How to Use a Multimeter - Learn at SparkFun Electronics
basic building block in circuit analysis. By measuring the voltage across the circuit we can see how much voltage each component requires. Let's measure the whole circuit first. Measuring from where the voltage is going in to the resistor and then where ground is on the LED, we should see the full voltage of the circuit, expected to be around 5V.

Serial Peripheral Interface (SPI) - learn.sparkfun
learn.sparkfun.comProgramming for SPI Resources and Going Further Introduction Serial Peripheral Interface (SPI) is an interface bus commonly used to send data between microcontrollers and small peripherals such as shift registers, sensors, and SD cards. It uses separate clock and data lines, along with a select line to choose the device you wish to talk to.
Light-Emitting Diodes (LEDs) - learn.sparkfun
learn.sparkfun.comIf you connect an LED directly to a current source it will try to dissipate as much power as it's allowed to draw, and, like the tragic heroes of olde, it will destroy itself. That's why it's important to limit the amount of current flowing across the LED. For this, we employ resistors.

resources.demco.comsymbol) electricity flows if the voltage exceeds a turn-on threshold (about 1.5V); brightness then increases. A high current will burn out the LED, so the current must be limited by other components in the circuit. LEDs block electricity in the “reverse” direction. Some types of electronic components can be super-miniaturized, allowing
