@michael-taggart , It appears that your circuits, both of them are using an RGB Led, that is, an LED that incorporates 3 leds into one package...a ...

@michael-taggart , HI Michael..and welcome to the forum! As DroneBot workshop,@bill, our forum host as alluded to, there are many software solutions...

@zander Looks like your on your way.. The idea of taking it a chunk at a time is a good one.. It won't seem so intimidating after you get a few hour...

Welcome to the forum @greggatshack... You will find there are quite a few of us "old guys" on this forum, and with varying degrees of experience and s...

@pajhum42, Indeed..as a noobe, there is a lot to learn about basic electrical and electronics theory and application..don't get discouraged, it takes ...

@pajhum42, HI...just following your post, and I found this link that I think should help you with both problems of how to use a transistor with an Ard...

@inq , After I had posted my last response, I did a little research and found this link: It's a how to make a 915MHz LORA antenna, various types...

@inq Correct.. no there is no reasonable ability to "tune" at the higher frequencies because of the things you already mentioned..The science of anten...

@inq , Your quite welcome Dennis...Yes, as you can see, while the principal theory is complex, the actual implementation of aerials (antennas) are str...

@inq . I found this explanation of how power in an antenna is radiated into radio waves. the resource link can be found at: regards, LouisR

@davee , thanks for the information that those not as familiar, and as usual, you are spot on.. and hence I defer to the data sheets for determining ...

@davee, Indeed, you hit the nail on the head.. Yes @inq, impedance matching in antenna theory is based on the fundamentals of reactance plus circuit...

@ander (RON), I see your point.. so I'll recommend that you try using Logic level mosfets like RFP30N06LE with a Vgs (th) of 2V, and a 2N7000 with a V...

@zander (RON), yes I understand that, and there's a little math involved in doing that..so here's a link to how to figure that out.. Your right ab...

Welcome to the forum @pajhum42, (Peter)... Yes, electronics is a tough subject matter to tackle, but the good news is that if your really interested...
