Can you turn the regulator on and off?
My question is, would it work to turn the regulator on and off using the arduino to provide the intermittent power to the load or would it be better to leave the regulator on and use a separate transistor to turn the load on and off using the arduino.
How does a slide switch in a circuit work?
The slide switch is a device to connect or disconnect the circuit by sliding its handle. They are quite common in our surroundings. Now let’s see how it works. Just as its name suggests, slide switch is to connect or disconnect the circuit by sliding its switch handle so as to switch the circuit.
How to use slide switch on Arduino Uno?
See the circuit symbol for slide switch and 2 is the middle pi. Here we use a slide switch to control the on/off of an LED which is simple. Connect the middle pin of the switch to VCC. Connect one pin at one end to pin 12. After connecting a 10K resistor and a 104 capacitor, connect it to GND (to let the switch output stable level signal).
What kind of slide switch can I use?
The common types of slide switch include single pole double throw, single pole triple throw, double pole double throw, and double pole triple throw and so on. Generally, it is used in circuits with a low voltage and features flexibility and stabilization.
How does a transistor control a DC motor?
Breadboard drawing of a transistor controlling a DC motor with a potentiometer. When you turn the potentiometer, you’re producing a varying voltage on the wiper pin. That means you’re changing the voltage on the base of the transistor.
How are transistors used to control high current loads?
You can use transistors from circuits like these. For example, you might put a transistor on the output pin of a 555 timer IC (which produces a variable timing pulse), or a shift register IC (which allows you to produce multiple control signals in parallel) to control high current loads from those devices.
How is the base voltage of a transistor controlled?
The voltage on the base of the transistor doesn’t have to be controlled by a switch. You can use a potentiometer, connected as a voltage divider, to produce a changing control voltage for the transistor’s base.
