If the diode is good only led 2, or led 3 will light, but not both. If the diode is shorted, but leds will light. I have tested some power transistors with this circuit, like the2N3055. Some power transistors have an internal clamping diode, such as the ones used in tv flyback tr...
. For example, if you have a battery that powers the Arduino and a battery that powers the DC motors, the ground (negative) terminals will need to be connected together so all of the components are connected to the same ground. This is known as having a common ground in the circuit....
The LED will light up when you get the magnet very close to the Hall Effect Transistor and Circuit. In some cases you will have the circuit connected correctly the magnet might not be strong enough. I had to use my handy multimeter to get this information, I was...
1) LED Driver Circuit Use Case: Controlling high-brightness LEDs beyond Arduino's 20mA limit. Vin (5V) → 220Ω resistor → Base Collector → LED → 100Ω → GND Emitter → GND Formula: RB = (Vin - 0.7V) / (ILED / hFE_min) 2)Audio Preamplifier Gain: AV ≈ RC / RE (Typi...

Here's a quick rundown on how to utilise a 2N3904 transistor in a basic circuit: Determine the pins: The 2N3904 transistor has three pins: the emitter (E), base (B), and collector (C) (C). Typically, the emitter is linked to earth, while the collector is connected to the load (...
For JFETs, the Arduino measures the cut-off voltage. It sets the load voltage to 6V then gradually increases (negative) Vgs until the current through the load is less than 1mA. Step 3: The Circuit Here is a brief description of the circuit. A more complete description is in the attache...
The opposite of the low-side switch is the high-side switch. This transistor connects between +V and the load. Because of how transistors work, these can be a little more difficult to use in an Arduino or Raspberry Pi circuit. Typically these use a PNP BJT or P-Channel MOSFET. ...
