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.
This is the transistor used in our Sparkfun Invento rsquo;s Kits.
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...
If you\'ve ever wondered how to control high current devices from a low-power microcontroller, a MOSFET is what you need. The NDP6020P is a very common MOSFET with very low on-resistance and a control voltage (aka gate voltage) that is compatible with most 5V and 3.3v microcontroller or mechanical switches. This allows you to control high-power devices...
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.
This is the basic L7805 voltage regulator, a three-terminal positive regulator with a 5V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.5A.
