Hello to all those in this community. I teach HS physics and Chemistry and since our admin has insinuated we shouldn't "hold our breath" for long overdue and much needed funds to purchase very fundamental/basic equipment needed for our newly renovated laboratories(spent all the $ on the labs and nothing left for anything else). I am fairly skilled in fabricating nearly anything and using most materials(metal, wood, glass, etc) but I do very much lack any coding skills. I'd recently purchased a few arduino kits(Elegoo Mega Kit) and I'm hoping to build a few things over x-mas break but need some ideas for where to find some of the best resources to learn how to do the "basics" for a handful of projects. I'm not digitally illiterate, as I am fairly capable of automations, workflows, etc, and I'm quite apt with most things other than coding. I'm hoping to build the following if possible: -frequency generator -benchtop DC power supply(nothing over 12-16v and maybe 2a) -mechanical wave driver -mini speaker amplifier In the future: -digital pH meter -oscilloscope -electrostatic generator -jacob's ladder -much more. Any help would be incredibly helpful. I believe I just need a basic tutorial for how to initially upload the code required from my macbook to the arduino component so that it performs it's desired function. Thanks in advance and I will post my builds as I complete them if anyone is interested(assuming they work)

[image] molsen81: I believe I just need a basic tutorial for how to initially upload the code required from my macbook to the arduino component so that it performs it's desired function You could start with https://www.arduino.cc/en/Tutorial/HomePage and for your MEGA https://docs.arduino.cc/hardware/mega-2560/ for your projects, you will likely need more components / sensors (and You won't build a benchtop DC power supply from your MEGA - a phone charger and a boost converter could do).

Here is your homework. :wink: [image] Share tips you have come across General Electronics Arduino links of interest.

For a function/frequency generator look for an AD9833 module. With the typical 25MHz crystal it will generate signals up to 12.5MHz. Sine waves are good to about 3MHz - it takes a vivid imagination to call two points a sine wave. Modules cost in the $10-15 range. The are projects with Arduino code on the internet. AD9833.pdf
