Have a schematic that has some holes in it (resistor / diode / capacitor / LED values) that I need someone to figure out and show me how to get it to work with an Arduino. Basically consists of 2 band pass filters, LM358, etc. ... Basically consists of 2 band pass filters, LM358, etc. Also need that person to look at my Arduino code and fix it up so it works. Only seem to get one reading and then it doesn't refresh / take another reading. ... Really needs someone that has built something like this before (so you know how they work) and that can get my schematic and Arduino code to work. Also happy to take suggestions if you have a better way to build one of these that works.

For a project, I need to control the speed of a DC motor using an Arduino Uno. The circuit would need an AC to DC converter, as this motor would be powered off 120 VAC. ... The deliverable for this project would be a bill of materials, circuit diagram, and code for the Arduino. I don't think this is a difficult project, but I do need it completed quickly.

Looking for someone who has experience in Nextion HMI displays. I have finished code that needs to be displayed on the screen. Also I will need some code written and added. More details will be up tomorrow. But if you have any Nextion HMI experience and can show work or prove it through a general "test" you will be my first pick.

We have internally developed a mineral processing system which presently operates under manual control, but have also wired the system to 8 arduino's in a PC to monitor and control factors such as PH, ORP, temperature, fluid controls, etc. ... Our requirement is for the initial programming of the arduinos to monitor, display and record all operational parameters.

I require a script to make a self opening, fingerprint operated door with an arduino and needs to run as follows: 1. When either, or both of two GT-511C3 fingerprint scanners are recognized, this will actuate one towerpro micro servo to turn 45 degrees (to unlock the door), then back to the original position. 2.
