When plugging the Arduino Nano 33 IoT and the Motor Carrier, some of the pins will stop being available for you to use in your code, as they will be needed to control some of the features of the Carrier. For example, some of the pins of the Nano will be used to control 2 of the...

Ideally, you would control the board by holding 1 input LOW and applying a PWM signal to the other input. This allows for easy speed control. I have written into the code that if you bring digital pin 7 HIGH, the code switches to Relay mode and either turns the mosfets all the way O...
you should see a small status window. This will report the progress as the code is compiled and then uploaded to the Arduino. While the code is being uploaded, you should see some very small LED lights (the Transmit (TX) and Receive (RX) lights) on your Arduino board blinking as the ...
Arduino Traffic Light Code It’s now time to write some code to bring our lights to life. If you have programming experience, then you will find this code really basic. If you’re new to programming, then this is a great way to start learning all the basics. First, we will need to...
Running an Arduino program has two steps: the first is to compile the code on your computer in the Arduino IDE. You can do this by pressing Ctrl+R (⌘-R on OS X). Once your code compiles, you upload it to the Arduino board using the Upload to I/O Board button on the Arduino...
For the IDE to send the compiled code to the board, the board needs to be plugged into the computer, and you need to tell the IDE which board and serial port you are using. When an upload starts, whatever sketch is running on the board is stopped (if you were running the Blink sket...
Theater Chase Rainbow- Theatre-style crawling lights with rainbow effect. Inspired by the Adafruit examples. Running Lights- Running lights effect with smooth sine transition. Twinkle- Blink several LEDs on, reset, repeat. Twinkle Random- Blink several LEDs in random colors on, reset, repeat. ...
Huge thanks toRalph Doncasterfor providing his excellent picoUART library and his oscillator calibration code. None of this would be close to possible if it weren't for his brilliant work! Programmers When the ATtiny13 is running from the internal 600 or 128 kHz oscillator, it may be too slow...
