learning cube for arduino

the learning cube for arduino is a helping hand for soft level entry into the fantastic world of (arduino) microcontroller - an easy starting point, away from breadboard confusions ("where do i have to put...?") - assemble, plug it over usb to your computer and start immediately programing

features:

• dht11 - measuring temperature and humidity
• buzzer - audio output
• display - oled display, showing text or graphics
• ldr - measuring brightness
• switch - user input
• tl1838 - infrared receiver (remote control)
• rgb led - mixing colors
• 3x led - red, orange and green...for example traffic light simulation
• poti - measuring analog input
• 8x ws1812b - adressable leds
• servo - plug in a little servo motor

interfacing:

• usb
• i2c
• serial (rxd/txd)

remarks:

• very cost effective (you can built it up for less than 15,-€/pcs, if you could use the china links)
• you can use rgb-leds with common anode or common cathode (switchable on pcb)
• you can use oled-displays with following pinout "vcc, gnd, scl, sda" or "gnd, vcc, scl, sda" (switchable on pcb)
• you can use oled-displays 0,91", 128x64 or 0,96" 128x32
• you can easily order pcb`s by yourself: put (only) the gerber-files in a zip-file and upload it to pcb manufactors ordering interface
• you can download stl-file for 3dprinting the pcb casing (sketchup design files also)

pin assignment:

• A0 = DHT11
• A1 = WS2812b
• A2 = TL1838
• A3 = not connected
• A4 = SDA
• A5 = SCL
• A6 = Poti

• A7 = LDR

• D2 = Switch

• D3 = LED3 (green)
• D4 = LED2 (orange)
• D5 = LED1 (red)
• D6 = RGB LED (red)
• D7 = RGB LED (green)
• D8 = RGB LED (blue)
• D9 = Buzzer
• D10 = Servo
• D11 = not connected
• D12 = not connected
• D13 = internal LED
