Look atFigure 1. It shows a typical general-purpose (NPN) transistor/LED circuit. If you hook up +5 volts to Vcc in this circuit and pulse the input terminal (Vin) with +5V, 0V, +5V, etc., the LED will flash on and off accordingly. Of course, in order to make this circuit fu...
To keep it going, you have to add a little bit of energy on each cycle. In a pendulum clock, the energy that keeps the pendulum moving comes from the spring. The pendulum gets a little push on each stroke to make up for the energy it loses to friction. An electronic oscillator works...
A lot of podcast platforms include a “hook” or short description along with the podcast name. However, don’t get too hung up on this. Make sure to include keywords that make it easier for people to find your podcast, but avoid keyword stuffing or you could be penalized. Choos...

The solder completes the circuit, also allowing current to pass through a second light. Because of electrical resistance, both the solder and the tip heat up very quickly, and the solder melts. Dry skin doesn't conduct enough electricity to effectively complete the circuit, so the tip stays ...
Adding electrical energy to a capacitor is called charging; releasing the energy from a capacitor is known as discharging.Photo: A small capacitor in a transistor radio circuit.A capacitor is a bit like a battery, but it has a different job to do. A battery uses chemicals to store ...
Broadly speaking, if you hook a slab of a conducting material up to a battery, electrons will march through the slab in a straight line. As moving electric charges, they'll also produce a magnetic field. If you place the slab between the poles of a permanent magnet, the electrons will ...
In this lesson we learn the ins and outs of controlling a DC Motor from an Arduino. A key aspect of this is to understand you must not connect a motor directly to an arduino. You need to either build a suitable transistor and diode circuit, or you need to utilize a motor controller,...
Solder the output pin on your regulator (+5v out) to the 5v in on the NES, and attach ground. Use a couple of alligator clips to hook it up to a TV. Plug in a cartridge (Make sure it's facing the right way!), add the battery, and try it out! If it doesn't work, don't...
