I am road testing https://www.element14.com/community/roadTests/2184/l/Arduino-MKR-WAN-1300-+-ENV-Sensor-Shield ,  and this is simple point to point communication test using two Arduino MKR 1300.  As part of the test I am using an Arduino MKR Environment shield on one of the MKR 1300  boards and other board is connected to an OLED display to show the Temperature, Humidity , Illuminance, and UVIndex. In addition as you see in the picture below, I am also keeping track of the packet ...
This is a continuation of the blog post I posted earlier this week Arduino MKR WiFi 1010 + MKR ENV Shield , as part of this blog post I using am using Arduino MKR 1010 (a MRK family of boards that has WiFi and Bluetooth), MKR Environment Shield to post sensor values to Arduino IoT cloud, and an I2C OLED to display sensor values and to show data posted on the Arduino IoT cloud.   I have always wanted to try Arduino IoT cloud and finally thought that I should give it a try , ...
I am road testing https://www.element14.com/community/roadTests/2184/l/Arduino-MKR-WAN-1300-+-ENV-Sensor-Shield , as part of this blog post I am going over the MKR Environmental Sensor Shield. For this I am using Arduino MKR 1010 which I had in my parts bin (a MRK family of boards that has WiFi and Bluetooth).     The MKR ENV Shield allows a MKR board to acquire environmental data collected by an array of sensors. These sensors are of the latest generation and measure atmospheric pre ...
This is a countdown clock made with the Adafruit Pro Trinket 5V 16MHz, Adafruit DS3231 Precision RTC Breakout, and 2x Adafruit 0.56" 4-Digit 7-Segment Display w/I2C Backpack - Blue. Schematic created by Adafruit   The clock is set to countdown to November 2, 2020 at 12AM. This is the beginning of a three day period in which there is a 1 in 240 chance that Near Earth Object 2018 VP1 could potentially impact the Earth. https//cneos.jpl.nasa.gov/sentry/details.html#?des=2018%20VP1  ...

So, I wanted to try out the Arduino IoT Cloud. I present to you this little project of a data logger and will also show you the steps to follow along to get started with Arduino IoT Cloud.   First of all Arduino is having free upgrade for 3 months to their maker plan/ With that plan you can create lot many things and connect lot many boards at same time. If you want upgrade now, Tweet - https://twitter.com/Hacksterio/status/1241057617524514818   In this simple getting started post, ...

Haptics

Posted by dikshita Mar 19, 2020
Prosthetics are becoming more common in the market today. I recently saw a kid wearing a thanos hand and thought I'd put my old heptics project here. We create a skeleton (metal cut, CAD) and use it mimic a human hand. A simple project but good advance level application of pots I believe.   Overview The project is on creating an artificial arm prototype that mimics the human hand. We use pots at all the joints and as my hand moves the value of the Pot changes resulting in resistance vari ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   The CAPS LOCK key is the most annoying key on the keyboard. Majority of the times, you have noticed, It’s always getting in the way. Ever enter a password with CAPS LOCK enabled? Huh...   Enough times to get locked out of your account?  Yeah, me ...
Hello,   After doing some research I haven’t found exactly what i’m looking for. Basically I looking for a way to translate movement of an object in a video file (like a recording of a ball jumping up a down) to values that I can use to move servos. I’m more comfortable with arduino so that’s the microcontroller that I’m aiming to use with this project. I’d like to either be able to move the servos in realtime in sync while playing the video or saving t ...
At CES 2020 Arduino is promoting its industrial grade Arduino Pro IoT solution with the Arduino Pro IDE, Arm Pelion IoT Platform for device management, and a new line of Portenta industry-grade boards, beginning with the Portenta H7 board powered by STMicro STM32H7 dual-core Arm Cortex-M7/M4 Microcontroller.   My Gallery Title     The first member of a new family of industrial grade boards, the Arduino Portenta H7 module sports a dual-core Arm Cortex®-M7 and Cortex ...
I would like to have accurate motor control in the robot I am planning.  Accordingly, I have been experimenting with encoders attached to the motors that provide feedback to a Proportional Integral controller.  This post is a demonstration of the progress and what looks to be a promising start.   Introduction   The final robot will probably have a Raspberry Pi as the "brain" since I would also like to have facial recognition.  To unload the Pi, microcontrollers will be ...
Updated 2 Jan 2020:  Embedded 2nd video   I am starting to plan ahead for a robot that will have image recognition using a Raspberry Pi.  Image recognition being computationally intensive, the plan is to offload the Pi with microcontrollers connected with I2C.  In previous post an I2C template for connecting a Raspberry Pi with Python to a microcontroller with the Arduino IDE is described.  This post is the first of two parts describing how a microcontroller can be used ...
In a previous post the sending of a single byte using I2C between a Raspberry Pi (master) running a Python 3.7 script and a microcontroller using Arduino libraries was described.  In this post a more useful template with multiple byte transfer is presented that demonstrates control of GPIO, ADC, PWM, and stored data.   Introduction   I have been thinking about building a robot that has Image Recognition using a Raspberry Pi but that is a full time task for a Raspberry Pi.  ...
This post demonstrates simple sending and receiving of data from a Raspberry Pi using Python 3.7 to a microcontroller using the Arduino libraries.  There is a follow-up post here that demonstrates multi-byte transfer and control of GPIO, ADC, PWM, and stored data on the microcontroller.   Introduction   I have been thinking about building a robot again and would like to be able to use Artificial Intelligence / Image Recognition.  The two leading candidates for the main proc ...
  WARNING: This blog involves high voltages around sensitive low-voltage devices. Take great care if you decide to try this for yourself.   Recently, I received a swag pack that included an UNO and a Blue Man so I thought I'd do a very short and simple experimenting-type blog that could, maybe, lead on to something seasonal.   Here they are, the BM and UNO, along with some of the components I'm going to use: a 2k7 resistor; an MPS42A transistor; a 10mH inductor; and a neon bulb ...
