HELLO guys,

TOday i got my first Picaxe board, and i want to make a bulb light up.

---

  This is the board,

 

THis is where im connecting:

 

 I typed in my Piaxe editor,

High 3

Low 3

and a message came saying something about Sucsses and uploading.

but the bulb didnt do anything,

Can anyone tell me why it doesnt work?

After some time of idleness i got to work again on my IR setup. I still have some problem understanding what happens.

This is my setup:

Transmitter: picaxe28x1, IR led (tsal6100)with cathode connected to pwm (%50 duty, 38000Hz), anode to an output pin.

Code:

pwm bla bla (set up of pwm)

pause 500

pulsout 7, 250

 

Receiver: picaxe28a, IR receiver and demodulator (tsop1238) properly connected.

Code:

debug 

main:

pulsin INPUT_PIN, 0, w0

goto main

Hello! i have almost finished my analog inputs on my last project.. i have only one left and i need to attach some potentiometers to do some calibration.. I could really use some nice multiplexing. What i'd like is a chip with some analog inputs and possibly an i2c interface so that you can choose which analog pin to read and get a digital reading. Do you know if anything like this exists ?

im thinking of making a robot that could follow one's feet, by using infrared.

the idea would be to use two or more infrared LED's and attach them to my Shoes and then two infrared sensors on the robot. it would roll a bit, then read witch sensor riceves more IR light, turn that way, roll, and repeat.

any chance it would work? Or am i just talking crazy talk?

 

 

I thought i'd make this post to help any beginners that also run into this problem, i wasted a good hour and a half on this, so hopefully no one else has to.

I have an idea of how to do a electronic speed control for some DC motor (H-bridges).
I built this circuit and it works pretty well.  Its a PWM generator based on this great tutorial .  I had to convert it to a NE556 instead of a NE555 but it works well with a 100K linear pot..

 

how do I solder a wire to this so that I can use a microcontorller to trigger it via outputs?

Has anyone had any experience with the SPE030 speech synthesizer? I just want to know what it sounds like, I've done a google search but didn't come up with anything.

 

Thanks 

Stuff the board does which you wish it didn't.

Hi guys! i want to introduce to you (some already know about it) this game. It's a guitar hero clone, and for the ones who don't know what it is, well, it is a game in which you have to impersonate a guitarist and play famous songs with your keyboard or "toy" guitar. You basically see various kind of notes (which are basically small dots on the screen) scrolling down towards you and your goal is to get as many as possible.

Kind of hard to explain....why don't you give it a go? :D
