Node.js and Raspberry Pi
Node.js Raspberry Pi - GPIO Introduction
Using the GPIO for Output In this chapter we will use a Raspberry Pi and its GPIO to make a LED blink. We use Node.js with the onoff module to control the GPIO. To get a LED light to turn on, we use…
Using both Input and Output In the previous chapter we learned how to use a Raspberry Pi and its GPIO to make a LED blink. For that we used a GPIO pin as "Output". In this chapter we will use another…
Using Array With Output to Create Flowing LEDs In this chapter we will use several GPIO pins to create a "flowing" effect by turning them on and off in sequence. What do we need? For this you need: A…
Node.js and Raspberry Pi - Webserver with WebSocket
Using Pulse-Width Modulation In the previous chapters we have learned how to use WebSocket, and how to use GPIO to turn LEDs on and off. In this we will use chapter we use a RGB LED, with PWM (Pulse-…
