DIY Raspberry Pi RGB LCD HAT
Raspberry Pi Hats are the same as shields for Arduino, they can directly fit on the top of Raspberry Pi and don’t require any further connections. Here we are going to build an RGB LCD Hat for Raspberry Pi on PCB. This LCD Hat consists of a 16×2 LCD module, five switches, and three NeoPixel LEDs. Here switches are used to change the text on display and NeoPixel LEDs are used as indicators. These switches and Neo Pixels can be programmed according to requirements like switches can be used to display sensor values like temperature, humidity, etc. and Neo pixels can be used to display status like Red for indicating some error and green while receiving some data.
