Jan 22, 2015 · Using Arduino IDE 1.x. MaartenArduino January 22, 2015, 7:01pm 1. When I connect my first Arduino Uno board with the USB cable to the PC, the green light on the board lights up, and the orange light goes into the blinking mode - indicating that the board is working. But NOTHING happens on the computer (tried it on the PC and a laptop - both ...

Nov 21, 2014 · Say your code was talking at 4800 - then you adjusted the system speed from 16 MHz to 4 MHz. Your code would need to change the serial speed to 4800 x 4 = 19200 so it would still look like 4800 to external devices. Using external crystal: if using other then 8 MHz or 16 MHz is used, Riva has addressed that already.
Dec 19, 2011 · Development Other Hardware Development. nickgammon December 19, 2011, 1:08am 1. I'm working on a bit of documentation for the new Uno, and am wondering the purpose of the JP2 jumpers. Judging by the schematic, they connect PB4 to PB6, and PB5 to PB7, on the Atmega16U2. Can anyway say what the purpose of connecting those jumpers might be?
Sep 12, 2024 · As you may know, Arduino Uno R4 is great, but NOT fully compatible with Arduino Uno R3. Therefore, I created a series of Arduino Uno R4 tutorials for beginners I tested Arduino R4 WiFi with components such as keypad, OLED, LCD I2C, various sensors.... If a library works with Uno R3, but not for R4, I find other one. For example, Arduino UNO R4 - Keypad 3x4 We also improve some mistakes that ...
Jun 15, 2017 · But rfid and arduino are supposed to communicate through hardware serial af baud rate of 115200 . That may not matter. I don't know what your project actually does, and nothing about the data stream except the baud rate, and you need to be more forthcoming about both. Even if software serial was fine at 115200, Arduino is not going to work like ...
Jul 6, 2014 · Anyway. It was possible to upload sketch in following way: 1.) connect the arduino to the port showed in lower right corner of IDE (because of the communication problem you can't choise port in Tools->Serial Port) 2.) press button 'Upload' when you have open your (error-free) sketch. 3.) wait until compiling completes.
