I am new to electronics and as a fun project I thought I would try to interface the arduino with a wireless reciever and an RC transmitter and basically program my own esc (electronic speed control) and mixer.
It seems that the arduino's analog reader will output a value between 0-1024 which maps between a voltage between 0-5volts. I was reading the voltage that comes from the reciever and it only seems to output a voltage between .374v to .220v so it basically always reads 0 from the analog reader. So I was wondering if there is anyway to modify the levels of the arduino to reader a much lower and finer voltage or if there is an easy way to multiply the voltage coming from the reciever?
Any help would be much appreciated.
