Hello everyone! I’m going on an International flight soon and I’m currently working on a project that involves the Arduino Uno and other components such as LED’s, IR sensors, 9V batteries, a BT module and jumper wires. I don’t know if this is the correct subreddit to post on but, how do I go about carrying it? I don’t want anything to get confiscated and I have minimal experience with any of this. Any advice/help would be greatly appreciated. submitted by /u/metro_17 [visit reddit] [comments ..read more

Uno R4 Bluetooth Module Rx Tx not sending data to Serial

8h ago
I'm building a small car project using geared DC motors to drive and a servo to turn. It is controlled via Classic Bluetooth and an Android app. Functionally it works perfectly using SoftSerial (A4 + A5 pins). However, I read that the SoftSerial library can interfere with the Servo.h library so I am trying to get rid of the SoftSerial and use the onboard RX TX pins. I have stripped the car down to the most basic components and cannot get the onboard TX and Rx pins to receive or write data to Serial. What I want to do: Turn on the PIN13 onboard LED using a 1 for ON and 0 for OFF using a Bl ..read more

GSM SIM900A Problem

Bought this GSM Sim900a from China through online cause the retail stores here sell it for twice as the price I paid for. Anyways, when I plugged it into my Arduino Board, both the LEDs are blinking, from looking it up on the internet it doesn't have enough power? Things I did: - Used a breadboard power supply - Tried with a different board - Swapped the SIM with different ones It just doesn't seem to work, all I want for it is to send a message through SMS and that doesn't even work. Please help I'll do any of your suggestions (not taking electronics or computer engineering courses, tink ..read more

[noob] - new nano not showing as a serial device in linux

I have just bought a starter kit with a Arduino nano. When I plug the usb into my linux box the nano itself has one solid light and one blinking light. on the linux side there is no evidence that the usb/serial device is connected. if I list active serial devices the only one is /dev/ttyS0 (and that shows up in the IDE). If run # dmesg -c after a unplug/replug nothing is shown. my user is part of dialout group is there some nano driver that I need to install or something? Update: bad or power only cable was prevented connection. I now have a new problem, the ttyUSB0 device is only present for ..read more

Playing buzzer music with IR remote. Why doesn't the music play for the second time?
Reddit » Arduino

What I'm trying to do I wired up buzzer and IR receiver. I'm trying to play music with buzzer using IR remote. I intend to make the project so that if I press button 0, playtestSong() gets called to play some music on the buzzer if I press button 1, playHipHop() gets called and so on. Overview of the Issue However, in reality, when I press button 0, the music plays the first time but none of the buttons work for the second time. If I remove playtestSong(); then remote works fine. The print statements inside the if statement for respective buttons gets executed. For example, if I press button 1 ..read more

SoftwareSerial issue

Im working on a project involving an Arduino nano 33 BLE rev2, and am working on a Mac. There is an HC-05 bluetooth module connected to it, and I'm trying to receive IMU data, namely from the gyroscope and accelerometer, and output it to either the serial monitor or to a separate text file. I saw a YouTube video that did such a thing, and it involved using SoftwareSerial to, as I understand it, change the TX and RX pins to different pins. When I run the code that includes #include <SoftwareSerial.h>, it tells me that the file or directory can't be found. I thought that it was included w ..read more
