LiPo batteries
For several of my projects, I'm going to develop a 5v backup power supply. I have a total of 12 Lipo batteries( https://www.apogeeweb.net/electron/the-best-guide-to-volt-battery.html ), each with a 10Ah capacity. All of the cells are brand new and have been charged and discharged five times. So I wi...

Calculating Values for PN2222A LED Circuit
I'm gonna be adding an IR LED to my Arduino Uno and I'm trying to wrap my head around the math used to figure out the exact resistor values needed to use a PN2222A( https://www.apogeeweb.net/circuitry/pn2222a-small-signal-npn-transistor-datasheet-pdf-download.html ) transistor to drive the LED. I kn...

DS18B20 sensors data not appearing
I have two DS18B20( https://www.kynix.com/components/DS18B20-Digital-Thermometer-Block-Diagram-Datasheet-Features.html ) connected through 1-wire, I can see data coming from them on SSH ls -l /sys/bus/w1/devices/ and they're registered inside my code, addresses are visible. However, data isn't appea...
