"The next time I design something, I'll leave extra room for wiring.", I lied to myself the last time I designed something.

Just a few more components to jam into my new handheld computer before I can wire it!

I call it the 'Grenade', because it looks a bit like a Grenade when you're holding it.

Abandoned project to create a little mini theater using an old HP plotter and electromagnet connected to a raspberry pi. (Old Guy does stuff but doesn't always finish them.)

[Video Description: hands typing on a rainbow-lit clicky clacky keyboard, resting on the bottom half of an open black faux-leather clutch, the top half of which has a 4 inch-ish white e-paper screen and a Raspberry Pi module plugged into it. The keys clack and flash as they're typed, and the camera zooms in on the screen where it says "hello happy pi day!!! :D", as an excited and silly-deep voice offscreen says "It works!" End V.D]

I finally have q new-fangled typing machine! A ZeroWriter RasPi compiled together in a freebie handbag that one could say...came thru in a clutch...?

A4988 Pinout: A Comprehensive Guide

Discover the functionality and versatility of the Stepper Motor Driver Module A4988 Pinout, a crucial component in the world of robotics and automation. Let’s delve into the key details, with a specific focus on the A4988 pinout for a clearer understanding.

Stepper Motor Driver Module A4988

The A4988 is a stepper motor driver module that plays a pivotal role in controlling the precise movements of stepper motors. Whether you’re working on a 3D printer, CNC machine, or any other project requiring accurate motor control, the A4988 is a go-to choice.

A4988 Pinout Configuration

Understanding the A4988 pinout configuration is essential for effectively integrating the A4988 into your projects. Here’s a breakdown of the key pins:

MS1, MS2, MS3 (Microstep Resolution): These pins determine the microstep resolution, allowing you to set the stepping mode for the stepper motor. Configuring these pins enables fine-tuning of motor movement.

VMOT (Motor Power Supply Voltage): Connect this pin to the motor power supply voltage (typically 8V to 35V) to ensure the proper functioning of the stepper motor.

GND (Ground): Establish the ground connection by linking this pin to the ground of your power supply or microcontroller.

VDD (Logic Power Supply Voltage): Provide the logic power supply voltage (typically 3V to 5.5V) to this pin to power the internal logic circuitry of the A4988.

DIR (Direction Input): Control the direction of the stepper motor by connecting this pin to a digital output on your microcontroller.

STEP (Step Input): Trigger individual steps of the stepper motor by connecting this pin to another digital output on your microcontroller.

RESET (Reset Input): This pin resets the internal translator circuit, and it is optional to use.

SLEEP (Sleep Input): Putting the A4988 into sleep mode is achieved by connecting this pin to a digital high signal.

I think I finally found a solution to a lot of my problems with posting the cards each year. Raspberry Pi might be coming to the rescue if I can get two APIs set up exactly like I want. Can't find a service that does what you want? Make your own!
