    08M2 Parallel processing help needed

    Hi - I'm trying to get some parallel processing going, but struggling. Any help appreciated! C3 is a PTM switch, C1 and C2 are LEDs. The circuit works with a single program - am I doing something wrong here? start0: do if pinC.3 = 1 then low C.1 high C.2 endif...

    Modifying a PWM signal - Hacking a RC car!

    Hi, I am trying to reduce the speed of a RC car. It's a cheap chinese one, and I think it uses one of these http://www.ti.com/lit/ds/symlink/drv8833.pdf to drive the motors. Is there a way of somehow taking the PWM output from the above motor controller chip and reducing the duty cycle? Any...

    Remote Control Car application query

    Hi Picaxe, I wish to use Picaxe to remote control a car. I wish to create a new controller, and there are several motors on board (please see diagram) I need to use a module to transmit the signal to the car. As you can see from the diagram, Rotary switch 1 operates motors 1 - 4...

    Another Picaxe Stopwatch

    Hi, If I outputted 1Khz/ms into this, https://goo.gl/O8Whev, would it be a millisecond timer? If I wanted 4 independent timers, should I have 4 picaxes and displays, controlled by a master picaxe? thanks

    Arc Lighter Project

    I have an arc lighter that has a 3.7v 220mAh Li-ion battery, and a micro usb port on a little pcb for charging. I would like to incorporate it into a project, and use the battery to power a picaxe circuit that activates other components eg a motor, and also the arc from the lighter. I would...

    Blockly only saves as xml

    I have been using the Blockly compiler in PE6 and also on the website, but I can only seem to save the files in xml, which I can't seem to do anything with. Judging by the instructions I should be dealing with .axe files. Am I doing something wrong? Thanks

    input voltage query

    I am using a picaxe 08/M powered by 6v, as per instructions in the datasheets. Is it ok to activate an input using 9v, configured with a 1k protection resistor an a 10k pull down, as per the datasheet?

    RC car problem

    hello - this isn't directly involved with picaxe, but I'd appreciate your thoughts anyway! I have just bought a couple of cheap RC cars for my kids, and of course they use the same frequency. I thought I would replace the crystal. The handset was easy enough to desolder, but I can't see the...

    troubleshooting nightmare

    hello please help - i am trying to troubleshoot a circuit but I am really stuck. I have a pic chip outputting to 2 4511bs, and then to a pair of 7seg leds for counting up to 99, powered by 2 3v lithium coin cells. I have checked the circuit a squillion times, everything is wired properly and...

    how can picaxe recognise different sounds?

    If I made noises of a specific frequencies at a picaxe chip, I could probably hook a mic to an analogue input and get a different output for each different frequencies. If that is the case (please correct me if I'm wrong!) could one then just miss out the speaker/mic bit and send the output...

    how many variables can one create?

    I'm doing a project and I want to know how many variables I can create. I plan to use readadc and store a sequence of values into a corresponding sequence of variables, and then create a specific output combination depending on those variables. I would also like to store these variables so they...

    how to make a trip switch

    anyone know how to make a trip switch? I am driving a motor using a bcx38b, and I'd like to ensure that the current does not go above the recommended 800mA. Fuses are a bit primitive but I don't know of another way. Any help appreciated.

    how to identify chips

    How do I tell whether a chip is an A or and X or an M? Specifically the difference between 08 and 08M would be good. Thanks

    infraout rocks at 38kHz

    thanks for help on 38kHz modulation, Dippy's figures just got too scary for me :) (see post in last forum) - thanks all the same, Dip. 08M infraout does the biz. question - the output only lasts for a second and then won't repeat until input is off and on again. Why? Tx. Edited by -...

    how do I modulate an IR LED at 38Khz?

    I am trying to create a IR circuit, where a IR LED activates a remote circuit. There's no data to transmit, just on and off. I have used one of these http://www.vishay.com/ir-receiver-modules/ I have found that I have to modulate the LED at 38khz. A pulseout command would do the 'mark' bit ok...

    PC output to PICaxe query

    Hi What is the best way to send a signal from a PC? Ideally, I could use a USB output, as these are so common. A simple on-off would suffice, and if possible one that could come from a Flash interface. I would like to create a control panel on screen, that could actuate a PIC circuit connected...

    LED display drivers??

    I can find plenty of LCD display drivers, including Rev-Ed, but I would like LED ones. The LCD ones hook up to a pic chip and can be programmed very easily; using seven segment displays involves lots of messing around with driver chips etc. Ideas?
