Interfacing a Keypad to a PIC Microcontroller – Flowcode

A keypad is a combination of push-buttons in a way to form rows and columns, in this way the number of input/output pins necessary for their connection is reduced. A 4x3 keypad requires 7 input/output pins while a 4x4 will require 8. Flowcode simplifies all the routines, the Keypad macro contains all the necessary functions for reading thes keypad as well as for initializing the port it is connected to.

Interfacing Matrix Keypad with PIC Microcontroller – MikroC

Keypads are small keyboards that are used to enter numeric, alphanumeric or select configuration data to microcontroller systems. Keypads are available in a variety of sizes. The common sizes are 3x3, 4x3 and 4x4 keypads. A matrix keypad is basically a combination of push-buttons in a way to form rows and columns. In this way the number of input/output pins necessary for their connection to a microcontroller is reduced. A 4x3 keypad requires 7 input/output pins instead of 12 and...

Automatic Temperature Control System using PIC Microcontroller – MikroC

An automatic temperature control system has the ability to monitor and control the temperature of a specified space without human intervention. This project uses a PIC microcontroller to automatically control the temperature of an area. This area could be a small plant, a house or any place or device that require a controlled temperature like an incubator (egg) for example. The desired temperature setting is entered using a keypad. The temperature of the area is measured using an analog...

Arduino Shield Tutorial – Make Your Own LCD Keypad Shield

Arduino shields are boards that can be plugged on top of the Arduino PCB to extend its capabilities. This makes prototyping with Arduino plug and play. Instead of soldering or wiring external devices or sensors, you can simply hook your board with a shield. This is another practical tutorial, we're gonna build a fully working complete Arduino LCD Keypad shield, we're gonna go through all the steps, we'll start from scratch explaining and simulating the circuit diagram in Proteus,...
