Grove Zero - Slider
• What is it？
The Slider is commonly used to control electrical devices such as the LED dimmer of light or a volume fader seen on an audio equipment.
• How it works？
The Slider is a kind of ‘potentiometer’, which is a variable resistor used for measuring electrical voltage as well as current control.
As you slide the bar all the way from the left to the right, it’s sending a voltage signal from 0 to the 3.3V, but in fact you are reading 0 to 1023 as the signal is converted into digital signals.
• Try it
Connect the circuit shown below, then slide the bar of the Slider module and see wh will happen.
