#Hi!

Guide on connecting a ST7789 display to an Arduino Nano.

I recently decided to order an arduino nano and a tft display from AliExpress. When I looked up online it took me some time to find a clear guide how to connect the display to the arduino, either the display had different pins or it was a slightly different model, but with some trial and error, I managed to get it to work.

What you'll need for this:

1x Arduino Nano
1x AdaFruit 1.3" 240x240 ST7789 display
6x jumper wires or whatever else you can use to connect

	# l33t ruby bot made by yours truly
	require 'discordrb'
	require 'yaml'
	config = YAML.load_file('config.yml')
	client = Discordrb::Commands::CommandBot.new token: config['bot_token'], prefix: config['bot_prefix']

	client.command(:ping, chain_usable: false, description: 'Basic ping command to test if bot is alive or not', usage: 'ping') do \|event\|
	event.respond 'Pong!'
	end
	client.command(:roll, description: 'picks a random number from 1 to 6', usage: 'roll') do \|event\|

	function sleep(n) {
	Atomics.wait(new Int32Array(new SharedArrayBuffer(4)), 0, 0, (n * 1000));
	}

	// where n = seconds
	// remove the * 1000 multiplier in the function to make it miliseconds

	program order;

	uses
	crt;

	var
	a: array[1..10] of char;
	d:char;
	i,c,r: integer;
