LEDs are ideal indicators, and our diffused LEDs are fairly bright and we use them in our projects all the time. They go easily into a breadboard and will add that extra zing to your project. Pack of 10 diffused red LEDs 3mm diameter 1.85-2.5V Forward Voltage, at 20mA current 100+ mcd typical brightness Specifications Resources Datasheet Sample Code  Tutorial

In the world of electronics projects, we need headers, headers and more headers. Each pack contains ten 40-pin break-away male headers, 0.1" (2.54mm) pitch.  Breakaway headers are like the cello-tape of electronics. They're great for connecting things together, soldering to perf-boards, sockets for wires or break-away header, etc. We go through these guys real fast, and thought that given how handy they are, we'd offer them in a pack of ten! These headers are even tin plated so they wont oxidize! You can cut these down to different sizes fairly easily, simply break apart, or use diagonal cutters to cut in between pins.

These switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard as well. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed.They come in a pack of 20, they're pretty handy so you'll want to keep them around.You can find an EAGLE cad package for these in switch-omron:B3F-10XX Product Dimensions: 6.0mm x 6.0mm x 5.0mm / 0.2" x 0.2" x 0.2" Specifications Resources Datasheet Sample Code  Tutorial

LEDs make great indicator lights. They use very little electricity and they pretty much last forever. You cannot directly connect an LED to a battery or voltage source. Firstly, because the LED has a positive and a negative lead and will not light if they are the wrong way around and secondly, an LED must be used with a resistor to limit or 'choke' the amount of current flowing through the LED - otherwise the LED could burn out! LEDs are ideal indicators, and our diffused LEDs are fairly bright and we use them in our projects all the time. They go easily into a breadboard and will add that extra zing to your project.

The dimensions of the card: 50mm * 37mm Final dimensions: 50 mm * 37 mm * 17 mm (length * width * height in maximum position, contains height of the copper foot)   Instruction: The first test must be fully charged. Connect the battery to be tested positive for positive input, a negative input for the negative, can not be reversed (with reversal load can damage the circuit)! Load connected to the output of the positive and negative output, to work with the micro USB power tester (not available desktop or laptop powered USB), then the battery voltage. Direct boot test need only one press of the "OK" button, the tester can develop a proper battery charging voltage complete charging voltage, and starts flashing after the test three times. They need to develop artificial display status of the termination voltage only when the battery voltage by pressing the "+" or "" - "button to change the termination voltage display start with P, behind the representative voltage resolution of 0.1V , set up after pressing the "OK" start test button. After the start of the test the tester will check the load of the electronic switch is turned on, the test data shows that the process will release capacity (Ah), current discharge current (A) and the battery voltage (V) between the wheel was. When the battery voltage reaches the cut-off voltage set, load control turns off the display data tester remains in capacity (Ah) and above and the corresponding indicator flashes quickly together, now displays the battery capacity is capacity discharge, about the press the "OK" button to finish flashing allows stable data display, Press the "OK" button again to return to the power state can simply replace the battery test the next section.   Error codes: Err1: battery voltage is above 15 V Err2: battery voltage is lower than the termination voltage Err3: Battery cannot afford load or discharge line current too much resistance Err4: overcurrent (current exceeds 3.1A) Specifications Power supply voltage (VDC) 4.5 ~ 6 Discharge voltage 1 ~ 15 VDC 0.01V resolution Working current (mA) less than 70 Maximum voltage measurement error 1% + 0.02V Maximum current measurement error 1.5% ± 0.008A Length (mm) 50 Width (mm) 37 Height (mm) 16.5 Weight (gm) 20 Shipment Weight 0.030 kg Shipment Dimensions 12 × 8 × 2 cm Tutorial

These are our favorite trim pots, perfect for breadboarding and prototyping. They have a long grippy adjustment knob and with 0.1" spacing, they plug into breadboards or perfboards with ease. This is the same pot that comes with our character LCDs and tutorial packs.

Piezo buzzers are used for making beeps, tones and alerts. This one is petite but loud! Drive it with 3-5V peak-to-peak square wave. To use, connect one pin to ground (either one) and the other pin to a square wave out from a timer or microcontroller. For the loudest tones, stay around 4 KHz, but works quite well from 2KHz to 10KHz. For extra loudness, you can connect both pins to a microcontroller and swap which pin is high or low ('differential drive') for double the volume.
