2.7 - Toggle Left and Right

The slide switch is a 3-pin device, with pin 2 (middle) being the common pin. When the switch is toggled to the left, the left two pins are connected together, and when toggled to the right, the right two pins are connected together.

Schematic

GP14 will get a different level, when you toggle the slide switch to the right or left.

The purpose of the 10K resistor is to keep the GP14 low during toggling (not toggling to the far left and not toggling to the far right).

The 104 ceramic capacitor is used here to eliminate jitter.

Note

• You can open the file 2.7_toggle_left_right.ino under the path of kepler-kit-main/arduino/2.7_toggle_left_right.

• Or copy this code into Arduino IDE.

• Don’t forget to select the board(Raspberry Pi Pico) and the correct port before clicking the Upload button.

When the program is running, the serial monitor will show “ON” or “OFF” when you toggle the switch to the left or right.
