Hi There,
I'm working on a project with my son and I, unfortunately, have very little knowledge of electronic assembly. I have a very good knowledge of computers, networking and can recognize electronic components fairly well (capacitors, resistors, transistors, ICs + values and other simple stuff). I can solder too, but I don't know how to build circuits. Please help us.
Overall Objective:
We'd like an infrared sensor or two that crisscross each other to detect when a radio controlled car enters a square perimeter of about 5x5 feet. Once the car is detected to have entered this space (anywhere within it) the gate starts its travel upward to open then stops.
The module should perform the following:
The circuit should pick up a motion within this 5x5 foot entry area using an infrared mesh spread across the area floor with no reflectors or any other items on the floor of the perimeter that could cause the car to stumble or catch. I'm open to other technologies other than infrared depending on your recommendations.
Once motion is detected a timer should be triggered to start counting for about 20 - 30 seconds (adjustable). When the motion is detected, and the counter is started, the circuit should send out a signal to ease ON a HVAC motor that lifts the gate. When the timer stops counting it should send out a new signal to ease out or turn OFF the HVAC motor so the gate stops lifting up. The gate can then stay up. Now, if his friend's car enters the 5x5 area the timer should reset and start the count from the beginning again until it reaches 20 - 30 seconds (adjustable), resulting in the gate stopping higher up than if only his car would have entered alone.
I hope that makes sense. Thank you so much for your help.
