In the above equation, as the value of R2 changes, the Vout scales accordingly with respect to the input voltage, Vin.Typically, a potentiometer is a potential divider, which can scale the output voltage of the circuit based on the value of the variable resistor, which is scaled using the...
In this case, we are using a hardware interrupt that is triggered by a state change on one of the digital pins. Most Arduino designs have two hardware interrupts (referred to as "interrupt0" and "interrupt1") hard-wired to digital I/O pins 2 and 3, respectively. The Arduino Mega has...
I wanted to use a keyboard as an input to arduino without using a chatpad. any way to use a mordern keyboard as an input to arduino(the keyboards with touchpad)? It will be a complicated project though!Sign in to reply element14 是第一个专门为工程师服务的在线社区。 与您的同行联系并...
Lots of microcontrollers these days have USB ports on them, to program or debug, act like a keyboard or disk drive, or simply send data between a computer and your firmware. But did you know that you can also add a USB Host port? That means that your microcontroller project can have a...
In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code

This Arduino Board can act as HID (Human Interface Device), as a keyboard or mouse and send keystroke through the USB port like a real keyboard. When you connect the Arduino to the USB port of the PC, it will act as a keyboard and send keystrokes. ...
