Our finished design for our machine
The finshed program for our project.
The first thing we decided to do was to run some tests on different parts of the robotics kits, starting with the switch. The switch is a standard switch with two outputs, a NO output and a NC output. The three is normally unchecked and when tested it resulted in a zero, with no voltage output. When using the two, its normally checked and when tested it gives a 1 in the testing window and it has a voltage. This means that switching between two and three switches the results of the test. Next we tested the potenteometer, which had values between 43 and 5000, and the NTC resistor had a value of 5000 and 1183 after it got heated up. With the outputs if you changed the output voltage the volume or speed of the product was also changed .
You can also change the CW to CCW on the motor by switching it's polarity. The reed switch is controlled by magnets so if you add an electromagnet the switch will be triggered, which switches it from a value of 0 to 1. The reed switch is also a closed program. The photoresistor and phototransistor are light sensitive sensors. When there is light, the photoresistor is closed, but when there is no light it is open. the phototransistor has less resistance when there it no light and more resistance when there is more light. The mini switch is open when there is a break in the circuit and is closed when there is a complete circuit.
You guys built a neat solution for this problem.
ReplyDeleteTake a look at the assignment and make sure you address all the issues! Thanks.
