Overview This project has come about from my desire to control my home heating from work. As I have a VPN between work and home a straightforward relay controlled from a PC would seem the easiest solution. However I also wanted a control unit that I could operate in the house without resorting to the […]
This page describes a PIC10F200-based electronic dice. The reason I made this was that I got a small corner left over when ordering a panel with a couple of other PCBs and thought I would rather use the corner for something fun than leave it unused, so I made a dice. The PCB is quite

Temperature and relative humidity are two very important ambient parameters that are directly related to human comfort. Monitoring these factors becomes even more crucial in various applications such as environmental control systems and indoor climate management. Integrating sensors like the Sensirion SHT1x/SHT7x can provide precise measurements, ensuring optimal conditions for occupants while also enabling efficient
The device used for measuring daily insolation has been developed. The device was built with a PIC18F458 and the 128MB Multimedia Memory Card, MMC. The solar radiation is measured by a calculator solar cell. The PIC chip interfaces the MMC using SPI mode. The interval between samples is set to one minute. The firmware detects
Introduction After I made the clock, the pong and tetris games I thought that it also would be cool to connect the game system to a standard rs232 port and scroll text comming from the port. When I thought about it, I found that there is a problem scrolling text comming from a RS232 port

How to choose a MicroController It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips. But times have changed. Digikey

âReady for PICâ is one of MikroElektronikaâs compact prototyping boards for 28 and 40 pin PIC microcontrollers. The board comes with PIC16F887 microcontroller which is preprogrammed with an UART bootloader firmware and thus eliminates the need of an external programmer. The on-board USB-UART module allows the serial data transfer between the PIC and a PC
This post provides the LCD[1] interfacing code using only 3 pins of PIC16F84A microcontroller. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom of this page. It is assumed that you know how to make an LED blink with PIC16F84A microcontroller. If you

Introduction Tetris is a very simple, but elegant game. Blocks of four bricks each are falling down in a play field, and the player can rotate and move the block sideways. When the block hits ground or another block below, it stays there. If one line of bricks is full, then that line is removed.
Introduction The game Pong was the world’s first video game in the early 70’s, it is a tennis lookalike game where a ball is played with two rackets, which are moved up and down by each player. The ball can bounce at the floor and the ceiling. This version is implemented with the virtual game
