I have recently purchased a Traxxas DC brushless motor and ESC. Here is the link of the motor:
I also purchased a transmitter and receiver to work with the equipment, receiver link below:
I was hoping to take the receiver out of the loop and replace it with an Arduino. Hooking it up to an oscilloscope, it appears that the receiver is giving a 325mV or so signal. I am able to copy the on/off time with an Arduino, but it is outputting at a much higher voltage (it is exactly 10x the voltage, around 3.3V).
How do I step down this signal from 3.3V to .33 volt so that the ESC will respond? I have been looking into step down DC-DC converters, but the closest output voltage I have been able to find is 0.8V.
There is a calibration process for the ESC. Maybe that can be calibrated to respond to the higher voltage input, but I have tried the process and that is not working, either.
Can anybody help?
