Receive data from a small webserver and update buttons on a page
I have a small microcontroller webpage with some buttons. The buttons send JSON data when pressed so the server can act on it. The webpage also needs to receive data from the server when requested and update the buttons state. ( when the page has loaded and when the buttons have been pressed e.g. ) The basics are working - cobbled together from examples. I'm not a Javascript / web programmer so need help in this part.
.Net code for RF Xbee module
I need help finishing a project for Visual Studio 2022, windows form in C#. Im using Xbee RF modules from Digi.com (XB3-24Z8PT) to communicate. I was able to do it using the XCTU software from Digi. One Xbee is the “Master” connected to PC via USB port and the other modules in the same network (same channel) are sending string data like: “hello world”. Everything works fine but I need to implement this on Visual Studio C# .Net windows form. I was able to create a form to open the port using SerialPort.Open Method. But I don’t know how to add the remote modules to send the data and display on a textbox. Maybe I need to add a library file or something else. The remote modules have a microcontroller transmitting (sending) the data.
LED Matrix Sign displaying speeds from a RADAR module
We are looking at options for controlling the speed of Junior Kart racers entering the pits at our local race track. The scope is to identify a suitable coast effective radar module and identify a suitable readily available LED matrix display controlled by an Arduino type microcontroller, describe the wiring and provide the code to allow us to detect kart speeds at a distance of around 10m to 30 m and display it on an LED matrix to inform the drivers and marshals of their speed. We only need three hardware to specified and the software written with general wiring descriptions. We will then build and enclose the electronics as we see fit. happy to discuss options with anyone interested in helping. Manu thanks.

PCB design required for water sensor
I would like a PCB designed with relatively simple purpose. It will act as a moisture sensor, i.e. when the sensor is submerged it is active, when not submerged inactive. The majority of the time, the unit will be asleep. When sleeping it needs to consume minimal current, i.e. tens of micro amps or less. On the rising or falling edge from the sensor (i.e. rising edge = sensor is submerged, falling edge = sensor is now dry), the unit needs to wake up, send an SMS message, and then go back to sleep. Components: -GSM module (e.g. SIM800/900) -Microcontroller with low powered sleep -External moisture sensor -Power circuitry (power source will either be alkaline batteries, or 3.7v lithium cell) Features: - As small as possible - Microcontroller ideally Arduino bootloader compatible - Initial through-hole design (using suitable GSM module)

Design High Power Circuit
Design a circuit that can take input pulses from a microcontroller (most likely arduino), and use that to create high current pulses. This will be the heart of an Arc generator for an Electric Discharge Machining machine. Also recommend specific components and create a circuit board file that I can send to a manufacturer for fabrication. I'd like it to include everything from the A/C input to the high power pulsed D/C output. I have specifications I will share. Basically I'm too cheap to pay someone 3k Euros for a pre built generator since I'm good with electronics. But I'm not THAT good, to be sure the circuit is stable & won't die 15 minutes after I turn it on. I may sell these in the future so I'd like to own the design. Also if you're good with reducing un necessary EMF that would help. This circuit will create a lot of EMF by design, so anything that can be done to make it do it's job and avoid any unintended EMF would make the entire project go smoother. It should put out about 30 volts DC pulses at up to 30 amps based on the input pulse voltage, and be able to survive a short circuit. There will be a separate circuit that will monitor voltage at the destination and stop input pulses upon a short, but they will happen from time to time, and the circuit should be able to endure this till the monitoring hardware stops sending pulses. I could write lots more about the machine itself, but this project is about just the pulse generator. I guess I'm writing this to let you know I'm a busy guy, and want this project done ASAP. I'm doing this on a medium budget, and I have very limited hands on time to work on the project. I will probably hire out more electronics related design. I need to integrate at least 4 different circuits off the top of my head, and do it in a high EMF environment, The more advice I can get the better, and the sooner I can get $ flowing in from this the sooner I can work less at my other job yada yada. Yup that's my ending hehe!
TinkerCAD Professhional

Arduino C string parsing "Logo"
Write a program in Arduino C to parse strings of text commands, and call the associated Arduino functions matching each command. This is called "Arduino interpreter for Logo commands". The project connects ESP8266 / NodeMCU microcontrollers with web apps. Commands are sent as strings over HTTP. The ESP8266 receives the strings containing multiple commands. In the loop() the string is parsed and commands are added to a queue. These commands are executed in sequence, or repeatedly in the loop(). Most of the functionality described in the specification already exists. However some of the code is written in JavaScript and executed in the web app. The task is to re-create this functionality in Arduino C. This will greatly improve performance and responsiveness of the the device. See attached doc for full description of the requirements. NB: You must have access to a NodeMCU in order to complete this project. Testing will be carried out on this device. Tags: Microcontroller embedded programmer Arduino electronics engineer robotics
Wireless position sensor (ultrasonic for range detection)
i want a wireless position sensor (ultrasonic for range detection). The sensor will sense the position and it will transmit its data wirelessly to other location. i want a 220V relay to be controlled though data received from remote sensor placed anywhere in home. Basically there will be 2 circuits, one will be transmitter and 2nd will be receiver circuit. On transmitter board there will be an ultrasonic sensor that will detect objects and on detecting any object a signal will be transmitted via transmitter. A receiver circuit will receive that signal and will control relay output. there will be a wifi module that will receive signal from sensor and will transmit. Microcontroller like ESP8266 or ESP32 with wifi module will receive that signal and will control relay
Sensor Interface prototype design Yanmar 3JH4 Marine diesel
I would like to design an interface to read the engine health data (oil and water temperature, RPM, tachometer hours, oil pressure) from a Yanmar 3JH4 Marine diesel engine, using an ESP32 or ESP8266 wifi enabled microcontroller. It should be possible to read the engine data bus directly, or if not, read the sensors directly in a way that is not destructive to the existing setup. I would need to be able to purchase components for the design from online electronics stores such as direnc.net in Turkey where I am located. I have basic electronics skills but would also need some advice building and installing the circuit.
Arduino project created using TinkerCad
I have designed a ubiquitous computing device that I now need to create a prototype for. The prototype must be created on TinkerCad but it also requires some 'thinking outside of the box' as some of the components needed to build my prototype aren't on there. Therefore I need someone who definitely knows their stuff and can find a way around my issues. The link below will take you to the website with all the necessary information needed to build the prototype. I also need the process documenting with screenshots etc. https://circuitdigest.com/microcontroller-projects/arduino-smart-restaurant-menu-ordering-menu-ordering-system I need it done asap so if you could let me know how quickly you think you'd be able to turn this around, I would greatly appreciate it. Thanks in advance. Victoria
