We found 2 great tutotials at the below links:
Package includes:
Description:
1. The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0V to 5V pulse. (or 0V to 3.3V pulse if you solder SJ2 closed on the EasyDriver)
2. EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor.
3. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4, 6, or 8 wire stepper motors.
2. EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor.
3. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4, 6, or 8 wire stepper motors.
4. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the micro stepping resolution. The sleep and enable pins are also broken out for further control.
Features:
1. MS1 and MS2 pins broken out to change micro stepping resolution to full, half, quarter and eighth steps (defaults to eighth)
2. Compatible with 4, 6, and 8 wire stepper motors of any voltage
3. Adjustable current control from 150mA / phase to 750mA / phase
4. Power supply range from 7V to 30V. The higher the voltage, the higher the torque at high speeds
5. Distribution pin, not welded, this module is open source
Note:
Do not connect or disconnect a motor while the driver is energized.This will cause permanent damage to the A3967 IC.

Adafruit Monochrome 0.96" 128x64 OLED graphic display (Ada OLED 0.96 display)
Cables not included
Description:
These displays are small, only about 1" diameter, but very readable due to the high contrast of an OLED display.
Description:
These displays are small, only about 1" diameter, but very readable due to the high contrast of an OLED display.
This display is made of 128x64 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!
This breakout can be used with either an SPI or I2C interface - selectable by soldering two jumpers on the back. The design is completely 5V-ready, with an onboard regulator and built in boost converter. It's easier than ever to connect directly to your 3V or 5V microcontroller without needing any kind of level shifter!
TheRaspberryPiGuy has done an *excellent* video on getting this display running with your Pi.
Guy Carpenter has a guide for using OLEDs like this one with the Raspberry Pi it's well worth a read!
Using this display with a Raspberry Pi? Check out Adafruit's SSD1306 OLED display guide.
Adafruit have provided a detailed tutorial and example code in the form of an Arduino library for text and graphics. You'll need a microcontroller with more than 1K of RAM since the display must be buffered.
On the Raspberry Pi, Adafruit now have a Python library available that works with these displays in both i2c and SPI mode.
You can download the Adafruit SSD1306 OLED display Arduino library from github which comes with example code. The library can print text, bitmaps, pixels, rectangles, circles and lines. It uses 1K of RAM since it needs to buffer the entire display but its very fast! The code is simple to adapt to any other microcontroller.
TECHNICAL DETAILS
Dimensions:
- PCB: 38mm x 29mm (1.5" x 1")
- Screen: 25mm x 14mm
- Thickness: 4mm
- Weight: 8.5g
- Display current draw is completely dependent on your usage: each OLED LED draws current when on so the more pixels you have lit, the more current is used. They tend to draw ~20mA or so in practice but for precise numbers you must measure the current in your usage circuit.
- This board/chip uses I2C 7-bit address between 0x3C-0x3D, selectable with jumpers

Picade X HAT USB-C (Picade X HAT)
Description:
Turn your Raspberry Pi into a retro games console! Picade X HAT includes joystick and button inputs, a 3W I2S DAC/amplifier, and soft power switch. Nice!
Picade X HAT is now Raspberry Pi 4 compatible, with USB-C power!
This HAT has all the same great features as the original Picade HAT but now has no-fuss female Dupont connectors to hook up your joystick and buttons.
Simply pop Picade X HAT onto your Pi, plug a USB-C power supply into the connector on the HAT (it back-powers your Pi through the GPIO, so no need for a separate power supply), wire up your controls, and install our driver! It's ideal for your own DIY arcade cabinet builds, or for interfaces that need big, colourful buttons and sound.
Features- I2S audio DAC with 3W amplifier (mono) and push-fit terminals
- Safe power on/off system with tactile power button and LED
- USB-C connector for power (back-powers your Pi)
- 4-way digital joystick inputs
- 6x player button inputs
- 4x utility button inputs
- 1x soft power switch input
- 1x power LED output
- Plasma button connector
- Breakout pins for power, I2C, and 2 additional buttons
- Picade X HAT pinout
- Compatible with all 40-pin Raspberry Pi models
The I2S DAC blends both channels of digital audio from the Raspberry Pi into a single mono output. This is then passed through a 3W amplifier to power a connected speaker.
The board also features a soft power switch that allows you turn your Pi on and off safely without risk of SD card corruption. Tap the connected button to start up, and press and hold it for 3 seconds to fully shutdown and disconnect power.
SoftwareWe've put together a simple one-line installer that'll get everything set up on your Picade X HAT, the controls, safe shutdown, and audio. Open a terminal and type curl https://get.pimoroni.com/picadehat | bash to run the installer. You'll need to reboot once the installation is complete, if it doesn't prompt you to do so.
Our software does not support Raspbian Wheezy
NotesWith USB-C power connected through Picade X HAT you'll need either to tap the connected power button or the button marked "switch" on the HAT to power on your Pi.
