Touch Sensor: The ESP32 comes with 10 capacitive touch sensors connected to GPIO pins. RESET Button: This button is simply used to reset the board. This port can also be used to connect the board to the computer to upload programs. Micro USB: The board is powered using an onboard Micro USB port. During the upload, we have to HOLD down the Boot Button. The circuit remain turn ON until the supply is disconnected.Boot Button: This button is used to upload the new sketch/programs to the ESP32 microcontroller. As the Q0, Q1 and Q2 output goes high Red, Green and Blue color LED turns ON respectively. The RGB LED is connected to the three output of the 4017 IC as the output goes HIGH, it turns ON the respected color of RGB LED.

We have used a 4017 decade counter IC which is getting clock input generated by 555timer IC. The given RGB LED Circuit diagram is for Multi-Color LED flasher.

We can use three different LEDs to perform the same task but this will increase the size of circuit and took more space on PCB or perf board. An RGB LED can also be used for work according to condition like for condition 1st Red will glow, for condition 2nd green will glow and for condition 3rd blue will glow. You can use RGB LED in various projects like portable flashlight, LED indicator, etc. Forward Current for Red, Blue and Green color: 20mAĪ RGB LED is commonly used component in electronics, generally, as it is used for indication purpose.Super High flux Output and High luminance.This terminal used for glowing LED in Blue color

This terminal used for glowing LED in Green color This terminal used for glowing LED in Red color
