How To Scale A Thermistor for An Arduino

Thermistors And Your Microcontroller

A thermistor is a simple temperature component, basically it is a variable resistor that the resistance changes in it depending on the temperature. Such a simple device needs a few more components and scaling in the microcontroller to give the desired C or F temperature reading.

What is a Peltier Cooler?

Peltier Coolers or Thermal Electric Coolers are used to make things hot or cold but have another cool use.  Apply a heat source to one side and keep the other side cool and the Peltier generates electricity. Read More…

What is a transistor

The transistor is the fundamental building block of modern electronic devices, it is a semiconductor device used to amplify and switch electronic signals.

More simply a transistor is a valve for electricity. In this video I demonstrate the two types of transistors (NPN and PNP) and explain their uses. Read More…

How to Use an Electronic Breadboard

A Breadboard is a must for the electronics experimenter type of person for experimenting activities. It is made up of rows of pins that you can simply press in components and wires and they will be held in by pressure.

What is a Photo Resistor

Photocells, (LDR) Light Dependent Resistor, Photo Resistor, Cadium Sulfide Cell (CdS), all of these names refer to the same thing. Photo Cells are semiconductors that are also resistors that change their resistance depending on the amount of light.

AC vs DC Explained and How to Use an Oscilloscope

I decided it would be easier to explain AC and DC current if the user already knew how to use and oscilloscope. Explaining how to use an oscilloscope is easy if the user already knows what DC and AC current is. I think the video worked out as a fast paced tutorial for both subjects. Read More…
