Stepper Motor with Raspberry Pi

https://learn.adafruit.com

Stepper motors fall somewhere in between a regular DC motor and a servo motor. They have the advantage that they can be positioned accurately, moved forward or backwards one 'step' at a time, but they can also rotate continuously.

Voltage Divider Calculator

https://circuitdigest.com

A potential divider circuit is a very common circuit used in electronics where an input voltage has to be converted to another voltage less than it. This circuit is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of Resistors.

Programming an ATtiny84A from Arduino

https://www.sparkfun.com

I’m currently working on a project that requires a cheap, low-power microcontroller that’s programmable through Arduino and has a few more pins than the ATtiny85. That’s where I found the ATtiny84A. It has many of the same features as the ATtiny85, but has 12 I/O pins instead of six.
