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.

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.

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 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

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.

This is JoyStick Module PS2 Breakout Sensor very similar to the ‘analog’ joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply two potentiometers – one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is press down. With the help of this Joystick Module, you can measure position coordinates on the X and Y axis by moving the “hat”. It also contains a switch that is press-able by pushing the “hat”.It also contains a switch that is press-able by pushing the “hat” down. Similar to the PS2 controller. The X and Y axes are two 10k potentiometers which control 2D movement by generating analog signals. When the module is in working mode, it will output two analog values, representing two directions. This module uses the 5V power supply, and value, when reading through analog input, would be about 2.5V, a value will increase with joystick movement and will go up till maximum 5V; the value will decrease when the joystick is moved in other direction till 0V.

This is CH340G USB To TTL(Serial) Converter, USB to TTL / USB-TTL /STC microcontroller programmer / PL2303 in nine upgrades plate with a transparent cover Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc. This USB–TTL converter is based on CH340G USB to Serial TTL converter chip. The module can be used for 3.3V logic level signals, the and has the option to switch from 5V to 3.3V logic level using a 2 pin shunt supplied with the module. The CH340 USB to serial adaptor makes use of the CH340 USB to serial IC to provide a low-cost alternative to our popular FTDI based module. Although much cheaper this module doesn’t lack in features or usability. Once you have installed the drivers the module will appear as a normal serial COM port on your computer making it compatible with most terminal programs and development environments such as the Arduino IDE. The module includes a small switch which allows the voltage available at the VC (Supply output) pin to be switched between 3.3 and 5V. Data pins include TX, RX. These digital pins are at 5V TTL levels allowing them to be directly interfaced most 5V microcontrollers. Specifications Resources Datasheet Tutorial
