An adjustable potentiometer can open up many interesting user interfaces.
Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the
other, and the center pin will have a voltage that varies from 0 to VCC
depending on the rotation of the pot. Hook the center pin to an ADC on a
microcontroller and get a variable input from the user!
This pot has a 1/4" mounting diameter and has a 10K linear taper. Check the
datasheet for dimensional drawings.
This is a cute half size breadboard which has 400 tie-points, is great for small projects. it\'s 2.2" x 3.4" (5.5cm x 8.2cm) with a standard double-strip (300pts) in the middle and two power rails (100pts) on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm) and stick it onto your Raspberry Pi. You...
Miniature Single Pull Single Throw switches. These are high quality Omron type B3F momentary on switches. This switch has a very large 5mm tall button. Perfect as an embedded switch behind an enclosure wall. Rated up to 50mA.
it\'s a "soft touch" T18 RED knob that works great with our Panel Mount 10K and Panel Mount 100K potentiometers. The knob is designed to set directly on the potentiometer\'s ridges so it\'s an easy amp; secure fit. It has a nice feel, with a rubbery grip, tweaking it is quite fulfilling.
LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays.This is a very basic 5mm LED with a green lens. It has a typical forward voltage of 2.0V and a rated forward current of 20mA.
The Rotary Potentiometer - 100k Ohm is an adjustable potentiometer can open up many interesting user interfaces.Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to theother, and the center pin will have a voltage that varies from 0 to VCCdepending on the rotation of the pot. Hook the center pin to an ADC on a...
The LM335Z is a very easy-to-use analog temperature sensor. The LM335Z works like a Zener diode with a breakdown voltage proportional to absolute temperature at 10mV/¡K. Hook up a resistor from 5V and GND, and the LM335Z will output an analog voltage of 2.98V (298 Kelvin is 25C or room temperature). The output of the sensor is linear, and when...
If you are sourcing a ultrasonic ranging module , the HC-SR04 is good choose . Its stable performance and high ranging accuracy make it a popular module in electronic market .Compared to the Shap IR ranging module , HC-SR04 is more inexpensive than it . But it has the same ranging accuracy and longer ranging distance.
The Potentiometer brick produces analog output between 0 and Vcc (5V DC witd Seeeduino) on its D1 connector. The D2 connector is not used. The angular range is 300 degrees witd a linear change in value. tde resistance value is 10k ohms, perfect for Arduino use. tdis may also be known as a rotary angle sensor.
Electrolytic decoupling capacitors 100uF/25V. These capacitors are great transient/surge suppressors. Attach one between the power and ground of your project to ensure smooth power delivery. High quality radial electrolytic capacitors.
