ARDUINO QUESTIONS

hop of those help? Yeppee..!! I solved the error. There is a little change in the library of HX711. Change in shiftIn function as shown below:

may help you . As for the button changing from 0 to 1 too often, that is switch bounce. Google that. There are innumerable articles on something called "debounce" that will solve that issue. As for sending the signal only once per press of the button

wish helps you i am converting pixel array to String and send this String to arduino. but i Think this String is not converted properly because Serial.write send (8 bit or 8 character) i don’t know. and also want to send 100 character of string into

like below fixes the issue ok, analogReads normally do have a little oscillation, its normal! they are measuring voltage values and depending on the sensor you are using they will oscillate, same idea of measuring voltage using a multi meter. if you

TAG : arduino

it fixes the issue As long as you use WiFi.softAP(), you do not need to explicitly configure a DHCP server on the ESP32. It will happen automatically - the library looks after it for you.Here is a minimal example, where - in addition to setting the E

TAG : arduino

it should still fix some issue Pins 0 and 1 on an Uno are used for serial communication.As soon as you did Serial.begin(9600);, you enabled those pins for serial comms, so you can't also use them as standard digital pins.

wish of those help to the Arduino Forum User: leongjerlandI was able to fix the issue. The code as below,

TAG : arduino

it fixes the issue After further investigation and by coincidence, it came to my mind the idea that the Arduino was in fact not giving me a PWM analog voltage but a frequency, which a bit of testing with the help of an oscilloscope confirmed. So the

may help you . By definition, firmware means the permanent software programmed into a read-only memory. So, two categories of firmware are used in Arduino: I) Bootloader II) User's Customize firmware.Just like we flash to install/update EEPROM firmwa

TAG : arduino

I wish this helpful for you As discussed in the comments above, the issue is hardware related.On the Arduino Mega 2560 board there are two resistances tying lines SDA and SCK (pins 20 and 21 on the connector) to +5V.

I hope this helps you . Have a look at the datasheet of the relay. Your relay is fine for:

TAG : arduino

help you fix your problem Well, first thing I'd advise you to get a logic analyzer, such as the logic or the openbench or the buspirate or an arduino based one (or any other more expensive options that can interpret i2c). Then, you'll see if there is

TAG : arduino

hope this fix your issue on arduino UNO, attachInterrupt works only for pin ID 0 (pin digital 2) and ID 1 (pin digital 3), you can't use it for any other pin.Using register directly you can use CHANGE interrupt on any pin, but this can backfire as th

TAG : arduino

it fixes the issue The lag is caused by the digitalWrite-calls. Your processing application waits until digitalWrite has finished and this may take 0.05 seconds or so. To fix your problem I would save the current time in milliseconds.

TAG : arduino

like below fixes the issue I think you might be building against Arduino Uno which is not supported for now. Our example works with Arduino Nano 33 BLE - you can find it in the board manager.

this one helps. I am using Arduino Nano, Bluetooth module HC-05 and one push button. I want to rotate the motor when it receives signal from the Bluetooth and stop the rotation when the push button is pressed but here the Bluetooth signal should not

TAG : arduino

wish help you to fix your issue The base of the problem: I have an Arduino Due and a MPU6050 accelerometer and an 23lcv512. MPU gives me 16bit signed integer. I would like to save the datas to the SRAM and after the measurement read them back and via

TAG : arduino

this one helps. , Your void loop is empty.

TAG : arduino

it fixes the issue Arduino (Nano, Uno, Mega etc.) can communicate via SPI, I2C or UART. Long story short, SPI is not suitable for your application. It is used for fast data transfer over short distances (usually milimeters or centimeters), so mainly

TAG : arduino

Does that help The strtol() can't handle a String Object as input. You must convert it into a character array.

TAG : arduino

I wish this helpful for you I'm working on a project using an arduino uno board, I'm using an External interrupt tied to a switch I wanted this switch to work only if i sent an activation order to the board The Problem is that, if the switch is press

TAG : arduino

like below fixes the issue It works the same way as standard C++. You can declare a pointer in the global scope and then use the new operator on other scopes to dynamically create an object anywhere you wish.

TAG : arduino

I wish did fix the issue. You have an if statement.Straight after that, you have another if statement, with its own else.

TAG : arduino

I wish did fix the issue. Just implement a simple serial protocol. No need to combine your sketch and Firmata.If your PI's job is to visualize and provide a user interface all it needs to do is continuously receive values and send commands on demand.

TAG : arduino

it fixes the issue You are trying to read the serial buffer even when there are no bytes to read. See your if statement.

TAG : arduino

I wish this help you Can you hook it up? Well technically you also could stick a fork into a power socket. Either of which is ill advised.No, you can't drive a 4 ohm speaker with an Arduino directly.

TAG : arduino

I hope this helps . I found a page that looks like documentation for the playFullFile() function. It says that the parameter must be a char * - that is, the parameter must be a character array. A String is a completely different thing than a char *,

TAG : arduino

hop of those help? The String class handles a char array buffer allocated in heap memory. The object of class String only has a pointer to this buffer. If you store a String object to EEPROM, you don't store the buffer and after retrieving the object

TAG : arduino

will help you So you have multiple ways to pair those two devices. The best and most reliable is a serial connection which consists of 2 wires, RX and TX which are flipped(RX of one board to TX of other, and TX ->RX). The reason for this is very simp
