NerdKit

My NerdKit arrived last week. I haven’t had as much time to play with it as I’d have liked, but it’s still awesome. I’ve built the first two examples, a temperature sensor and a binary adder. I’ve modded the adder to light up a couple of LEDs depending on the sum, which taught me how to set pins as output and drive them high or low. It’s all done with bitshifting and logical operators. The variables that control things like input or output are stored in 16 bit integers (if I recall correctly). Each bit stores a boolean value referring to a single pin or setting. With some nice logical operations, it’s possible to retrieve a single bit, or change a single bit to a 1 or a 0. I might write a guide about this someday.

 

So, what should I tackle next? Should I upgrade the binary adder into the binary RPN calculator that I talked about before (this would require buying some more switches) or should I try to drive the piezoelectric buzzer at frequencies corresponding to musical notes and make music? How can I choose?!

    So your NerdKit arrived then! Interesting….. Would I like it?

    I expect that you would like it – how good are you at striping wire? 🙂
    It reminds me quite a bit of our Computer Engineering course in the first year (that was when we first became friends, remember?), only with more power at my disposal.

    I remember!! You was my lab partner, and I was a young fresh chicken in the CompSci world! I guess it took you 3 years to know me though 🙂

    I, uh, never realised that you were a chicken!
    “You was my lab partner” – I didn’t realise that you typed in a Staines accent! Well, maybe not in the accent, but that grammar is awful, and you know that that’s something I can’t stand. I’m inclined to think that you’re trolling me… :O
    What’s that bit about taking three years to know you in reference to?

    Hmm… I feel a was/were debate cropping up! ‘Were’ refers to the plural past tense. ‘Was’ refers to the singular past tense. Since “You was my lab partner” refers to you only, then ‘was’ is correct! 😉

    Are you ‘dissing’ Staines? Lol

    I think the next project you should tackle is the Morse code Decoder project; you could also figure out how to display the sending speed in WPM (words-per-minute) on the LCD.

    Please email me your response! This seems like quite an interesting project to undertake with the Nerdkit!

    Interesting suggestions! As soon as I’ve moved closer to work, I shall give it a go 🙂

    Excellent! Be sure to email me (click my name) when you do! 🙂
