I am trying to control two independent robots simultaneously using two Arduino Mega with USB host shield and xbox 360 wireless controllers (2.4 Ghz dongle). But I sometimes face the issue where the xbox controller disconnects and connects to the wrong host shield arduino mega. Is there any way...

Hello, I am using the Arduino Servo library to actuate two BLDC motors and ADK USB Host Shield to control them using a USB dongle controller (XBOX). But I am facing issues particularly in calibrating the BLDCs and lose the host shield. The most probable problem I could think of is there are some...

Hello, Sorry 1) if this is wrong place 2) Dumb question. I am working on smart irrigation project, I have Arduino connected with 4 sensors and 1 actuator, Arduino collect data and send to ESP32 using Reyax RYLR896 Lora Module connected to it. I keep all PCBs in one waterproof box, but this...

Hello everyone, I have next to no knowledge of electrical eng or circuitry and am having some trouble with my homebuilt arcade. The essence of my problem is that I want to wire both the computer and monitor to the same rocker switch. The monitor turns on via a button press that completes a...

So I have a switch connected via two wires to a two pin plug which is supposed to go in a two pin socket. One pin of the socket goes to 5V and the other goes to a digital I/O in the Arduino + GND (via 10K). When the switch is pressed and the digital arduino pin goes high, stuff is supposed to...

This project is a temperature monitoring and fan control system. It uses an LM35 temperature sensor to measure the ambient temperature, and an Arduino microcontroller to read the sensor data and control three 12V fans. The system has three LEDs that light up in different colors depending on the...

Hi All, I am a very new user to Arduino Programming but have been developing Windows programs for more than a decade. Need help in installing, setting up and Using the VS-Code utility to code, program and build the Arduino Sketches using Arduino Programming Language code in VS-Code.

I'm using 4 x 50kg load cells and an Arduino Uno R3 for an interactive music project where a dancer will perform on top of a stage with each sensor under the corners of a board 'stage'. I need to monitor each cell individually as these values will be sent to Max/MSP (an object-based coding...

i need help in my end year project. i want to create a smart parking using InfraRed Sensors and add some features like online reservation and payment Any help or Suggestions

note : 5 channel flame sensor is used which is mounted on the end effector of the arm,and the robotic arm scan does 180 degree scanning...So experts you are all in here.. hey listen m also using PCA9685 Servo motor driver to control the robotic arm ,,,i just only need the help in following /...

Hello, I am building a cubesat that will be launched aboard a rocket, inside a locker in the pressurized crew capsule. One of the onboard experiments calls for radiation level sensing. I see that the Pocket Geiger Type 5 (SEN-14209) needs to remain still, otherwise it will give false readings...

Hello all, hope you're doing well. I have a peltier (12 V and 7 Amps) and I want to control its temperature using Arduino. I was using the N channel dual MOSFET module and it worked just fine except that it does not switch polarities. I have read about H bridges but still not sure and it is...

Hello Here I am again with the car, but now there is no problem with control :). I just added an ultrasonic sensor to the front of the car, with the fact that if the distance is less than 20 cm, it should stop. When the car is running, it works once or twice, but on the third attempt, the car...

Now I detect motion with my Arduino Nano and 3pin motion detector: When detector triggers, I need to send signal (distance at least 5km) to another Arduino Nano and catch it. As far as I understand, 433Mhz is the optimal frequency for this. Please suggest me what should I use? Which circuit...

Dear all, this hobby project I setup is using an encoder to make the stick to be 90 degress which is at 1500 steps (0 degrees=perfectly horizontal using PID control). My encoder counter code is obtained from video here and I have tested it which works perfectly well. Since this encoder is 1200...

I have a project where I need to make a person counter for a room. I have two PIR sensors on either side of the door, depending on which one gets set off first, it means that a person is entering or leaving. The code for this part works well enough that the counter is incremented when someone...

Hey there, I have a several enquiries to ask regarding my Arduino Project But before that, I would like to explain what my project is about: As you can see from the images, I plan to make an automated timer system where System 2 detects the tray placed on it through a switch, in which if the...

Hello, so as the title says I am currently making a RC car as a little project while I try to learn Arduino more. The car is a Bluetooth controlled car controlled using a HC-06 Bluetooth Module. My main issue currently is that I have made the design minus a schematic, made the code for the...

Good evening all, Background: I am final year Electrical & Electronic engineering student currently in the process of completing my undergraduate thesis. The thesis topic consists of making a low-cost, non-intrusive, battery powered electronic device that is small enough to fit in the punt (the...

I have a conductivity kit from Atlas Scientific, but the ezo conductivity module is missing. I just connected the sensor probe to pin A0 on the Arduino Uno with the analogRead command in the source code. However, I'm still confused about the sensor output. Can I convert sensor output to...
