    Setting the PICAXE type (14M2) in a new workspace

    Thankyou for helping. Unfortunately, when I click on "Workspace Explorer" tab, it does not slide open.

    Using transistor to switch power on with a push button

    Thank you for the recommendation. I don't have a 2N3904, do you think it may work with a 2N2222?

    Using transistor to switch power on with a push button

    I am trying to turn on a Picaxe board and remain on until the program finishes executing. The problem is that with a single cell LIPO (4.2V fully charged), the output voltage of the transistor switch is 2.4V. I may be using the wrong transistors or trying to do the impossible.

    Using a single cell LIPO to power an 8M2 or 14M2

    I would appreciate it if you would send me a link to the website of one or two of those vendors.

    Using a single cell LIPO to power an 8M2 or 14M2

    I am planning to use an 8M2 or a 14M2 on a project to drive 8 UV LEDs. Considering using a 3.7V LIPO. What can I expect to happen when the voltage of the LIPO drops below 3V

    PWMOUT on C.0 and C.2 of a 14M2

    First, I want to thank you for all the input and recommendations. To answer some of the questions. The glow plugs are standard RC motor plugs. They glow without burning up with 1.2V to 1.7V and roughly 2A to 3 A The reason for using PWM is to be able to supply with a high capacity 3S LiPo on...

    UNABLE TO INSERT jpeg image or include an attachment on a new thread

    When I try to insert an image on a new thread, things work until I click UPLOAD then nothing happens. The same thing happens when I try to attach a file.

    PWMOUT on C.0 and C.2 of a 14M2

    I am trying to drive two glow plugs from a model airplane engine. Using a two MOSFETs (IRFZ44N) attached to C.0 and C.2 on a Picaxe 14M2. I connected the gate of the MOSFET to C.0 and added a 10K pull down resistor. The source connected to ground and the drain to one of the plugs terminals. the...
