Don’t draw more than 20 milliamps (mA) of current from your Arduino’s GPIO pins, otherwise you may damage it. Such a small current can easily switch on a transistor, and the transistor could in turn switch on a motor,relay(this is another switch controlled by a small current, except...
ok so i am new to arduino. i am trying to have one button turn on the led witch is in pin 13 and another button to turn it off but im having problems. when i press the button it turns on when i let off the button it goes off. here is my code so far. const int buttonPin ...
Additionally, you need to ensure theconnection to the PWR pins of the motor driver module, as shown in the image above. These pins are responsible for connecting the battery input to the Vin pin of the Arduino. If this connection is missing, the Arduino UNO will not be powered. Now that...

I got a project with an Arduino Mega 2560, controlled by Matlab. For some of the Input Pins, I need the internal Pull-Up resistors. How can I activate these? In te Arduino IDE, you can do this by using "pinMode(pinnumber, INPUT_PULLUP)", but in Matlab no such comman...
Note: The “Set” pins of both HC-12 modules are connected to the pins number 6 of the two Arduinos and the two buttons, at the first Arduino, to the pins 4 and 3. First Arduino code: /* Arduino Long Range Wireless Communication using HC-12 ...
Connect 4 wires(3yellow and a green one) to pins on the Atmega IC on the breadboard according to the pictorial schematic above..and connect them to pins 10,11,12,13on the arduino. Also don't forget to attach the +5V and ground wires between the Arduino board and the breadboard. ...
