Need to create a sketch for Arduino IDE for Atmega328 and 2 12segment level indicator (stereo)

i want to make a GPS tracker PCB that will connect to my server using either TCP or MQTT. To achieve this, I'm considering using a main chip like the ESP8266, ESP32, or ATmega328. Additionally, I'll need two other chips or modules: one for GNSS/GPS and another for the SIM data connection. My goal is to achieve accuracy comparable to the Chinese GPS trackers available on AliExpress. I've looked into Quectel and Simcom, but there are numerous options available,i want some combination that offer performance and cost-effectiveness. you can suggest different chips if u think that they should be used. pcb will have some other basic sensors but thats easiest part --only bid if u have experience with gps and gprs/lte

Dear sir or madam. I would need help with programming. I already have an arduino program for my design (pcb with atmega328 ic) - it is about temperature regulation and also I use 1.3inch lcd display with ST7789 board for showing data. The problem is that if the screen freezes, it doesn’t refresh automatically and stays freezed (I need to unplug and plug again the power). I would probably need separate program for the screen, which would recognize when the screen freezes and then refresh it. Or do you maybe know any other solution? I hope that someone could help me. Have a nice day! Gašper Vidmar

Thinking of a small project to first test on an Arduino and then move to a atmega328 or other chip that will need to sense a small micro switch that will be Normally open. . If micro switch shows closed continuously for 120 seconds then chirp sounder until the switch is made to be open again OR a momentary switch has been tripped manually which will reset the timer. Will also need help with being able to move this over to the chip instead of the Arduino and this bid will need to cover the process of what all is needed to make that happen.

The system I des...system I designed is called "FPV Combat", imagine to play a dogfight simulation game but in real life with real RC (radio Controlled) models with "real" danger and a great amount of adrenaline! Take a look at this demo video: This is designed to simulate fight with infrared system on RC models such as planes, drones cars... I'm moving this project from ATmega328 to ESP32. It was originally designed to work with analog FPV system I need somebody that can help me migrating the project to the newer hw and implement MSP communication (canvas mode) for the different digital FPV systems available now in the market (DJI, Walksnail and HDzero). Additional features might be needed now or in the future but we can discuss about it later on.

Hi Sardar Hasnain A Brother please I have a question I have an electronic device and I use a Pic microcontroller (pic18F27K40) I worked with a programmer, but he specialized in the Atmega328 controller, and he told me that changing the controller to Atmega328 is easy and it will work with the rest of the current hardware without any problems I worked with him because the previous code was wrong and I want him to do the code again What do you think, dear brother?what he said

Hi. I need someone to get some Arduino code for the ATMEGA328 code to run on an ATTINY10 under Microchip Studio. Thanks.

Description: stm32(transmitter)-->nRF24-->stm32(receiver)-->sim900-->Internet * Transmitter is in sleep mode and every hour wakes up and receives temperature from BME680 (The embedded RTC on stm32g071rb has to be used it) *Then, it sends via nRF24 the temperature and the time (in form Day/Month/Year/Hour/Minute) to the receiver and returns in sleep mode *The receiver is in sleep mode and when a package from the transmitter is received, it wakes up to receive it and then it sends the received temperature and time via sim900 on a website (.php) Deliverables: *2 codes (1 for transmitter and 1 for receiver) *Schematic for the modules * Verification with measurements (power consumption) that the sleep mode works Deadline: There isn’t any deadline

Small project to program an Arduino Uno R3 to have to inputs. 1. A dry contact that is NC 2. A Ultrasonic Module HC-SR04 Distance Sensor or your suggestion for another component to do same job for proximity sensing. Upon both 1,2 being met then send voltage or signal to close relay. When either 1 or 2 are no longer true...drop voltage or signal to relay OR optionally wait “X” seconds then drop voltage or signal to relay. Relay has control of 5v dc. To let me know that you have read this far down into tue instructions please add the words “done it” at the end of your first sentence in the reply to me. Will need Fritzing design and documentation for wiring etc. Eventually will be replacing the Arduino for a atmega328 chip. So will need to rehire ...

Develop transmitter and receiver circuit and pcbs for 900MHz radio that takes extremely small amount of current to preserve battery life. Must be designed using discrete components, and not using SIM900 chips. The radio will communicate digital data bits at 1000 to 10000 bits per second, using half duplex. The radio should be able to communicate at a distance of 500 meters or more. The transmitter/Receiver circuit must be developed with USA Fcc requirement in mind. Must be able to pass Fcc tests. Must have in-depth understanding and experience with wireless and antenna technology we need to incorporate this rx/tx radio in our cpu boards. so you will need to build sample demo units, perform testing and give us feedback on the results, send the samples to usa for our own testin...

RS485 with atmega328 with IO ports needs to be designed.

I have tried to add as many details as required to understand the scope but I can be available if more information is required. The Background: I have a product that uses HM10 as a Bluetooth communication device. It sends received commands to atmega328 which in turn turns a light on or off (and does a few other things based on commands). Commands are very simple we have added Arodino code to run commands and achieve the desired functionality. Mobile apps: We have two native mobile applications. One for Android and another for iOS. Both worked fine until recently. The right hardware: We were using HM10 which was working fine with both iOS and Android. When you run the AT+VERSION command on this one, you get a response:"MLT-BT05-V4.45". This hardware has the attached me...

The library should support USART with for example 9600 baud on one pin (interrupt for receiving and sending with timer) I tried to adapt for supporting one-pin mode, but it doesn't work. Maybe because of changing of pins out and in mode. It is needed for a study.
