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.
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.
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...
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.
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.
This 47 x 35mm (1.84 x 1.37") breadboard has 17 rows of tie points, enough for up to two 14 or 16 pin DIP integrated circuits (ICs). The board features an adhesive backing and is Transparent color. Add some color to your next project!
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 yellow lens. It has a typical forward voltage of 2.0V and a rated forward current of 20mA.
This is the P2N2222A, an NPN silicon BJT (Bipolar Junction Transistor). This little transistor can help in your project by being used to help drive large loads or amplifying or switching applications. The P2N2222A is specifically rated at 40V and 200mA max
