I need an Arduino Code which allows for four relays to run a single sequence entirely when a button is pushed. Including button.h sounds like it will work. This code does not work, but "Front" refers to the front doorbell. "Back" refers to the back doorbell. The four relays are set to pins 4, 5, 6 and 7. int Front = 2; int Back = 3; int RelayControl1 = 4; int RelayControl2 = 5; int RelayControl3 = 6; int RelayControl4 = 7; void setup() { (9600); pinMode(Front, INPUT); pinMode(Back, INPUT); pinMode(RelayControl1, OUTPUT); pinMode(RelayControl2, OUTPUT); pinMode(RelayControl3, OUTPUT); pinMode(RelayControl4, OUTPUT); } void loop() { if (Front == HIGH) digitalWrite(RelayControl1,HIGH);// NO1 and COM1 Connected (LE...

Previous engineer did a great job but sadly let us down on fixing bugs at the end. The project is a RS232 controlled timer module with LED matrix. Firmware is written in Arduino. PC control software is written in Python. PC software polls and sends commands to multiple boards connected to RS232 ports. Both pieces of code run very nicely together and we are using it daily in our business but we now want to iron out the last few bugs from the code. For example, one of the bugs is a Python crash during the connected PCB search routine if more than one type of RS232 adapter is plugged in. The others are more or less as trivial. Once the first bug is fixed satisfactorily I'm going to post each successive bug as a standalone extra milestone with a new payment attached to it.

I have a arduino sketch. Led blink on millis.(no delay) Led on for 5 seconds and off for 50 seconds. I attached to arduino button. Now I want when I'm anytime short press button , led on for same 5 seconds. But when I'm long press button , arduino need store how many seconds is was pressed and change led on time to that value

I would like to make a communication system using Arduino or Raspberry pi that allows to people to communicate with each other. The one is on the "base" where the communication center is and the other one can be to maximum 100meters away and holding only a microphone and a speaker. Not a wireless communication. There is communication line (wire) throughout the whole distance.

I'd like an arduino to turn on and off a set of up to 8 relays independently and in succession. The user can set the amount of time in minutes and seconds that each relay needs to turn on and off for. The arduino has an LCD screen that displays up to 9 pages. the user can scroll through each page. The first page has a summary of what relay is active, the relay's time on, and its time off. There is also the ability to turn on or off ALL the relays The remaining pages (one page per relay) allow the user to see and set the amount of time the relay needs to turn on, and off. Each relay page will have: Relay Name (Alpha numeric field); On time (Minutes: Seconds); Off time (Minutes: Seconds); Current status (On or Off) If all the ON and OFF times are the same, each relay...

By using an arduino nano 2 trigger sensors call them trigger 1 and trigger 2 needs to be able to count. Trigger 1 then 2 counts on up and trigger 2 then 1 counts on down. When it reaches a curtain limit it needs to switch on the light and when there is more than the limit it should flash the light. As soon as the limit is less the light goes off. I need to be able to set the limit in the programming. I need someone to be able to program this small project for me. I have all the hardware and just need someone to program.

Develop an automatic tracking system which will keep a camera aligned with the sun at a 0 degree angle such that the sun always stays in the middle of the camera frame. The system will rotate the camera up and own/left and right according to the sun’s position using stepper motors controlled by an Arduino/raspberry pi to align with the solar position. A rough diagram is attached Note: The end product we require is the software(code) that you'll use to implement the project so that we can replicate it ourselves.

Please have a look at this video from the 0:15 time. You will see this yellow cylinder holding a train and spinning 360 degrees to discharge the train. So, I need to improve so it is always aligned or add an alignment system so it is always perfectly aligned waiting for the train (see time 1:33 of the issue). I am going to give you the original code, perfectly working, but i need to add the rotary encoder or another system you recommend me to add to get it to work. To sum up, the project is: modify my existing device so I can get a position feedback and self align the wheel. Please bare in mind this is a hobbyist project and it is not intended for commercial application; so my budget is quite low.

I have a lego train that approach to a lift. 1. There is IR sensor, detecting when a train is on the platform 2. the motor will get activated and the lift will go up, until a limit switch is hit, stopping the lift. 3. the train get off the platform, the lift remains up 4. the train is back onto the platform, the lift goes down, the motor gets stopped by a bottom limit switch 5. the train gets off the platform, the lift remains down, waiting for another train to come back up 6. the cycle repeats itself again.

I have what I THINK will be a simple project... I want to create a WiFi-enabled controller for a process I’m currently doing semi-manually. It involves several things, but the more complicated stuff/code has (I think?) already been done... I currently have an Arduino that is operating a turn table (via a DC motor), triggered by a load sensor (ie, a kitchen scale), and guided by hall sensors (ie, tells it where to start and stop when initiated). All of that code has been written and the process is functional and operational. It just needs to be translated to both a physical display screen, and into a WiFi module. I’m thinking about using the Blynk app as the base? It seems to have all the capabilities I need but every time I try to start making it I get lost!!! ...

Hello, I would like to have a board with 7 Segments (or maybe you know something else’s). It should be possible to add a present date (by eight 7 segments) and there should be two 7 segments for year, two 7 segments for month am two 7 segments for days. These should show the past time still the present date. I want to produce a prototype by pcbway.com. The segments should be white, there should be a on/off button. The power should be batterie. It should be possible to dim the brightness. And it should be possible to add the present date by buttons on the backside. So I need the Gerber file, BOM file, and Pick and Place file and the code. I think we need an RTC to make sure the time will count when the device is off. Greetings from Germany Johannes Schild

Hello, For a personal project I need someone to develop some Arduino demo code with the ESP32. The peripherals to drive are: SPI ST7789 display, I2C/SPI RC522 RFID, SPI SD card, UART GPS, Buttons, Relays, ADC moisture sensor, Audio/I2S MAX98357. All the Arduino libs that drives these peripherals are already available on the internet. The scenario is just a demo code that shows that the ESP32 is correctly connected and can communicate with the peripherals. The ESP32 is connected to the PCA9698 IO expander. Tasks: A)Do schematics with breadboard B)Develop Arduino demo code C)transpose the schematics into Altium or Kicad schematics ready to be routed The complete specification of the work will be transmited later to motivated candidates. Regards, Michel

Update a alert system for a child's car seat that was working until 12/30/20

What is the deliverable? A firmware file that will work on an Arduino board and accompanying windows file if needed. Help with physically creating the prototype on our end, through the way of schematics and/or video call. What needs to be done? We need to turn on a LED if a certain service is running on a windows computer through an RF module (nRF24L01). We will need to use a 1 x USB module that will connect to the computer and monitor the status of said service, if found active, that will send a signal to a GPIO RF module that will trigger the LEDs on a different board. How many services do we need to monitor? There are 2 services that can either be in an on or off state. That means Service A can either be running or stopped and the same with Service B. We can use a different m...
