The DIY Board allows you to create a module from any component with 8 pins or fewer. The numbers next to the feet corresponds to the numbers on the pads. The board has five sections; You can break the sections to make multiple, customized boards.
The NPN Transistor acts as a switch or amplifier. With no current at the base, there will be no current flow from collector to emitter. However, a small amount of current to the base will allow a large current to flow through the collector and emitter.
The Blinker module turns a direct current input into a square wave output, allowing you to make LEDs blink and Buzzers beep. It has a green LED flashing in time with the output and a red LED to indicate if power is connected the wrong way. You can change the blinking rate by turning the wheel!
The Motor module operates between 8V and 12V. By flipping the module around, you can get the motor spinning in either direction. It comes with a soft foam wheel to visualize its rotation, but you can also create your own propellers or paper crafts to put on top!
The USB Adapter module supplies 5V to your circuit when plugged into a USB port. It has a blue LED to indicate that power is being supplied to the module and a red LED to indicate if the module has been shorted.USB cable is included.
