hi to all,

currently i'm a student as a computer technician.

and our teacher wants us to make a project that uses a relay, motor, sensor with the control of integrated circuit and i have no idea in making a project that uses that equiptment.

can u give me a project about it? if ever u have a suggestion .pls teach me

and how to operate on that project .

This is not an appropriate location (programming) for your posting. That being said, I have considered making a power attic fan controller, with summer and non-summer settings. In the summer, it would be controlled by a temperature sensor. In other seasons, it would be controlled by a simple circuit consisting of a couple of 555 timers, and a couple of AND gates, OR gates, and possibly a one-shot. The "winter" circuit would be powered by an old PC power supply, and the timer resistors wouldbe valued so that the fan would run for 30 minutes, every 6 hours or so. This would meet all requirements (motor, relay, sensor, chips) and would be way simple. Good luck.
