"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.

In 2016, a Comcast user frustrated with slow internet used a Raspberry Pi to tweet Comcast every hour. The bot checked speeds, and if they dropped below what was promised, it sent an automated tweet showing the results directly to Comcast.

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.
