https://vimeo.com/394452423 Today I was finally able to get my raspberry pi configured as a wireless access point and DHCP router. Now The pi will serve out a network for the devices and run the broker for the mqtt protocol. This is a big deal because it means the light, controller, and pi (and any…
https://i.imgur.com/lbXWc7q.mp4 Remember Smartcar, the versatile and easy to use vehicle platform for your hobby-grade projects? It just received a powerful upgrade with an ESP32 as its “brain”, allowing it seamless connectivity via WiFi or Bluetooth. To sweeten the deal, it got new motors and fancy, custom-made chassis!

We introduced this concept last year, and have launched three games so far. Our final game of 2019 was SumoBots Battle Royale — where players from anywhere in the world can fight real robots in a battle royale-style arena. The aim of the project was to have the game run semi-autonomously, meaning that the…
The Arduino IoT Cloud platform aims to make it very simple for anyone to develop and manage IoT applications and its REST API plays a key role in this search for simplicity. The IoT Cloud API at its core consists of a set of endpoints exposed by a backend service, but this alone is not enough to provide…
In this project we will control a DC motor with a smartphone via bluetooth, learning more about: DC motors Interfacing Arduino with your smartphone Bluetooth L293D IC More info
Being a maker, I thought about this and decided that I will build a wearable device, a system which can help both patients with Alzheimer and their caretakers. This system should be able to carry out at least the following tasks: Reminding the patient of carrying out tasks, he/she has to do daily (such as…
NRA allows us, in case of bike accident, to locate the injured person through the Sigfox network. It also improves visibility on the road. For this build, I am using an Arduino MKR1200, a Neo 6-m GPS, a button, 2 leds, one 1k Ohm resistor, a buzzer, a vibration sensor and a 3.7v 150mah battery….
Connect your Arduino to the internet by adding ESP8266 WiFi Module! The ESP8266 Wifi module is a complete WiFi network where you can easily connect as a serving Wi- Fi adapter, wireless internet access interface to any microcontroller based design on its simple connectivity through Serial Communication or UART interface. Adding this module to your…
When you get a notification on your smartphone, more often than not, you’re doing something more pressing. You then silence the alarm, and perhaps forget about it. Nick Bild, however, has created a pair of smart glasses that take a new “look” at things by instead giving you a notification when you’re staring at an…
In this project we’re going to show you how to request sensor data via SMS with the Arduino. As an example we’re going to request the temperature and humidity from a DHT11 sensor. To send and receive SMS with the Arduino we’re going to use the SIM900 GSM shield. More info
Using an Arduino Nano 33 IoT, Jithin Sanal designed a home monitoring system capable of detecting noxious gases with an MQ2 sensor as well as sensing temperature, pressure, humidity, and ambient light via a BME280 sensor and an LDR. All of this is mounted onto a custom PCB that’s powered by a 9V battery, or…
