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...

STM32F4 black pill EByte LoRa E32 E22 E220 shield v1.0
Mischianti Aug 31,2022
Detailed information on my siteFor LoRa E32, LoRa E22 and LoRa E220I start using STM32 microcontrollers, and I find they a superior quality. But I need some prototyping board to do my work faster.So here is a prototype board to develop the LoRa application. As usual, I use EByte modules, and this board is fully compatible with E32, E22, and E220.STM32F4 black-pill pinoutAs you can see in the pinout diagram you can find more than one Serial interface. In this board, I add jumpers to select Serial...

Luminator MAX3000 Driver Board
Goss Aug 31,2022
This is a custom driver to drive and control the MAX3000 line of electromechanical (also known as Flip Dot) display matrices. It allows individual control of each pixel on the display, chaining multiple board together, and a versatile number of options for power and component options. It features circuit protection on all I/O lines, and is both 3.3V and 5V tolerant.It is entirely implemented with jellybean digital logic circuits in order to keep costs down, and does not have any onboard controll...
