Yay the comments where wrong(ish)
Half way through and in rooting for you, great teaching btw 🙂
What about feedback with constant voltage output with some sort of voltage divider… Then feed that back into the Arduino as some "feedback" voltage divider type circutry.. regardless if it's pwm or not, … works either way I'd think. Good video. +1
Good,hardware explain 👍👍👍
Hello Julian Ilett, greeting from Indonesia!
Currently, I try to build my buck converter, sadly I haven't succeeded in converting down the input voltage. If you don't mind could you please tell me about what kind of or what type of PWM driver that you used in this video?
your help means a lot to me 🙂
Thank you in advance!
I just realized something. How do I power my buck converter? I need to step down 54 volts (e-moped battery) to 12v max 10 amps. So I am looking arround and sadly many youtubers fallback to the 2576 whicg cannot go high enough and is only 3 amps. I I really want not go the arduino way and you do a great job! But how to power my arduino from that 54 volt battery? Right now the only thing I can think of is to use a lightweight buck converter (I have several XL7015 based 80 volts / 0.8 amps buck converters) but it feels a little silly?
needs capacitors now lol
If you want to crimp that sort of terminal with pretty much any pair of pliers, put it between the handles, all the way up there. Does the job quite nicely, that does…
Would you simplify the circuit with a 555 timer chip? (And a cap at the output)
Now do a video on boost converter!
1,44W on input, 0,95W on output. 65% efficiency isnt great… but works 😀
Send list of components with figures and cost
I would guess that the lamp gets brighter when the inductor is shorted because the power dissipated in the bulb is V^2/R. With pure PWM (inductor shorted) you get bursts of full voltage, whereas with the inductor in circuit, the voltage is reduced—so you lose out from the V squared term. (The R of the bulb does not change very much.) (I would also be very cautious with current readings in PWM mode.)
And what's the mm of the power connector coming from your solar? 2.5mm? 5.5?
