It is necessary to change part of the code that is written in C, for arduino nano. Now that device monitors the 0-5V analog input, it needs to be modified to read pulses (frequency). The device is fully developed, schematics and PCB. The code must be maximally optimized so as not to affect the speed of the device.

I'm hoping you could help write some Arduino code that will download a gif from a static URL and then display it on an LED Matrix. I have this kit from Adfruit, , and the board has WiFi and can run Arduino. It meant to connect to the LED Matrix that comes in the kit. Adfruit has a tutorial and some code for getting the board to play gifs, but it only plays gifs from the local storage. As stated, I'd like to download and display gifs on the fly. I've been able to get the tutorial to work but would like to have the program check a URL and download the gif then display it on the LED Matrix Tutorial: Code for Displaying Gif:

I’ve had some code written recently for an Arduino UNO R3 that has two inputs. A dry contact and a ultrasonic range sensor. The issue I’m having is that if left alone for several hours it seems to freeze and not work until we have rebooted it using a power cycle. Any ideas on how to prevent this malfunctioning? I can’t share the file with everyone here but will obviously share this with those that have shown they have a lot of experience in Arduino UNO R3 programming. It would be beneficial to know if you have a solid idea as to what may be happening instead of a “Let’s try this or let’s try that” hoping that something will solve the issue.
Motion control of 3 axis machine using an arduino based controller The freelancer will have to develop the logic of finding the target middle point using the system. He will have to find a way to scan a known object using a sensor, and to use the controller SDK to move the 3 axes to scan the object. It involves decent knowledge on motion systems, a creative mind and good c programming skills The project needs someone that can think out of the box. A maker that controls software and mechanics. Creative enough to create a robust system with minimal hardware

...either a MacOs(written in swift) application or Arduino code. Some notes on the required protocol involved: The Industrial device that we want to communicate with is a mod bus slave, and looks for a mod bus PLC Master(server) on the TCP/IP network. The industrial device has a piece of software that tells it what IP address to use for searching for the PLC it expects to find. The Industrial device is looking for the PLC to have registers available to store some small bits. The industrial device needs to read some registers(the requests from the PLC), and post updates to some other registers (status of the industrial device for the PLC to read). The task will be to make a piece of macOS Swift software (using other libraries or not) OR use an Arduino program to provide...

Hi there. I wish to develop a game for Arduino ESP32. I am having a developer design the PCB. Here is a full, detailed explanation of the game. Please let me know if you have any questions regarding it, as could be a bit difficult to understand. Here is a video that shows an *old* version of the game in action, which is incomplete and a prototype, but showcases the basic features of it: This must be done perfectly! The game should not require Internet access to work, this should be OPTIONAL. So, if the establishment has WiFi then we connect the server but otherwise we turn it off. Please let me know
We have an arduino uno micro controller with a H bridge shield driving a solenoid. I need the core of the solenoid to oscillate at a fast rate in and out, unfortunately my coding experience is fairly limited so I have hit a stumbling block.
