For the record I know I am going to get slammed for saying this, so screw it. I know many of you have thought the same thing just never said it to anyone here.
@ DeathBloom, I don’t mean to discourage you, but I have to ask you an others in this same boat.
It’s clear you know very, very little about electronics, and that’s ok, we all have to start somewhere. Why in the world would you jump in both feet into something way above your head? Electronics is not like legos in that if the connector fits another your good to go. Why would you spend your money on something, and have no idea what your really doing?
I am all for people learning something new like you are, but why so many of them try to blink a led, spin a motor without ever at least learning first the absolute basics in electronics, like how to calculate a current resistor for a led or for that matter even know a led has a polarity. Understand current draw on a I/O pin, know what a transistor does and how to use it, and calculate the base current resistor properly. Let alone not own a $8 el’cheapo meter just blows my mind. Many don’t even know that I2C needs pull-up resistors, and moreover what value to use on a 3.3V system compared to a 5V system.
Many more yet that play with I2C and SPI done even own a cheap scope. The copy and paste code examples, plug in these modules and get the gizmo to work and then get all excited and then go full throttle into thinking of something larger to make, and when they do and it does not work they are scratching their heads wondering why it worked on the bench but after i put 50’ of cable to it, it stopped. Then all the forum questions start why this and why that, and did you do this and did you do that. Hey, just pull your scope out and probe the lines and you will quickly see what the problem is.
LEARN BASIC ELECTRONICS first people, and for the love of pete get some testing equipment if you plan to do more than the basics.
I hate it when I see people make things that don’t know jack, and just because it’s working they think all is well. Start selling it to their friends and such and then there is a fire at night because of it.
