How to Use LED Tactile Button Using Visuino & Arduino

In this tutorial, we will explore various ways to use an LED tactile button with Visuino and Arduino.Example 1

: The LED on the button will turn ON or OFF with each button press.Example 2: The LED will oscillate between ON and OFF states when you press the button to activate it.Example 3: The LED will gradually dim or brighten when you press the button.Example 4: With each press, the LED's brightness will increase. Once it reaches maximum brightness, it will reset and start from the lowest brightness.Example 5: Pressing the button will toggle the LED's blinking state—starting or stopping the blink.

Connect Arduino Digital pin [2] to Tactile Button on the breadboard and to the Resistor1Connect other side of the Resistor1 to the breadboard pin [GND]Connect Other pin of the Tactile Button to the breadboard positive pin [5V]Connect Arduino pin [5V] to breadboard positive pin [Red line]Connect Arduino pin [GND] to breadboard negative pin [Black line]

 

Connect Arduino Digital pin [3] to the Resistor2Connect Resistor2 to Tactile button side pin [+]Connect Tactile Button side pin [-] to breadboard negative pin [Black line]

 

Note: Most of the Tactile Buttons have a red dot on the GND pin, this way you can correctly connect it

The LED will gradually dim or brighten when you press the button.

Add "Debounce Button" componentAdd "Toggle Flip-Flop" componentAdd "Digital Multi Source" componentAdd "Detect Edge" componentAdd "Analog Value" componentAdd "Ramp To Analog Value" component

 

Select "DetectEdge1" and in the properties window set "On Rising/True" to FalseDouble click on the "AnalogValue1" and in the Elements window drag "Set Value" to the left side and in the properties window set "Value" to 1Drag another "Set Value" to the left side and close the Elements windowSelect "RampToValue1" and in the properties window set "Slope (Sec)" to 0.5

Note: to change the Dim or Brightness time adjust the "Slope (Sec)" value according to your needs

With each press, the LED's brightness will increase. Once it reaches maximum brightness, it will reset and start from the lowest brightness.

 

Add "Debounce Button" componentAdd "Up/Down Counter" component

Note: you can also use just the "Counter" component

Add "Integer To Analog" component

 

Select "UpDownCounter1" and in the properties window set "Max" > "Value" to 5 <<This means that we will use 5 steps for brightness, since the "Roll Over" is set to True it means that once we reach 5 it will start from 0Select "IntegerToAnalog1" and in the properties window set "Scale" to 0.2 <<Brightness step, you can adjust the number

 

Connect Arduino digital pin [2] to "Button1" pin [In]Connect "Button1" pin [Out] to "UpDownCounter1" pin [Up]Connect "UpDownCounter1" Pin [Out] to "IntegerToAnalog1"Connect ""IntegerToAnalog1" pin [Out] to Arduino Analog PWM pin [3]
