A transistor is a semiconductor device that is commonly used as an electronic switch in circuits. Transistors are like electronic switches. They are both useful in simple applications, like using a single transistor to allow a Raspberry Pi to control a device that requires a lot of current to operate, Read more…
Push buttons are commonly used in circuits to turn on a component while pressed or give signals to a microcontroller via GPIO pins. Push buttons have four different pins, with two on each side. The pins that are across from each other are internally connected. This means that if one Read more…
Light Emitting Diodes, LEDs, are a special kind of diode. Without going into the specifics, a diode is a semiconductor that only allows current to flow through it in one direction. LEDs also only allow current to flow in one direction. However, they are different because they emit light as Read more…
Resistors are used to reduce the amount of current that flows through a circuit. All electronic parts in a circuit have a recommended operating current. This is the amount of current needed for that part to work properly. If the current flowing through the circuit is significantly lower than the Read more…
Batteries are the power source of many circuits and provide the electricity that flows through a circuit. They have a negative and positive terminal on each end. The electricity exits the positive (labeled) terminal of a battery and returns back to the negative (labeled) terminal. In reality, the electricity is Read more…
Published by Raymond Alvin on 1/7/21 Voltage (V) Voltage is the potential difference in a circuit. It is like potential energy or electricity that can go through a circuit. It is possible that all of the voltage supplied to a circuit will go through the circuit. However, this will cause Read more…

Posted by Raymond Alvin on 12/2/20 Apple has been making its own chips for their iPhones, iPads, watches, and headphones for quite a while now. However, they have been using Intel’s processors in their Macbooks for a long time as well. Recently, Apple announced their transition to Apple Silicon. They Read more…
Published by Raymond Alvin on 11/30/20 With the recent release of the Model Y in March, Tesla’s stock has been booming. The company seems to be doing better than ever with a market cap of $466 billion. Elon Musk has stated many times that he wanted to create a car Read more…
Published by Alex Seamark on 11/26/20 Jet engines work by sucking air in and exhausting it at high speed to generate thrust. This article will go into depth of the workings of a jet engine. First, the fan sucks air in at the front where it is then directed to Read more…
