[Arduino #26] LED helmet “done”

For last two weeks I tried to finish my old project: LED helmet. It has Receiver and Transmitter part. Receiver: 50 LEDs RF 443MHz receiver Arduino nano Batteries Transmitter: two push buttons RF 443MHz transmitter Arduino nano Batteries The LEDs

[Arduino #24] DS3231_weekday_accessible

DS3231 allows you to set and get the datetime from your I2c RTC module. The existing library didn’t allow me to use the weekdays I set.(Or I just didn’t know how to get them.) So I hacked the original a

[Arduino #20] JeeLabs RTC DS1340 tutorial for dummies

It may be inappropriate that I write a tutorial for dummies when I myself am also a dummy. Anyway I decided so because there isn’t really any tutorial out there. This tutorial was born thanks to my TA Sakari. Yes,

[Arduino #16] Bluetooth, RF, XBee and Bluetooth…..

I thought there would be tons of tutorials about two Arduino boards connected via bluetooth but actually not. So I think I will figure out myself. There are two modes for bluetooth module: Master and Slave. Like the name indicates,

[Arduino #15] Arduino + Chuck => Touché

I know, Touché looks fantastic. Though if you find out the instruction, you will be very surprised how simple the process is.(Or how technology nowadays made such incredible thing so easy to do) However you will be really surprised again(for the

[Arduino #14] Benchmark, case study

Two days something came in my mind that “Maybe someone else has done similar stuff”. So I did some research. 1. Daft punk I’ve been their huge fan since high school but never expected them on my Google search result.
