Connecting Motor Driver to Arduino UNO Pin number 1 and 9 are the enable pins, we connect these two pins to a 5v input to enable the motor. Pin number 1A, 2A, 3A, and 4A are the control pins. For eg. The motor will turn to the right if the pin 1A goes low and 2A goes high...
How to get Arduino received value using Matlab? I tried to transmit string using Arduino. Now i need to connect to matlab and show the received data using mathlab. How can i do it? This is my arduino code #define LED_PIN3 #define LDR_PINA2 ...
One of the most useful things you can do with anArduinois control higher voltage (120-240V) devices like fans, lights, heaters, and other household appliances. Since the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch t...
Connect all the 3 pins of the push buttons to the 5 volt output on the Arduino. It’s helpful to have a clearer picture of theArduino’s structure. After connecting the buttons to the 5 volt output, the other end goes to analog 1, 2 and 3. After doing the connections, upload the ...
You can use a microcontroller, such asArduino, to create the logic for when to turn your lamp on and off, then use an electrical relay to do the switching of the lamp. This makes it easy to make lights that activate only at night, control your garage door motor with a signal generated...
any obstacle, an LDR to sense lighting conditions and an RF remote which the blind man could use to remotely locate his stick. All the directions will be given to the blind man through a Buzzer. We can use a vibrator motor in place of Buzzer and advance a lot more using our creativity...
The servo motor has three pins; 5V, GND, and PWM. You need to connect the PWM pin to an Arduino pin that can output PWM signals, such as D9. Making a box for the sugar dispenser is the most difficult part of this project. You may create it the way I did below, or use your ...
Also known as Light Dependent Resistors (LDR),photoresistorsare light-sensitive devices. They are most often used to indicate the presence or absence of light. In low light, the resistance is very high and drops dramatically when exposed to light. It is made of a high-resistance semiconductor...
