I'm new to Picaxe and would like to start with this project. I don't have much experience in programming anything except a little Visual Basic on the PC. I have already experimented with the Picaxe Editor / simulator and I'm suprised how simple the basics are.
I've built a battery tab spot welder which I'd like to upgrade with a Picaxe controller. The welder uses a 12V car battery, 10x irf1324 mosfets and a MCP1407 mosfet driver which I'd like to control with the Picaxe. The Picaxe should generate a short pulse ( a few ms), a short pause and a welding pulse (5-50ms). The pulses will be adjusrable with a potentiometer but that's pretty simple.
My questions are:
- Will the Picaxe generate these short pulses accurately (enough)?
- The mosfet driver needs a >1.8V logic HIGH and <1.3V logic LOW input so it can be connected directly to an output of the Picaxe? Do I need a pulldown resistor on the Picaxe output?
Thanks!
