arduino gear motor Gravity: DC Micro Metal Gear Motor w/Driver For Arduino - 30:1 [discontinued]An ordinary DC motor requires an H Bridge to work with a microcontroller such as an arduino UNO. For newcomers to electronics, the process of finding the right motor driver, connecting it to the MCU and learning the relevant electronic theory can be confusing and frustrating when you just need something to work quickly. We hope that using the DC Micro Metal gear motor changes this. The new micro DC geared motor is easy to operate using the DFRobot
An ordinary DC motor requires an H Bridge to work with a microcontroller such as an arduino UNO. For newcomers to electronics, the process of finding the right motor driver, connecting it to the MCU and learning the relevant electronic theory can be confusing and frustrating when you just need something to work quickly. We hope that using the DC Micro Metal gear motor changes this.
The new micro DC geared motor is easy to operate - using the DFRobot "Gravity" interface, you are able to control the motor using only one control signal. Easily implement forward/reverse control and speed control via PWM. This motor also combines the features of a DC motor and 360 degree servo. We have also increased the stop range and reduced standby power consumption, so the current draw is less than 1mA without signal control. The Arduino Servo library supports up to 12 motors on most Arduino boards and 48 on the Arduino Mega. More fucntion could be found on Arduino Servo page. Ideal for DIY projects!
NOTE: The embedded control chip will consume a small amount of the input voltage, therefore the motor voltage will be slightly reduced. The motor speed will also be slightly slower than the rated motor speed.

Phenomenal
Format: Kindle
Truly a wonderful read. I picked it up after absolutely falling in love with her latsest novel 'Our Perfeect Storm' (another good read), convinced that Carley Fortune is going to be the next big thing in romance. After finishing this book, im a believer. Its filled with tension and heartbreak, and laughter. It made me sob, it made me giggle, it even made me a little giddy. I could not put it down, and I'm sure you wont either, if you're already here.

Not my favorite by her
Format: Paperback
I have to say that Carley Fortune can write a really beautiful love story. I enjoyed this one but not nearly as much as This Summer Will be Different.
Sam is absolutely precious and his brother Charlie is trouble with a capital T but in the funniest and sweetest way (for the most part). And Percy's journey from 13 to 30 is a nice development throughout.
I enjoy the multiple timelines and to see Percy and Sam's love for each other grow from meeting the summer they turn 13. This story is both heartwarming and heartbreaking at the same time.
SPOILER: DON'T READ FURTHER IF YOU DON'T WANT ANYTHING SPOILED!!!
I was ready to give this book at least a 3.5 ⭐ until the cheating with the brother. Of course it was a one time regrettable mistake, but I am auto out on a cheating trope. And making it with his brother just sets the relationship up for failure no matter how many promises of forgiveness. But that's just my opinion. So be warned.

Such a good read
Format: Paperback
This is the absolute cutest book. I’ve read in a very long time! If you were someone growing up in the early mid 2000s, you are going to love this book, it hits all the nostalgic spots, and it makes you really think about your childhood again… I give it a 10 out of 10 highly recommend it super cute read. I read it in like five days between work and other things I had to get done.

Perfect for Homeschooling!! Let the stories come alive and captivate you!
Format: Hardcover
I’m a homeschooling mama and I’m grateful for men like Eric Metaxas who are personally invested in the wellbeing of our nation. Thank you, Eric, for sharing history with truth and the fear of God.

A Revolution of Faith and Freedom
Format: Hardcover
Eric Metaxas’s Revolution: The Birth of the Greatest Nation in the History of the World presents the American founding as far more than a political dispute over taxes or power—it is portrayed as an epic struggle between liberty and tyranny, virtue and corruption, good and evil. Through vivid storytelling and rich historical detail, Metaxas casts the Revolutionary era as a moral drama in which ordinary men were called to extraordinary courage against overwhelming odds in their fight for freedom. The book compellingly shows how patriots like Samuel Adams, Patrick Henry, John Adams, Abigail Adams, Benjamin Rush, James Otis, Henry Knox, Paul Revere, John Hancock, Thomas Paine, George Washington, Martha Washington, and others, understood the conflict not merely as resistance to British overreach, but as a defense of God-given liberty against arbitrary, and often brutal, power.
A particularly striking theme throughout the book is the Founding Fathers’ deep reliance on Divine Providence. Metaxas highlights how many believed that human rights flowed not from kings or governments, but from God Himself, and that the outcome of the Revolution ultimately rested in His hands. Prayer, biblical conviction, and appeals to Providence are woven into the narrative, reminding readers that the Founders often saw themselves as instruments in a larger story unfolding under God’s sovereign care. Indeed, Providence often revealed His hand in altering the weather and divinely guiding the patriots as they fought the British forces. The result is a sweeping and engaging account of America’s birth that frames the Revolution as both a historical and spiritual struggle, fought with courage, conviction, virtue, and faith.
