In this tutorial we are going to learn some basics on using Keypad 4x4 on Arduino. by mybotic @ instructables.com This keypad consists of 4 rows x 4 columns of buttons. It is ultra-thin that it provides an useful human interface component for microcontroller projects. Convenient...

by Guillermo Jaquenod @ edn.com Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” method as an effective way to drive M=N×(N–1) LEDs using...

Tahmid built a TV tuner IR remote with a PIC16F684: I then proceeded to write an IR transmitter using the PIC16F684 (using the MPLAB X IDE and XC8 compiler), following the timing information from the extended NEC protocol. In order to connect all the keys, I connected them in...

by Clemens Valens @ elektormagazine.com: The new PIC32MM family, currently Microchip’s lowest power 32-bit PIC32 family, features sleep modes down to as little as 500 nA. Filling the gap between the PIC24F XLP and PIC32MX families, the new family also offers so-called core...

A JavaScript microcontroller you can program wirelessly - perfect for IoT devices! No software needed so get started in seconds With our custom circuit board, the latest Nordic chip, Bluetooth Smart, Infra-red and much more, all enclosed in a tiny silicone case, Puck.js is a smart...

Rahul Sreedharan introduces us to TI's MSP430 microcontroller using LaunchPad board. In this tutorial we will be exploring the workings of a MSP430 based microcontroller from Texas Instruments. MSP430 is developed by Texas Instruments as an extremely low power 16 bit architecture for...

Shawon Shahryiar @ embedded-lab.com introduces us to Tiva C series microcontrollers from TI. The Tiva C series MCUs are high performance ARM Cortex M4F micros. Now what does that mean? Generally speaking the ARM Cortex M series is meant to be used in place of (or simply replace)...

A Basic board to test the Atmel SAMD09. On board there is also a CH340 uart to usb bridge Build this board to getting started with the SAMD microcontroller family after I made the mistake to try the much bigger SAMD21 first. The SAMD09 used here is he smallest from this family and...
