make an specific PCB for it, allowing the programming and debugging via PC, wich is more comfortable that use a microcontroller for all these tasks. I use the MCP2221 USB-Serial bridge and

Becky Stern’s new Instructables describes how to build a very simple realtime YouTube subscriber counter using a ESP8266 board and a seven segment LED display module. I was inspired by the Play Button awards YouTube sends out for subscriber milestones and whipped up a simple circuit using an ESP8266 wifi board and seven segment display to show off my realtime subscriber count. This is a great IoT beginner project, with just a little soldering and a code personalization required to make it work for your own account. Before attempting this project, you should be generally familiar with uploading new programs

With the rapid development and maturing of internet-of-things (IoT) technology, the IoT-driven smart sensors and systems are changing business in multiple industries. In healthcare industry, it is gaining more attention lately because of its immense potential in reducing the cost of tracking health information, as well as in providing health care to people who were not able to receive it before. This project describes a simple remote heart rate monitoring system based on the ESP8266 platform and the Easy Pulse Plugin sensor module. The ESP8266 reads in the analog photoplethysmograph (PPG) output from the Easy Pulse sensor, computes the heart beat rate in real time,
