write source or help trouble shoot using debugging tools our existing code. C (Arduino IDE) but prefer to use Atmel Studio Using ATmega328 or ATMega168P QFP CPU Monitor 5 I/O pins - to determine if a switch contact is open or closed Closed is Good, open is alarm condition Also use A/D to drive an LM84T temperature sensor and measure once per minute Alarm condition if temperature is over 75C once per 5 minutes - use serial lines to operate and send a message using HopeRF RFM95 LORA radio module. (this is a 'status ok' message) We have library for this radio module When alarm conditions occur (contact open or temperature >75C) alarm message sent. Message payload is 6bits - we have this defined. Device sends messages only 1650mAH battery - target 5 years life We have this...

Im currently working on a simple project creating a easy interactive touchscreen user interface consisting of menu cycling and press functions that control connected devices.

Build the Hardware and Software for an Arduino based project as a proof of concept. You must be able to receive hardware at your location, test it including videos showing the product working, then ship the device with build instructions to us in Australia.

I want to control my stove oven with two stepper motors, but my Arduino programming knowledge is only at the beginner level so I hope somebody made an similar project or can program it. Let me try to describe the logic of the program. 1. If I push the K1 Pin on the display, the controller should start an reference drive to setup its end positions. (Status: Reference) 2. Then the stepper motors has to drive to an predefined position (Status: Fire Up) 3. If the exhaust temperature rises over an temperature value for an predefined time, the controller should start working (Status: Normal) 4. Both stepper controllers must work in parallel 5. If the temperature or oxygen values are out of range, the stepper motor should control it 6. If the temperature or oxygen are in range, the stepp...

Hello! I just found this site and decided to try. I'm trying to find a Arduino MIDI specialist. I would need help for writing Arduino MIDI keyboard controller code. I'm not able to do this myself, it's too complicated for me. Is there anyone who could solve my problem? Here's the project: I'm trying to figure out how I could do a MIDI keyboard with velocity sensitivity with Arduino. I understand the idea behind the velocity sensitivity keyboard, but I'm not able to code it myself. I know already how to make a ACTIVE MATRIX based velocity sensitivity BUT I would like to know how to do a PASSIVE one which doesn't use rows and columns, only common ground method (just like in the 61 midi keyboard code). I'm sending you a ready ...

I have implemented a simple websocket echo server and a corresponding client that runs on separate esp32s3’s and communicate via wifi and it works. However the performance is very poor (~ 500ms for a roundtrip) so what I need is a optimization giving ~50ms roundtrip times. I have also implemented a python client and tested it against the esp32 server with good results (1000 roundtrips): Number of echos over 50 millies: 999 Number of echos over 75 millies: 40 Number of echos over 100 millies: 29 Number of echos over 150 millies: 13 Number of echos over 200 millies: 8 Number of echos over 250 millies: 8 Number of echos over 300 millies: 5 And I need the same performance with a client implemented in C/ESP-IDF. I’m using ESP-IDF 5.0.1 and the sources are attached.

Hi. I have a few projects I need help with. Functions listed below: Script that can do the following: 1) 2d linear stage with solenoid; needs 3 programmed positions + homing, ability to engage/disengage solenoid at each position. 2) second 2d stage with Pi HD camera; essentially moving camera along the 2d stage positions and trigging camera to capturing images. There also needs to be built in function to rotate two separate steppers to specific locations in-between each image scan set. 3) two thermo electric controllers to control temperature, no tuning needed. 4) likely a separate project, but need someone for computer vision to sitch images together, and some post processing, if we move forward we can talk more about this one.

...HX711 ADC amplifier (datasheet attached). It will certainly need a Bluetooth chip, ATBTLC1000A, (datasheet attached) and a chip antenna, ANT1005LL14R2400A, (datasheet attached). In addition I need added resistors and capacitors to decouple the pins that I will be using, though I am unsure about the value of resistance and capacitance needed so please use your expertise for that. I will be using the I2C pins for connection with the output of the HX711. The PCB will be used for measuring weight and sending it to a phone using Bluetooth LE. It needs 2 pads to be connected to the positive and negative ends of the 3V battery. In addition it needs 4 pads to be connected to the off board strain gauges (2 strange gauges). The two strain gauges and two resistors (350 ohm) will be used to...

Hi, My hardware: ESP32 with an I2S microphone ICS-43434 connected. I have a firmware1 for ESP32 which records sound in very bad quality. So the microphone is not compatible with the driver in this firmware. I have another firmware2 which records sound from the same microphone in very good quality. So this I2S driver works perfect from firmware2. I need to get firmware1 running with good sound quality recording. And hope you can do that for me. Here is firmware1: And firmware2 (with good sound): I think the problematic file in firmware one is this:

The thermometer is is a Fine Offset WH2/FT007TH. In order to offload the ESP32 it might be better to use a integrated receiver like RFM69 or CC1101 instead of RXB6 simple superheterodyne receiver. However if the ESP32-C3 has enough power for all tasks, the RXB6 will be fine too. The wireless protocol is documented here: Data needed from sensor: -Sensor ID (1-8) -Temperature in celcius with decimal -Humidity Defined variables: -SSID -Password -HTTP_POST_URL -API_KEY When packet with valid CRC is received: -Make HTTPS POST: key=test&ch=channel&tmp=temperature&hum=humidity -Implement timeout for HTTPS POST (so it will not hang if internet is offline) -Print received data to terminal with result for HTTP POST (OK/ERROR) Code
