Optoelektronik är komponenter som omvandlar elektrisk ström till ljus, eller ljus till elektrisk ström. De enklaste formerna är en lysdiod och ett fotomotstånd, som avger repsektive reagerar på ljus.

Mer avancerade optokomponenter är kameramoduler och displayer.

  Seriell display 7-segment grön
4-digit 7-segment displays are really neat little devices, it's a shame that they can be so cumbersome to control. Well we've solved that problem by making them a little bit "smarter." The 7-Segment Serial Display combines a classic 4-digit 7-segment display and an ATMega328 microcontroller allowing you to control every segment individually using only a few serial lines. The Serial 7-Segment Display can be controlled in one of three ways: Serial TTL communication, SPI serial communication or I2C serial. You can even program it for stand-alone operation since the ATMega328 comes pre-loaded with the Arduino bootloader! There is also an FTDI header on board and we've provided a hardware profile for the Arduino IDE to make it even easier to program. We've made some layout changes to this design as well which will make it easier to incorporate these into your project. We've moved the power and I2C pins to the sides of the board such that you can chain them together in order to display longer strings of digits. We've also added mounting holes to the boards so you can mount them on standoffs (no more hot glue!) Features: 4 digit green alpha-numeric display with TTL, SPI or I2C Serial Interface Display numbers, most letters, and a few special characters Individual control of decimal points, apostrophe, and colon Selectable baud rate Selectable brightness Baud rate and brightness values retained in non-volatile memory Individual segment control for each digit

  LCD 16x2 vit/svart seriell 5V
This is the latest evolution of our serial LCD. Included on a single board is a 16x2 LCD and an embedded circuit based around a PIC 16F88. The on-board PIC takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware also allows for a number of special commands so you can clear the screen, adjust the backlight brightness, turn the display on/off, and more. Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power (VDD), ground (GND) and RX pins are all broken out to both a 0.1" pitch header as well as a 3-pin JST connector. SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the back of the display to adjust the contrast. Features: Embedded PIC 16F88 utilizes onboard UART for greater communication accuracy Adjustable baud rates of 2400, 4800, 9600 (default), 14400, 19200 and 38400 Operational Backspace Greater processing speed at 10MHz Incoming buffer stores up to 80 characters Backlight transistor can handle up to 1A Pulse width modulation of backlight allows direct control of backlight brightness and current consumption All surface mount design allows a backpack that is half the size of the original Faster boot-up time Boot-up display can be turned on/off via firmware User definable splash screen Dimensions: PCB: 103x36mm LCD: 71.4x26.4mm
