New stuff arrvied! :D

Yupp, just a short little update.

I got the RF sender & receiver from Sparkfun today!

RF Link 2400bps Receiver – 315MHz
RF Link Transmitter – 315MHz

Also a 20×4 serial LCD, gonna be useful for advanced applications. Anyhow, if you got the RF kit, and was like me wondering how to get it working. I found this nice guide at LMR.

Now it’s just to find a nice way to use the RF links, it’s only one-way communication, but it’s gonna be awesome to use it as a remote for one of my robots!

My Arduino Robots

Category : Arduino, Electronics

Thought I write some about my two robot projects! They both use a Modified Pico, since it’s the smallest Arduino I’ve found. And it also fits on a small breadboard!

Botty 2:

This is the most advanced robot I’ve built, but it’s not nearly finished.

It’s current task is to drive straight forward until it senses a object with it’s IR-sensor, then drive away from it until it’s cleared, and continue in that direction. Really simple 😛

It uses a Sharp-IR sensor, mounted ontop of a servo, so it scans the horizon while driving forward. The sonar in the picture isn’t in use, since I actually like the IR sensor better.

BewBit:

Simple and yet fun to make arduino bot. Just follows the strongest light source. Using two LDRs, a modified pico and 1xAA and 2xAA battery packs, to give out 4,5 volts. Just enough to power theSN754410 and motors. But it gets around. It also includes a low-voltage alarm, which beeps when the voltage goes low.

Had a little accident, it drove over a carpet, or it came about 30cm into it and some funny gear-whining noise came 😛 A lot of hair in the gearbox, had to take it apart and clean it.

Future plans:

* Crash sensor, a small micro switch in front.
* Speaker, plays sound according to light source 😛
* Better code

My new Serial LCD arrived!

Got my Serial 16×2 LCD today, I’m still quite noob when it comes to serial. But I’m gonna put out some simple and easy to follow tutorials for stuff when I get the hang of it 🙂

Anyhow, here’s just a little youtube clip showing some of my projects today!
