I wanna control 4 (12v) dc motors with the help of an arduino ad joystich in such away so that when we forward the joystich the 2 forward motors became active and as much we tilt our joytick toward right . the voltage in right motor fade down and our project car could move towards right same wjth the left one. And when we move our joystick backward our 2 back motors became active and same concept here also of right and left .
Hi, We are looking for technical writers to write on different projects designed using Arduino, Raspberry Pi, PIC, Atmel etc. Thanks.
Hi, I am building a project using SAMD21 J17 Microcontroller, but i am unable to make it work in Arduino ide I have previously been successful in modifying the standard Arduino zero bootloader(samd21g18) into a custom bootloader for SAMD21 J18 , but am not able to do the same for J17.
Please see this video skip to 29 second .. i want the robot to do something like this
Hello i am a Computer Engineering Student, and i am currently doing a project in Computer Architecture about an Attendence System using Arduino uno but i just cant get it to work. The parts that i need for this to work are : RFID reader, Breadboard, 2 LED lights one red and one green, a buzzer to make a sound, and a MicroServo99 motor, And an Arduino Uno and i have all of these and i figured out how to connect these all together ( i also added a picture so you can see how it looks ). What i need to do is that Every member that i add using a website (i can do the website myself) gets acces to make the green light shine the buzzer make a sound and the motor to rotate, and the time the name and id of the person to be registered in a MySQL database, wich is going to be connected ...
I am trying to make an arduino project that has 2 temperature sensors connected to two different LED strips(WS2812B). I want the lights to change depending on the temperature of each person. Colors would be blue for cold, orange for normal, and red for hot. I would like the motion on the lights to be a color wipe. I would also like to connect two small motors to rotate objects with a motion sensor.
I need help in implementing a use case with LoRa SX1278 operating at 433MHz. I want to send a signal to another LoRa/RF receiver when an even happens WITHOUT using any microcontroller/Arduino. For the event, there is already a sensor which works like a relay - normally open, normally close and neutral. I want to send a signal, whenever neutral gets connected to NO or NC. The receiver can be LoRa but I would prefer a normal 433 MHz receiver. No specific message text is required for communication, only the receiver should be able to differentiate with two type of singal for NO and NC.
We need a 24vdc in to 7vdc out - buck converter @ approximately 1.5amp to power an Arduino Mega / DUE. The onboard regulator gets hot if driven above 8vdc, so I want to have a dedicated 7vdc PSU that doesn't get hot like a traditional linear LM7812 does. I've used AL8805's in the past and even LM2596's, so am open to ideas as long as they're not end of life components which will be hard to source later. Just need a schematic and formulas for 24vdc in - 7vdc out. Milestones will be paid: 1. 50% on supply of the circuit details 2. 50% on completion of testing the circuit (will need 3 days to get parts and build it)
I am working on a project. In this project - we need to rotate a 9V or less DC motor for 10seconds at particular speed and then stop for 30seconds. Again rotate in the same direction for 10 seconds. - This cycle must be continues till there is power supply. - For now speed control can be a knob/Potentiometer. - There must be ON and OFF switch - The circuit must...need - a circuit design - Programming for the micro controller - recommended parts to buy including motor, battery, and other necessary parts - BOM - purchase links for the parts listed in BOM. (Only local Indian products. No Chinese website links like alibaba, alisource etc.) - Price estimation for the project including all raw materials for 100pcs. The application is for real world use. So Arduino is not preferable and...
Hi, network pros and gurus. I am trying to set up a development environment with my main pc(linux Ubuntu 20.04, and Windows WSL2), several raspi/jetson/arduino boards on a local network first; I also want some NAT of my router to be allowed to access this. I got Nginx working for my apps, but I'd like a script to replicate this once I get to staging servers. For xterms and screen issues on both machines, I believe I got a solution from this link. Plz check that for your reference my budget: usd 30 for scripts and setup If it holds up for the next month, I will provide a bonus.

...project "for free" (without spending one of your bids). Please wait *patiently* for up to 48 hours for me to invite you because I do *not* have a bot; I would need to manually invite you to bid. ✻ THE PROJECT ✻ You do *not* need an ESP32 (which is similar to Arduino). You will help me build a consumer IoT (Internet of Things) product using MicroPython on the ESP32. MicroPython is a subset of Python used to program microcontrollers. ESP32 is a microcontroller (similar to Arduino) but ESP32 is generally better and more powerful than Arduino. ✻ DAILY PAYMENT ✻ I will pay you each day for every hour you work with me. That is probably *very* beneficial for you. Obviously this will almost completely eliminate the risk that you will be unpaid for your work...

To use the Tesla battery pack Ingenix has developed a module to control (turn the battery and the charger on) and monitor the pack (such as voltage/state of charge). The operation of the battery is controlled through the Ingenix module on the canbus. Ingenix provides the dbc files. I need someone to provide a program a simple arduino can shield with a small led display to control and monitor the operation of the battery pack. For details of the Ingenix module see:
...Roulette. I already developed the physical Roulette table and I have loadcells under each of the betting options (0 straight up, 0-1 split, 0-2 split, 0-3 split, 0-1-2 Street, 0-1-2-3 Corner… and Red, Black, 1st dozen, 2nd dozen, 3rd dozen, 1st column…). Those loadcells report weights placed on the physical table to Arduino IDE (everything is developed including the code that reports the weights to Arduino IDE, e.g. if I place a weight on any of the loadcells, it gets reported to Arduino IDE) Details of the project: - When you put weights on any of the loadcells those weights are reported in real time (ongoing sessions) - We need to take these total weights and transform them into casino chips - So every reported total weight in grams needs to be...

...two (ultimately wireless) orientation-type sensors placed on specific parts of the body, 3D orientation readings taken and synced together during a swing, and visual and mathematical comparisons of the orientations at various points of a swing (as rotated around to different angles on a 2D display). A properly operating software application is far more important first, and I have a couple of (Arduino-type?) hardware units put together by the most recent contractor that can hopefully be used. I have attached front and back images of one of the sensors for reference. While powered by USB cable, its data is sent wirelessly by Bluetooth, which is linked to my desktop. If it is important to know what any given components are and that cannot be made out on the images, please let me kn...

Our company has a machine to measure the loft and lie angle of golf clubs, this is done by measuring different resistance values and performing a five points calibration to convert it to angles. The problem is we are not saving the calibration data into EEPROM correctly therefore the calibration data resets when power is cut off.

I would like to get the TVout library to work for STM32F030. (with the Arduino IDE, preferably using the stm32duino boards manager ) I tried converting the ATMEGA library to STM but I wasn't able to make any progress (I'm a mechanical engineer, updating that lib was well beyond my capabilities) I also tried one from "" but was not able to get it to work/ it comes up with warnings/errors (some listed below).
