Using switches with an Arduino - Input Pull-Up / Pull-Dow

Each Arduino pin is powerful enough to control a single LED (20mA of current), but as currents get larger a switching device is needed A MOSFET can be used for amplifying or switching signals - in this example, we'll be using it as a switch. It consists of 3 terminals: gate, source, and drain (pinout is below). The N-channel MOSFET is a voltage-controlled device. There are two types of N-channel MOSFETs: enhancement- and depletion-type. An enhancement type MOSFET is normally off when the gate-source voltage is 0V, so a voltage must be applied to the gate for current to flow through the drain-source channel. A depletion. switch (var) { case 1: //do something when var equals 1 break; case 2: //do something when var equals 2 break; default: // if nothing else matches, do the default // default is optional break;

Like I said - pretty basic. So just what is happening in this circuit - and why would this circuit work anyhow? According to the Arduino web page In addition, some pins have specialized functions. How to use MOSFET as a switch? To use a MOSFET as a switch, you have to have its gate voltage (Vgs) higher than the source. If you connect the gate to the source (Vgs=0) it is turned off. For example we have a IRFZ44N which is a standard MOSFET and only turns on when Vgs=10V - 20V. But usually we try not to push it too hard so 10V-15V is common for Vgs for this type of MOSFET. However. The collector is one side of the switch in a transistor, this is connected to the emitter (other side of the switch) when the base pin is has a voltage applied. An easy way to remember what goes where on a transistor is: The Collector collects whatever the Emitter will emit when the Base commands it to So in this case we are going to collect the negative from the.

How to Connect a Push Button Switch to Arduino Hand

When hooking up switches or buttons to an Arduino I/O pin, sometimes the results might appear completely random. Sometimes it will appear as though there is a delay from when the button is pressed until the state of the pin actually changes. Other times the pin's value will seem to randomly fluctuate from HIGH to LOW. Even more maddening might be as your finger gets closer to the switch, the pin's state changes! The fix to these problems is simple: use the Arduino Internal Pull-up. You can connect all the switches in parallel if you only need to know when one of the switches closes. If you need to know which one, you will need to connect each switch to a separate pin. You can use a pull-up resistor or a pull down resistor. Either way, the input will not be floating when the switch is open. Regards, Keit
