A simple project to interface an old paper tape reader to a Raspberry Pi 3B. I find the C language easiest for me, and the libraries needed, were already installed in my version of raspbian. The Oliver Audio Engineering paper tape reader runs on 5V, but the Raspberry Pi runs on 3.3V.

...Please note that pigpiod may conflict with clock peripheral. When i2s-DAC available( pigpiod uses PWM). Else, PCM is used Default pins: IR/LED Module IR Out: GPIO 17 | Pin 11 Report to IR Receiver Model Specs LED1 : GPIO 27 | Pin 13 LED2 : GPIO 22 | Pin 15 Rotary Encoder Module: PEC12 A : GPIO23 | Pin 16 PEC12 B : GPIO 24 | Pin 18 PEC12 1 : GPIO 25 | Pin 22 LED1 Always ON LED2 ON when PLAY Pins can be changed in /home/volumio/script.volumio.service/addons.py MicroSD cards need to be expanded

Driver for Arduino SEEED Relay Shield. Digital connections to Raspberry pi: * Connect 5v pin to 5v pin from Raspberry pi. * Connect ground to ground. * Connect 2 GPIO pins to digital inputs. * Options: SEEED pins 4 thru 7 operate relays 1 thru 4. Power connections to motor: Wire the motor between the common pins on 2 of the relay outputs Wire the motor power (+) to the normally open pins (NO) of the 2 relays Wire the motor ground (-) to the normally closed pins (NC) of the 2 relays Circuit Diagram: (+PWR)--NC1------NO1----(GND) | (Motor) | (+PWR)--NC2------NO2----(GND) Usage: motor1 = RelayMotor(3, 5) motor1.forward() print motor1 time.sleep(1) motor1.off() print motor1 time.sleep(1) motor1.reverse() print motor1 time.sleep(1) motor1.off()

...ss.digit(4) displays a 4 on the LED. ss.number(1234567890, 0.3) #Displays the number 1234567890 with one digit each 0.3 sec. myled = LED(3) instantiates an LED in pin #3 myled.state=True turns on the LED while myled.state=False turns it off.

Create a two-page A4 PDF containing Raspberry Pi GPIO pinout "leaves" that shows the pin assignments for v1 on one side and v2 on the other side.

...ATmega8 uses its 8MHz internal oscillator to reduce hardware (atmega8 no-xtal bootloader is used). The arduino library uses SoftwareSerial internally to communicate ATmega8 via digital pin 6 (only for uno/duemilanove or clone with atmega8/168/328, not for mega & due). Only one wire simplex serial communication at baudrate 9600 is required to communicate with serialLCD module. The library & firmware file is released in public domain as open-source project. Feel free to edit/improve/share it. *** Raspberry Pi python library added. ...
