Ultra TinyML: Machine Learning for 8-bit Microcontroller
leonardo.cavagnis Sep 05,2022
IntroductionIn this project, I will show an easy way to get started with TinyML: implementing a Machine Learning model on an Arduino board while creating something cool: a gesture recognition system based on an accelerometer.To make the experiment simpler, the system is designed to recognize only two gestures: a punch and a flex movement (in the data science field, a binary classification).The biggest challenge of this experiment is trying to run the prediction model on a very tiny device: an 8-...

TinyML: Slope control for Robots with Arduino Pro
leonardo.cavagnis Sep 05,2022
IntroductionThe vacuum cleaner robot is one of the most useful inventions of the last decade and anyone who says differently means that he does not have one! This fantastic household appliance is a concentration of technology: a complex embedded system composed of some microcontrollers, many sensors, and a lot of… software!But how many times do you get the feeling that your robot is stupid?In particular, in situations when your little helper blocks itself over an obstacle like a home carpet, a d...

How to Make Walkie Talkie Using Arduino
Adhikari Sep 04,2022
IntroWalkie-talkie using Arduino, humm.. sounds interesting isn't it?Alright, lets spend some time today and design and understand this fairly simple circuit, and lets find out how our expectations are challenged by the reality.StoryWhile compiling data for my tutorial on "nRF24L01 Module" (All About nRF24L01 Modules) I found this easy to use RF24-Audio library. This library has all the basic functionalities that you need to make a DIY walkie-talkie. The sketch is very simple, and I had all...

 From one of my previous projects (Bluetooth-controlled scrolling text), I have a finished 8x56 LEDs matrix consisting of 7pcs MAX7219 Led matrix modules 8x8, and located in the appropriate box. I used this ready-made matrix to make a scrolling weather station that displays the temperature, air humidity and relative atmospheric pressure, as well as the current time. For this purpose, I use a BME280 sensor and a DS3231 real-time clock module, so the device works independently of an Inte...

Arduino Laser Harp
Overclockers Sep 02,2022
An Arduino laser harp, using 7 small lasers and LDRs to switch the sounds. Buttons are used to change the instrument and pitch. The OLED screen displays the current setting (pitch and instrument), these can be changed in the code. Additional buttons and pots can be used for additional use cases. You can place a daughterboard on the nano to control more devices/midi etc.

Tic-Tac-Toe powered by D1 Mini
Rahn Sep 01,2022
IdeaThe Idea started when I was working on a birthday present for a friend. It was a 7 Segment Clock powered by an ESP32. The core part was to build something powered by a microcontroller by using a PCB and a Bettery Pack. I then setteled on building a Tic-Tac-Toe because I thought it was relatively simple. The code would be simple, the PCB-layout would be simple and it would be easy to manufacture a couple of them.JourneyAfter setteling on the idea I started working on the form. It shouldn't be...
