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.
Here is a fun project you can do with your kids. It’s a project box with battery, switches, LEDs, vibrating motor, and whatever else you can come up with. it uses header pins and jumper wires to enable the user to connect circuits.
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.
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.
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.
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.
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.
An LED or Light Emitting Diode is a low power semiconductor light source used in lots of electronic devices. LEDs are closeley related to transistors and regular diodes.
A diode is a semiconductor that only allows current to flow in one direction, it is a one way valve …
A Resistor “resists” current flow. Think of it as a restriction or a water valve that is stuck in a …
