I have a couple of holiday homes with an airco (LG s12et) and a NILAN compact P heat pump. Both systems can hear or cool the house but at this moment a lot of times the systems are working against each other because the temperature that is wished, is not synchronising. Maybe this can be done with modbus or something. The project is: -selecting the right hardware -maybe write some programming language -With the right instructions I can connect the hardware myself easily. I have attached the NILAN specifications. The LG airco specifics are easy to find online.
Hi, We want to make a heart rate monitor for horses , this project should require experience in electronics and pcbs where the the freelance is expected to show in his proposal what ICs he will work with, mentioning the exact model, and what time of microcontroller or microprocessor he will use, Thanks
There’s some things I didn’t specify in this drawing. The esp8266 has 15 pins on both sides, The lcd adapter has 4 pins to the left and 16 pins at the bottom. Then I’ll need another 16 pin vertical female header for the lcd screen (pin 1 from the adapter would need a trace going to pin 1 on the lcd adapter board, 2 with 2, etc.) As for the components I’ll just need holes so I can solder them. I’ll just need it printed as for which hole is which. [Removed by Freelancer.com Admin]
This project is based on the save power concept, in bathrooms, we turn on lights and forget to turn them off which leads to power wastage .to tackle this problem we need to set the delay to lights to means after 7 -10 min of turning on the light it will automatically turn off, need to design a circuit to solve this problem
Hi. I need to get a Raspberry device to set it up for my car. Can you supply me with the device and its setting. It's the best thing for me. I give you the link below where everything is well documented. Apparently it's easy but I'm useless in IT. Thanks for your feedback. The person need to be in London for delivery nd setting.

Build a new PlatformIO/Arduino project in C++ using the Seed XIAO sensor platform. Using the available public libraries create a bluetooth peripheral for the PDM microphone, pair the microphone and stream the microphone audio to the host. Using the available public libraries create a bluetooth peripheral for a MS5837 pressure sensor pair and and publish the calibrated pressure and temperature to the host on an interval set by a pushed value from the host. Detect when the XIAO has been moved using the IMU and wake the core from deep sleep on movement. Detect when the XIAO has has not moved for a time and put the XIAO to sleep.

I am currently developing a battery powered DC variable power supply and I need a PCB created to control it. I would need it to have a buck boost circuit that could do 0vdc-60vdc @5amps as well have a current limiting feature for testing equipment, etc. & perhaps digipots to control the output voltage and current limiting digitally through the menu. I also will be using a TFT LCD to display a menu & to show voltages & current draw, so using an STM32 to drive & control all the logic would be preferable. Im not sure which batteries would be best to use in this so achieve the desired power outputs that I want so perhaps you may have some suggestions for batteries but for whichever batteries it would need a BMS and all protections as well with a USB C recharging circuit for re...
I would need Simple circuit design that does the following 2 tasks for a 5V arduino pro mini 1. Power the Arduino (5V) from a car Battery (12-16V) including protection circuit. The Arduino should keep Power for about 5 seconds after the Battery power is switched off 2. Take a 12-16 V square wave and reduce it to a 5V Square wave via a opto coupler so it can be used with a digital input I don't need a PCB Layout

I need a code for arduino and the language is c++ for this project: Our project is an automated pillbox: It has arduino uno wifi, LCD I2C, keypad 4*4, buzzer (alarm), 2 IR sensors, 2 micro servo motors. 1- the patient will set the pillbox he will enter date/time. 2- he will choose number of medications (1 or 2). 3- he will enter the time and number of pills for each medication. 4- when it’s time to take medication 1 alarm will go on until the patient press the button on the keypad. 5- the door of medication 1 will open using micro servo motor. 6- there is IR sensor inside the compartment of medication 1 to sense the medication has moved or not. 7- the patient has to conform taking the medication if yes number of pills for medication 1 will reduce by 1 and upload to the cloud. 8- aft...
Hi, We need to design and develop IoT devices that must have following features: 1. Humidity Measurement 2. Temperature Measurement 3. Accurate Location using GPS Further details will be shared with selected freelancers only. PLEASE BID IF YOU HAVE DESIGN AND DEVELOP SIMILAR PRODUCTS BEFORE. Thanks
I need help creating a custom DIY bark repellent device. It can be based on Arduino, Raspberry or pure electronics - Raspberry and Arduino being the best as they can be easily updated or programmed. Anything I can find on the market are small toys without the much required power. It has to use larger loudspeakers - not the tiny kind you see in any bark repellent It has to allow change of frequency (as in adjusting for a specific dog/animal). From what I understood it has to emit ultrasonics around 20kHz-25Khz (in case of dogs) so it is not a such complicated device but I need someone to think about all these aspects and compatibility of the electronic pieces. I have very good coding skills and some basic electronics knowledge so I will be able to provide feedback and help with anything...
I’m looking for an experience individual who have worked with drive control algorithms e.g PI,MPC,HC. I am implementing model predictive current control for dynamics performance of SPMSM. In simulation the model is working very well and system show excellent closed loop performance. I want to implement it on hardware(Tms320f28335), if someone has experience of implementing MPC FOR motor drive then feel free to message me here for further discussion.

Hi Everyone, I’m looking for an experienced ESP32 SW engineer to create a wireless file transfer tool. I have an ESP32 connected to a Teensy 4.1 trough SPI and Serial port bus and I need to transfer some files stored on the Teensy SDcard over Wi-Fi. Each file is around 100MB so SPI bus is the only option and a fast transfer protocol is needed. The code to be written is divided in two sections. 1. Code loaded on the ESP32 to include a small webserver where the user can open a browser and look at the files available on the SDcard and select the one to download. The ESP32 will request to the Teensy to transfer the files (ESP is the SPI Master) 2. Code loaded in the Teensy 4.1 will negotiate with the ESP32 the access to the SDcard. The Teensy will also need to tell the ESP if is curr...
Siren for Police - Programmable Hello we have here a SDF104H from Axixtech Juluen in Taiwan, the problem is this siren have a controller with RJ45 with different buttons and more. Than we have a HRT (Horn Ring Transfer) Signal with PLUS and MINUS, when we give here a PLUS than go only on a HORN SOUND by the Loudspeaker in the Lightbar. We need here the Sound from the Sirenen Button. Which solutions can you offer to change Firmware that the SIGNAL is SIREN ON/OFF? How can we read the Firmware or change this Signal ?
Hello, we need a complete PCB design and component selection. for a camera battery charger. there will be 3 Batteries of Sony camera see image for details. Device should have display to show charging percentage of each battery. we need a professional person for this project.
I have indoor grow tent, with multiple citrus trees, It runs an exhaust fan, 4 air moving fans, 4 lights, 2 heating pads, and an irrigation pump, I currently run most of the items off of a wifi power bar (geeni surge 6) and the exhaust fan runs via its own controller with temp and humidity settings. The irrigation pump is supposed to run off of a wifi based application (the app no longer exists) I am looking into the idea of getting a raspberry pie and running the entire system off of that with some programming. I would have to regulate on/0ff times for lights and exhaust fan and also integrate a run cycle for the irrigation pump. If anyone has any insight into this tye of system please lets start a conversation
