Bunch way back when I learned to program, first in BASIC, then Pascal, I was taught to comment not just what the code does but why. that way when you come back to it after working on other projects you can jar your memory as to what you were thinking.
Excellent video! I have a question if you wouldn't mind. I've followed your setup to the letter. How would I go about modifying the code to charge a 9 volt rechargeable battery? I don't think I need to modify the hardware, when I plug the 9v in the power on the OLED goes way up but it doesn't change to "charging" at all. Thanks in advance.
Nice project! You could make it more interesting by using that unused OLED space to show the accumulated charge, the charge time, the voltage (from the INA219) and the battery internal resistance.
Soon buddy, soon I promise. Things are getting crazy around here. I have two major sponsors coming on board. So lots of cool new ideas and videos coming up.
I just don't know what Im asking. I am trying to build for a 4.8v NiCa battery pack. A cheap version that's made in china. You've mentioned in the description that with constant current mode, different setup may be charge. So, this will work with up to what number of battery? I am confused if that charging voltage should be greater that the battery pack that I am charging since you mentioned it can with constant current mode. Thank You for the circuit.
Very cool video. I like it. Do you think you will ever build this into a 18650 charger? Also, if I wanted to charge two NiMh batteries hooked in series, could I just step up the voltage? I'm asking because I have no desire to let any magic smoke out or burn my lab down.
BEAUTIFUL! KUDOs to you. I am a newbie in Arduino and got attracted to charging and discharging 18650. I also viewed your INTERNAL RESISTANCE project. I LEARNED A LOT. THANKS
2n4401 is an NPN and using this on the high side of your load. which means you have to drive the base harder to get above the emitter? wouldnt this be better with the NPN on the low side of your load in a normal switch configuration. also you have no current limiting resistor on the base which could lead to issues
I like how clearly your code is laid out. Makes for easy debugging.

Javier Palla Lorden thanks...ideas for part 3. specially the mAH
Looking forward to part 3!
Hi, still waiting for part 3.......... :-)

@@learnelectronics Did you ever follow through and finish the series? I couldn't find any thing in your video listing.

+EXALLIEVI DI DON BOSCO, NCR GROUP, PH Thank you so much
I like that bit:
if(pwmRate
How do you know when the battery is charged? Is the current goes negative? Or do you check voltage?
Hi Paul, I can't fine the sketch for this battery charger on you web page. Is that file removed ?
What is the power supply you use? and, can this be used to charge a 6v NiCd battery?
Don't you have the circuit diagram anywhere?
Is it safe to Provide unfiltered Charging pulses to battery..? does not it lowers the battery life ?
Hi, firstly i m newbie at arduino things, i couldn't find the ino file of v2 at dropbox. and is the LM2577 suitable for power supply?

How can i see the battery charging percentage?
Amazing video ! ! I am really interested to for create a 12v, 100AmpH charge controller using this concept. Really nice.
Can you send me circuit dragram ?
How can you do that?
Sir please the type of Transistor what is ? Tanks..
And sketch for this version.. nimh charger v2.. tanks sir
Hello Paul, trying to replicate your charger. Any news on the spec of the presented transistor? Thanks
How to control battery from overcharging and over discharge
This isn't -dV
Im using Avasva instructions to make it and I do it already :)
Can you send me circuit dragram ???
where the code?
