Amperímetro de 3 dígitos con PIC16F684

admin — Tue, 29 Mar 2011 14:59:02 +0000

Here is a digital Amp meter based on PIC16F684 and ACS712 current sensor. The measured DC or AC current will display on 3 digits 7-segment with resolution 100 mA. The current sensor in this project is ACS712ELCTR-30A-T from Allegro(I got from ebay). It can measure the AC or DC current up to 30A with 66 mV/A output sensitivity. This project identical to my volt meter project except the microcontroller not same.

Cómo funciona un teclado matricial

admin — Tue, 01 Mar 2011 16:28:49 +0000

What you probably have in front of you, is a keyboard with more than 100 keys on it... If you are not familiar with the key matrices, then you may think that inside this keyboard, there is a chip (probably a microcontroller) that has at least the same number of inputs to read each key separately. Well, this is far from true...

Caracteres personalizados en LCD usando PIC

admin — Tue, 01 Mar 2011 16:19:37 +0000

The 16x2 LCD is very popular because of it's built in HD44780 interface module. This module makes it extremely easy to add an LCD to any project with its built in character set and easy command structure.

Controlar un LCD con solo 3 cables usando PIC12F683

admin — Tue, 05 Oct 2010 13:45:51 +0000

HD44780 based character LCDs require at least 6 I/O lines from microcontroller to display data. Therefore, they are not suitable for low-pin microcontrollers like PIC12F series microchips. In this project, I am going to show how to drive an HD44780 based LCD display with only 3 pins of a microcontroller. I am going to demonstrate it with PIC12F683 microchip. The character data and command from the microcontroller is transferred serially to a shift register (74HC595), and the parallel output from the shift register is fed to LCD pins.

Superprobe basado en PIC16F870

admin — Tue, 05 Oct 2010 13:24:30 +0000

As the name suggests, at its simplest the Superprobe can be used as a logic probe, displaying an L, H or - if it touches a point in the circuit that is in a low, high or floating state. What makes it so "super" is that by using the two input buttons you can switch it to a different mode. The supplied software provides seventeen different modes, including a logic pulser, frequency counter, voltmeter, capacitance meter, signal generator and serial ASCII data output.

Controlar un LCD con Arduino

admin — Fri, 23 Jul 2010 18:58:35 +0000

This is a bit of a side note, there's no LCD included with the Arduino starter pack, but I figure its a popular request, so here we go!

The LCDs run on +5v and require only 6 data pins to talk to. You can use any data pins you want!

This tutorial will cover character LCDs

Tetris en un microcontrolador – Pic18LF4520

admin — Mon, 28 Jun 2010 15:13:13 +0000

The PIC Tetris game (PICtris) spawned from a recent question by RetroBrad in the forum. He wanted to know how to manipulate LEDs and draw 2D graphics. I'm more of a practical kind of guy and in the past, graphics were never an area of concern. I was intrigued to delve into the world of 2D to find out how things tick.

Amicus 18: Desarrollo con PIC al estilo Arduino

admin — Mon, 28 Jun 2010 14:39:21 +0000

What is Amicus?

Amicus is a multifunction development system inspired by the popular Arduino board, however, the Amicus board uses a Microchip PIC® microcontroller instead of an Atmel AVR® type.
