Create 16x16 LED Displays with Flexible Reference Design

Hobbyists and makers now have more flexibility and options when developing LED signs, using the MAXREFDES99# 16×16 display reference design from Maxim Integrated Products. LEDs continue to dramatically transform signage and lighting. However, often LED displays today are 8×8 and cannot communicate many international alpha-numeric characters. MAXREFDES99# integrates four MAX7219 LED drivers to provide designers a 16×16 display with 256 LEDs, allowing them to create signs in multiple languages...

Expansion Shield RaspberryPi compatible Arduino. Part
Expansion Shield for RaspberryPi compatible with Arduino. Part 2 - Use the Shield on RaspberryPi

To proceed in subsequent operations, use RaspberryPi in terminal mode, the two SSH and SCP windows open and root login. Connect the RPY connector of the shield to the GPIO RaspberryPi connector and give voltage. Now we shall activate the I2C and SPI management modules (drivers in the Windows world) or just one of the two, depending on your needs...

Expansion Shield RaspberryPi compatible Arduino. Part
Expansion Shield for RaspberryPi compatible with Arduino. Part 1 - Schematic

Let’s expand RaspberryPi functionalities with a shield that is compatible with the Arduino pinout and with an onboard analog to digital converter with 16-bit resolution. Further expansions that we will present in the future will allow you to add a DAC, a number of additional digital I/Os and the ability to connect also with non GPIO enabled boards...

AVR takes under micro process quadrature
AVR takes under 1µs to process quadrature encoder

Reading quadrature encoder signals at high speeds often requires dedicated hardware. This Design Idea shows a simple scheme to accomplish this function using only an ATtiny2313A AVR microcontroller...

Arduino Primo base board features native
Arduino Primo base board features native Bluetooth low energy wireless connectivity and NFC Touch-to-Pair using Nordic Semiconductor nRF52832 SoCs

Nordic Semiconductor announces that Arduino – the world’s most successful open-source ecosystem for education, Maker, and Internet of Things markets – has specified the Nordic Semiconductor nRF52832 Bluetooth low energy System-on-Chip at the heart of its latest product: a low cost IoT-targeted programmable single board computer (or ‘base board’) called the ‘Arduino Primo’...

Review Single board 65C02 65C816 computers
Review: Single board 65C02 and 65C816 computers

The 6502 is a classic piece of computing history. Versions of this CPU were found in everything from the Apple II, to the Nintendo Entertainment System, and the Commodore 64. The history of the 6502 doesn’t end with video games; for the last forty years, this CPU has found its way into industrial equipment, medical devices, and everything else that doesn’t need to be redesigned every two years...

Review Microchip Curiosity is gorgeous new
Review: Microchip Curiosity is a gorgeous new 8-bit dev board

Microchip has unveiled a new dev board called the Curiosity Development Board. I had my first look at this at Bay Area Maker Faire back in May but was asked not to publicize the hardware since it wasn’t officially released yet. Yesterday I got my hands on one of the first “pilot program” demo units and spent some time working with it...

TI introduces world first microcontroller configurable
TI introduces the world's first microcontroller with a configurable low-leakage transimpedance amplifier

Texas Instruments customers can now extend battery life in sensing and measurement applications with the new MSP430FR2311 microcontroller, the industry’s only MCU with an integrated low-leakage transimpedance amplifier consuming just 50 pA of current...

The perfect Remote, Programmable, Controller for interactive LED strips. Part 2 - Controller Configuration, Connections and Operation

The receiver provides for the control of the two channels by a 433 MHz remote control with MM53200/Holtek HT12 encoding or a compatible one. Each channel is controlled by two buttons (also of distinct transmitters), hence  to manage both channels four buttons are needed, i.e. a four-channel radio control transmitter or two  two-channel transmitters, one used to control the brightness of the warm light and one for the control of cold one...
