The Arduino reference is not listing try catch (for details of why see, for example, this related answer). And I assume, that implementing try catch on a µ-controller could be kind of difficult/impossible. Try catch in most languages is a quite expensive operation: The program stack get copied once for the try block and for … Read more
Good afternoon, I recently assembled an ATMega328P based micro-controller PCB of my own design. I feel good about the circuit itself as I managed to upload the Arduino Blink sketch via the Sparkfun AVR Pocket Programmer. After uploading this sketch I noted that the ATMega was using its internal oscillator. I didn’t feel comfortable changing … Read more
You should do a few checks in order to jump to a conclusion, your Arduino may be just fine. As far as I know, Code cannot destroy a controller. Check if any other software is using the same serial port. Two softwares cannot use the same serial port at the same time Restart your PC … Read more
I am trying to use NOD MCU ESP8266WiFi with Arduino IDE When I run this code: I get the following error:
I am trying to use NOD MCU ESP8266WiFi with Arduino IDE When I run this code: I get the following error:
| performs a bitwise OR on the two operands it is passed. For example, If you look at the underlying bits for 0x0A and 0x50, they are 0b00001010 and 0b01010000 respectively. When combined with the OR operator the result in b is 0b01011010, or 0x5A in hexadecimal. |= is analogous to operators like += and -= in that it will perform a bitwise OR on the two operands then store the result in … Read more
This is how I solved the problem. In Device Manager you will find the Arduino COM port. Go to the Advanced properties of the port Set the COM port number to COM1. Then replug the USB.
I get this error message when i try to upload code to my arduino. Does anyone know what is going on? I have installed the proper drivers and it works fine. My port appears on the menu and it is the corresponent to the device. bless

This is the main error that I get when I try to run my ARDUINO program. The full list of errors is as follows: My code is as follows: I have tried updating the drivers (they are fully updated) and downloading some programs. I have Windows 7 and my arduino is a MEGA 2560. It … Read more
