How To: Build a PWN circuit to control power that can dim an LED, control a motor etc.

Many types of circuits are useless and less useful if you cannot control the amount of power going through them. For that, you need a PWN (pulse with modulation) switch. This electronic component will let your control the power going through the circuit, enabling you to dim LED lights, control the speed of a motor, and other useful tasks. This video will teach you all PWN switches and how tom make your own.

How To: Program a $6 NodeMCU to Detect Wi-Fi Jamming Attacks in the Arduino IDE

Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.

How To: Make light using a stepper motor generator

In this tutorial, we learn how to make light using a stepper motor generator. First, take the motor out of an old printer that you don't use anymore. After this, find a few LED lights. You will need to solder the LED lights, then connect them with a soldering iron to the printer motor. Now connect these to a generator, and the light should now shine so that you can see in the dark! This won't use any additional electricity, so you are helping the environment. All of the pieces used to make th...
