The purpose of the project is to build a simple charge controller for solar and wind systems based on IC NE555 Timer. Michael Davis, the designer, decides to use IC 555 instead of MCU because he worried that the microcontrollers would be too expensive or difficult to obtain in some parts of the world, and too difficult for non-technical people to program. The project works on 12 Volt systems but it can also be used for 24 Volt systems. The change that you need to do is replace the relay ...

The aim of the project is to build PIC32-based bathroom utilities management system. It will control and monitoring water and electricity usage to help user save money on utility bills. The system will turn off lights when not in use and limit water usage. The PIR sensor is used to detect when someone enters the room, the system will then turn on the lights, the door contacts and the pressure sensor will be used in conjunction with the PIR to determine if someone is still in the room, (possibly sitting ...

The Remote Video Control System will allow a remote user to fully control a separate video camcorder with a control board through InfraRed signal. The remote user has all the capabilities as if they were using the camcorder in-hand, including pan, tilt, zoom, Record, Display on/off, Tilt Position indicator, 4 speed settings, and even a real-time display through a TV sender and TV tuner/video display.The user's control interface consists of a development board with one joystick and six buttons to control the remote system. The joystick allows the camcorder system ...

The WatchDuck is an accelerometer-based low cost wireless pool alarm. It will give an alert when a child or an object fell into water. All operation in this project is controlled by PIC 18F23K20 microcontroller. The alarm is composed of two parts: the detector and the base station. The detector is using an accelerometer module (H48 from Parallax) and mounted into a bath ducky. The accelerometer measures the vertical acceleration (Z-axis) - the floating duck is following the surface waves of the pool.When an object – a child – fell ...
