Measure finger joint angle using IMU sensors (MPU9250) interfaced to Arduino in 3D space

I created 2 different Arduino workable programs on a sparkfun esp32 thing plus C board. I need to have 1 of the 2 programs loaded and executed via OTA from wifi (pc). Only 1 of the 2 programs will be running at time.

I have some basic code written for arduino, running on an Esp32 and NodeMCU. Code measures electricity using the esp32 and controls a relay (hot water cylinder) on the NodeMCU based on electricity measurements (see NodeMCU code attached) I need someone to modify the code on the NodeMCU so that it records how long the relay has been on in the last 48hrs and switches the relay if the cylinder hasn't had sufficient heating. Also, add a manual "heat for 2hrs" function that can be activated on Blynk webpage.

Hi Ahmad, I looked at you profile and maybe you know how to do this project. We make battery packs. And we would like to be able to get data from them remotely. Like cell voltage, charge/discharge cycle and more. This info we can get from the BMS through CANbus. We want this info sent through GSM to (an email for example) in a txt-file. And a simpel software to open the file on a PC to read out the data. We were thinking of a RPi with GSM Hat/modul. Maybe you know other solutions? Software in Python? Regards Marcus

I have a load cell system Details: 157 loadcells (digital scales) are connected to 157 HX711 165 HX711 (157 of them connected and 8 are not connected) The HX711s are connected to 11 MUXs HC 4067 The 11 MUXs are connected to 1 main MUX HC4067 and the last MUX is connected to Arduino Nano. The code was written to another system similar to the above but instead of 165 loadcells (8 not connected) it was made for 192 loadcells, so we need to change it so that it works on the system of 165 loadcells. I can send the operating code and the calibration code to you, you just need to fix both and if it doesn't work, then we can connect remotely to the system through teamviewer and you can fix it. I can send the schematics and a video of the new system whenever I receive your logical off...

We got an already working user interface on an 3.2" inch screen attached to an arduino mega. It's a 3 page devided UI with subpages with products and prices. When a product is brought, a signal is sent via UART to a 2nd mega that activate a relay. The UI's first UI subpage is devided in to 3 x 6 buttons pages, so 18 in total, there is additional 2 pages, page 2 with 2 x 4 product buttons. Then a last page with 2 products. What we need is the following changes on page 1: 1. 3x6 button UI makes things to small, so the UI need to change to 4x4 + 1x2 buttons a page. 2. When one of these above 18 buttons are pushed, everything must happen as it does now, but after the following dialog boxes must pop up with the following text. A. Vaskemiddel? (Yes/ No) B. If No on A...

Need to build a simple game controller with the raspberry pi zero AND pi pico(or just a pi zero), that can play computer games and has computer mouse functionality... I prefer python as the codebase... I'm open to arduino as well but I need the pi zero to be able to run a specific raspbian software on its own and have its own controls... I believe assembling this game controller is a similar process to building a handheld gaming console BUT I don't want the pi zero to run a gaming software, I'm going to put a unique raspbian software on it... Also, would need both(if you use the Pi Pico and Pi Zero) to be able to connect to a computer via a the SAME USB and/or USB-C to play games, operate as a mouse, and I need the pi zero and it controls to have specific functiona...

Hi there, I have an ESP32 with a simple arduino code that exposes two characteristics, one push notification and one read/write characteristic via BLE, see attached. I need a React native app (Visual studio code with Expo) that via a button press scans for this device and connects to it. Once connected, it should display the value notified from characteristic 1 in a simple text and continously update it when a new value is received. It also needs a button that writes '0' (zero) back to the read / write characteristic. Thanks! Marc

I need some help with CCtalk and to create an interface for a coinchanger. This is a project that is very close to what I want to do: It does not have to be arduino. ESP32 is an aternative. PIC another. I have some Arduino skills and are able to create the setup in Sweden. Some of the development will be thru TeamViewer. You need to have a CCtalk host to be able to verify your work. I will copy your work and apply it to a Comestero coinchanger. The task is to have 4 buttons. * 10 SEK * 20 SEK * 50 SEK * 100 SEK (option is 5 buttons and 200 SEK) When a button is pressed the coin value is sent to the Comestero coinchanger and 20SEK = 2 tokens from the coinchanger. The buttons will then be replaced

I have a custom GPS tracker with a 2g GSM module from ublox, unfortunately the 2G GSM signal is always low with any antenna I use, the signal strength is always low 20%, on very rare occasions it reaches 40%, I have tried about 10 antennas but it never exceeded 20% I also soldered the antenna directly on the GSM module, tried various sim cards, I even went under the repeater, but it is always 20% -40%, the mobile phone instead has 100% signal, the test was done on 10 trackers, is it possible that some component is missing on the PCB?
