Hi all, hope you are are staying safe and being alert! I am hoping to make a robot, using a recently purchase remote control and receiver unit. The receiver has 3 channels and on testing reverses polarity giving I suppose 6 channels. (I guess they are usually driving simple DC motors) I note with the meter that the voltage out on each channel is equal to the voltage of the batteries used (4.5/6v)
My initial idea was to use the voltage to trigger relays that would trigger the input pins. (I want to drive Steppers and possibly some servos as well). Whilst thinking about it, I realised it might be OK to use the voltage output of the receiver unit to directly drive an input pin, thus negating the use of relays. This is my first time using remote control as a mean of control. My questions therefore are:
1.Can I use voltage to trigger an input (4.5/6v) or do I need to reduce the voltage into the input pins?
2.Am I to use the pins that have DAC or am I misunderstanding their role?
I have Picaxe 14 or 28 to use (m2)
Many thanks in advance.
