How to make an LED driver circuit
HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It’s because of a heart condition I suffer from called Congestive Heart Failure. Here’s a link to some information about CHF: https://cle.clinic/2TdS2Ux
One of the symptoms is that is causes fluid retention, mostly in the hands, feet/ankles, and face.
It will kill me one day. I’m doing ok right now, but someday…

LED Current Controller – Dimming/Brightness (BJT Constant Current Limiter)
Why drive LEDs with constant current? How can we limit current with 1 transistor and 3 resistors?
CircuitLab circuit: https://www.circuitlab.com/circuit/n66p5c9y3qn9/ledconstantcurrentcontroller/
In this video tutorial we are going to be building a current controller for and led by using a BJT or bipolar junction transistor. We briefly talk about the relevant properties of a BJT, and then walk through several simulations in order to determine the correct resistor values for our design current.
The simulations we run include a DC simulation, a DC sweep sweeping two separate parameters, and a DC Sweep using a parameterized variable in our circuit. We show how a simulation can be a powerful tool for iterating on a design and to gain intuition for our real life circuit.
If you have ideas about other tutorials you would like to see us do please let us know in the comments.
