Cellphone chargers have been in existence for years and have grown from one stage to another. It started with the mobile phone traditional charger which had a USB interface, a DC converter, and a charging plug and now has expanded to a close-range inductive wireless charging. The commonly used inductive wireless charging is nice but limited, it still requires close contact with the charging pad making it of ...

Using the power of Arduino and utilising the camera and powerful performance of a smartphone QLRO has created a fantastic 3D scanner aptly named the AAScan. Check out the video below to learn more about the Android 3D scanner which is open source and fully automated. “I’ve designed my own 3D scanner! So, what’s different between this and many other designs on Thingiverse? First, it is minimalist. It only in ...

Mihir Shah has designed many a PCB in his time. However, when working through the development process, he grew tired of the messy, antiquated methods of communicating design data with his team. Annotating photos is slow and cumbersome, while sending board design files requires everyone to use the same software and be up to speed. Mihir thinks he has a much better solution by the name of InspectAR, it’s an a ...

Comma.ai is a self-driving car startup founded by George Hotz, the American hacker known for unlocking the iPhone and the PlayStation 3. Comma AI who originally wanted to build self-driving car kit, canceled their initial project due to safety concerns from NHTSA but later open-source their project and has now launched a Panda, an On-Board Diagnostics (OBD) II adapter that is expected to expose a car sensor ...

This instructable is the written version of my "Arduino : How To Control Stepper Motor via Bluetooth (with Smartphone)" In this project we will control a Stepper motor with a smartphone via bluetooth. My YouTube Channel First, you should see the following Instructable: How to Control a Stepper Motor With L293D Motor Driver Step 1: Tutorial https://youtu.be/EpLR4I9WYOU The Stepper motor used here is a rusty ...

Hello, everybody!!! It has been some time I had not updated my post here. Today I would like to share with you guys an experiment I made. I am going to control LEDs using MIT app inventor speech recognizer. Oh before I forget, I had also started a blog where I post some other Arduino Experiments. Feel free to visit to my blog at halim930112.blogspot.com Ok now, let's see what is needed to accomplish this ex ...

Now you can use your smartphone to check how clean the air is, measure the freshness of food or even the level of your blood sugar. This has never been so easy. All credit goes to the new spectrometer sensor which is developed at the Eindhoven University of Technology and can be easily attached to a mobile phone. The little sensor is just as precise as the normal tabletop models used in scientific labs. The ...

Smartphones in recent times have contributed to the growth of the medical sensing industries with a major success in the usage of a smartphone camera and flash to detect heart rate. Specialized Apps installed on the phone can use the phone inbuilt camera and flash to read an individual heart rate with high accuracy but nothing else in the space of health monitoring. Sensio is a biosensor that will allow sma ...

Most cameras these days offer some kind of built-in WiFI or Bluetooth control that allows you to fire your camera from an app on your smartphone. But not all of them do. The Ricoh GRII is one of those cameras that actually does offer some remote control via an app or USB remote, but sometimes you still want that tactile feel of pushing a shutter button, and the immediate response it gives. One GRII owner, S ...

Mood lamps are always fascinating for me and is a very good project for starters to start with Arduino. What is a Mood Lamp ? Mood lamps are lighting devices that are used to establish a particular feeling or mood within a room. In some cases, this type of lamp may be a small device that is plugged into an outlet and creates points of light near the floor line of the room. Other examples of a mood lamp may ...

https://youtu.be/Q05TAoPIHtQ I've been wanting to start exploring the world of microcontrollers and programming for some time now, so I came up with this simple project which uses an app called "Blynk" to allow you to wirelessly control an Arduino board through your wifi. Now obviously the end result isn't the most practical device you'll ever build, but this was a great way for me to learn the fundamentals ...
