I've been using many different Picaxe's for quite a while to develop different types of robots but ive never used or touched an Arduino.
i was thinking of buying one except i have no clue about the different types. is there a certain model that is simple to learn the basics with and are there any extra parts or tools i need to use Arduino.
I recently received a Bluesmirf Gold module from little bird electronics and am struggling to connect the Picaxe to Pc using bluetooth. when i open the bluetooth icon in the taskbar and press "add" it finds a device named "FireFly-16FF" i am asuming this is the bluesmirf module.. i stabilise a connection with the option "no-passkey" selected and everything seems fine. the module is wired up to the picaxe Serial in and serial out pins and i am using the serrxd command.
I have been using a simple Black/white detection circuit with my picaxe to make a line following robot.
i wired up a circuit like the one below and programmed the Picaxe with the code below.
basicly what it did was when the IR LED/Phototransistor pair detected black it sent the number 1 to my computer and when it saw white it sent the number 0. this worked fine with the circuit wired exactly like it is below, but when i changed the Picaxe input to a different pin it just kept constantly sending 0's to my computer.
