This is a simple slide switch for LilyPad. Use it as a simple On / Off switch, or to control LEDs, buzzers, sensors, etc.
The switches in each panel have a capacity of 4V to 300 mA, but will operate at 5V with a current reduction.
Lilypad is a wearable E-textile technology developed to have large connection pads to attach to clothing. Lilypad Slide Switch Board 2 Positions Interruptor features:
- Switch two positions: On (ON) / Off (OFF)
- Density of the PCB: 0.8 mm
- Size: 7.75x18.1 mm

ESP32-S3-DevKitC-1-N8 general-purpose development board based on the ESP32-S3-WROOM-1 chip.

It is the freshest serial LCD from SparkFun. Similarly to other SparkFun LCD screens it is put on single board with a microcontroller, however in contrast to the other screens in our offer (SP027 and SP028) it is based on PIC16F88 rather than ATmega328.

This module specially designed for Arduino will allow you to generate a light of any color (RGB) quickly and accurately.
The LED Bulb Module RGB, consisting of an LED capable of creating any color using RGB, has a PWM voltage input with three pins. These are capable of shining in a wide range of colors thanks to the mixture of the three colors. primary (red, green and blue).
These types of diodes are called RGB and are made up of three red, green and blue diodes in the same package.
Thanks to the variation of the intensity of these three diodes, we can create a composition of colors. With this led you can handle more than 16.5 million colors.
