hi peeps,

i’m looking for a way to average 5 value’s to a single number to start a calculation and then print it to an 16x2 lcd

i’"m making a beer color measure device for my homebrew club and the idea is that a 430nm led wil licht up 5 times and an ldr takes 5 reading than average the numbers and makes a calculation and prints the value on an lcd screen

any advice ? i don’t understand anything about computer code i’m just a simple welder

Hello and welcome.

Well, you need something like:

![avg-measure-main](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/e869cd03aeebb887191443cca650f28f35f191de.png)

But, there’s no such node as `avg-measure` in XOD standard library (yet). No problem, you can make your own:

 ![avg-measure](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/e2828252205a600fec1dd5b1883a11ce1b2be591.png)

The basic idea is to trigger N readings and store their sum with `count` node. When N readings are accumulated, pass the result of the “sum / N” to the node output.

I didn’t check it for myself but hope I gave you the necessary direction. A xodball of the project is attached: [lets-make-a-beer.xodball](https://forum.xod.io/uploads/xod/original/1X/d4c8ddd78b68891e264f8fec6d60ea5e5d8501d4.xodball) (7.3 KB)
