This open-hardware #microchip PIC16F1459 #microcontroller development system is designed to let learners go below the level of #Arduino and #pico systems to build deeper knowledge of hardware programming and interfacing. And, with a variety of components already on board, no breadboarding is required! Check it out: https://mirobo.tech/ubmp4
Content warning: Electronics question – LED resistors, boosts welcome
I pulled apart an LED bulb. I can't remember the lumens but think it was 200lm. I want to use the individual LEDs with an Arduino but don't know what resistor to use with each as I'm not sure how big a punch each one packs. The resistor for all 36 tiny LEDs is in the second photo – looks like [brown black black black red] to my eyes.
Any idea how I can calculate the resistor needed for one bulb please?
In the #UK it's not always sunny enough for one of these to be useful, but I've hooked mine up to a #DIY #battery pack—made of #recycled #liions—and while it's basically useless on a cloudy or rainy day, it actually provides a meaningful amount of power on a sunny day.
This would never work as a commercial product because, if these components were all brand new, it wouldn't make any economic sense.
