Hi, Anyone interested in watching my second version of a WiFi Robot as it comes together, then please bookmark my ongoing build here. I've just finished the Arduino slave peripheral code I'll be using soon, and you can get the full story, along with the demo source here. 1 post - 1 participant Read full topic ..read more

Ciao a tutti, io volevo fare un codice che permettesse di: -far lampeggiare un solo led in un "case" -poi farne lampeggiare altri in un altro case. Come potrei fare? Grazie in anticipo. 1 post - 1 participant Read full topic ..read more

Hello, I am looking for some hardware components to prototype an electronic system with a 3-12V DC brush motor, and two hall sensors with a buzzer. my system will be used to activate a mechanism in two different senses, and will have to be stopped by the activation of the sensors (one for each sense). Finally i have to activate my buzzer in specific case. For the motor, i red that i have to use a driver to control the sense of the rotation, i saw two reference often used, the L298N, and the L297N. The L297N is simpler than the L298N,but seems to be working only with stepper motors. Is it the c ..read more

This may sound stupid, but I'm wondering if I can use a kitchen scale to act as a weight sensor and connect it to my Arduino Uno. It's not important how I gathered the weight value, I just need to have a value of weight so I can use an "If/else" command. I have already used an HX711 and a load cell, unfortunately, I think the HX711 is faulty. I don't have the time to buy another HX711 because this project is near its due date, and buying online is not an option for me. What I meant by "the HX711 is faulty" is that while calibrating, the load cell cannot read any weight. But, I used a multimete ..read more

Hello everyone! I am trying to use the CAN protocol in order to communicate with a CubeMars motor. Did anyone work on a similar project and could help me with this? A fully working solution would be so nice! I have: Arduino Mega Arduino Nano ESP32 NodeMCU WROOM32 Arduino Nano ESP32 MCP2515 module SN65HVD230 transceiver I guess that with all that stuff it should be possible to implement something working fine! Thanks a lot in advance! 2 posts - 2 participants Read full topic ..read more

Hello everyone, I am trying to get the lowest clock speed possible. I tried using the Arduino LowPower library, but this decreases the current draw from 7 mA to 3.5 mA, and i want to get as low as 15 uA in sleep. I am using a standalone SAM D21 which i program with an atmel programmer using Platform.io. I got this code: GCLK->GENDIV.reg = GCLK_GENDIV_DIV(48) | // Divide the 48MHz clock source by divisor 48: 48MHz/48=1MHz GCLK_GENDIV_ID(0); // Select Generic Clock (GCLK) 0 Which from what i've gathered brings the clockspeed to 1MHz, this also lowers th ..read more

I purchased an Arduino Starter Kit a while back, but didn’t start using it until now because another commitment started taking up too much time. Now, however, I am trying to get started with the kit. While trying to screw the Uno R3 board onto the included base, there is a problem with the power connector. More specifically, it appears that the connector’s legs are so long that they don’t allow the board to sit properly on the plastic base. This means that the board will either not be securely attached to the base or that the board wobbles when I’m trying to plug or unplug anything. Is there a ..read more

Hello, I have an application with an ESP32 Cam Module and another ESP32 Dev Module, where I am sending web requests every now and then. In those, I want to pack all the logging I've done (or something like the last 1000 letters with a circular buffer) in a request whenI send one. For that, I need a way to store my output in Serial somewhere. Thats why I want to build a hook which gets set off everytime I send something via the Serial. So, is there a way to do that? I want to thank you in advance for your answers! 2 posts - 2 participants Read full topic ..read more

It appears that debugging support was recently added to the Arduino IDE 2 and the Arduino R4 Boards package for the UNO R4 WiFi board, however, I get the following error when trying to enable debugging within the IDE. embedded:startup.tcl:26: Error: Can't find interface/{programmer.protocol}.cfg in procedure 'script' at file "embedded:startup.tcl", line 26 Furthermore, I understand that a separate hardware debugger is not required with the UNO R4 WiFi as that capability is provided by the on-board ESP32-S3 module. Am I missing something or is the debugging not yet supported for this board? 1 p ..read more

Hey, I'm doing this project where the goal is to control the power of a light source through labview. I have both of those code but at the end of the day I can never contol the light anyone can help me ? float labviewFLT = 0; const byte numChars = 32; char labviewSTR[numChars]; int pwm = 4; // assigns pin 4 to variable pwm int t1 = 0; // declares variable t1 int t2 = 0; // declares variable t2 float a = 5; float b = 1000; int c = 1000; boolean newData = false; void setup() { Serial.begin(9600); pinMode(pwm,OUTPUT); } void loop() { static byte ndx = 0; char endMarker = '\n ..read more
