Level shifting chips let you connect 3V and 5V devices together safely. This chip is similar to others in the shop (such as the 74LVC125) except this one is particularly good at converting 3V logic up to 5V. This is in demand especially when connecting some 3V devices such as the Teensy 3 to NeoPixels! Just power the 74AHCT125 with 5V, it will detect 3V logic properly. You can also use it to connect 5V logic out to 3V logic in, that's when you want to power the 74AHCT125 with 3V, it can safely read 5V logic on the input pins.
To use, apply 3-5V power to the VCC pin, common ground to the ground pin, and tie the /OE (output enable) pins to ground. Data goes in on the A pins and goes out on the matching Y pins. Check the datasheet for the pinouts!
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...
This \'full-size\' breadboard with 830 tie points is perfect for small and medium projects. it\'s 2.2" x 7" (5.4cm x 16.5cm) with a standard double-strip (630pts) in the middle and two power rails (200pts) on both sides. You can pull the power rails off easily to make the breadboard as thin as 1.4" (3.5cm). You can also "snap" these breadboards...
Electrolytic decoupling capacitors 1000uF/6,3V. 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.
This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive female barrel jack. If you have a power supply with a barrel jack and want to plug it into a breadboard, this might be the simple solution.
This is a very common 10nF capacitor. Used on all sorts of applications to decouple ICs from power supplies. 0.1" spaced leads make this a perfect candidate for breadboarding and perf boarding. Rated at 50V.
The MQ5 is used in gas leakage detecting equipment in consumer and industry applications,this sensor is suitable for detecting LPG, natural gas, coal gas. Avoid the noise of alcohol, cooking fumes and cigarette smoke. The sensitivity can be adjusted by the potentiometer.
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.
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 sealed Digital Temperature Sensor DS18B20 1 meter probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.
