Raspberry Pi Kits and Wiring Diagrams and Software
Since the hard part of Raspberry Pi projects is the integration of software to hardware (e.g. the wiring), below are some hardware kits that provide software, but more importantly, provide wiring diagrams for the software.
SunFounder Electronics Fun Kit with 1602 LCD (.pdf on cd) Uses standard python RPi.GPIO library. | $24 | link |
Freenove Super Starter Kit for Raspberry Pi (github) Includes GPIO extension T-board. Uses non-standard python ‘Processing Development Environment’ (PDE) and library. | $22 | link |
JANSANE 16×2 1602 LCD blue I2C, 2 pack I2C (4 wire) integrated with 1602. Uses smbus library. (Owned) | $10 | link |
LED Strips.
Density: 30-per-meter versus 60-per-meter. WS2812 versus WS2801 versus WS2811. Raspberry pi only has 1 PWM output – so cannot play sounds and control the strip at the same time. Note that GPIO Pin 18 is “magical”, not “arbitrary”.
