Is it possible to transmit potentiometer readings wirelessly using a either an xbee or nRF2401 with no microcontroller?
I am a programmer, but a beginner with Arduino. If anybody could point me in the right direcitons it would be very helpful.
The nRF2401 won’t work without an MCU. I wouldn’t bother with it, anyway, it’s obsolete. I’ve used the current nRF24L01+ with a PIC.
The issue here is that there are some very unforgiving size constraints. If I were to use an xbee instead, is it possible to transmit potentiometer readings without a micro controller? How could this be accomplished? Is there another transmitter that is smaller in size that could accomplish this? I only require about 30 foot range.
It should be possible to get an nRF24L01+ and an MCU into a very small volume.
You may not be aware of just how tiny microcontrollers can be. The ATtiny10 is a little less than 2 by 3 mm in the SOT-23 package, and if you can fit the code into 1kbyte, you get a happy little computer complete with an 8-bit ADC to digitize your potentiometer data. Sparkfun sells the [Nordic Fob if you’d like to see an example using a slightly larger Atmel microcontroller.](Nordic FOB - WRL-08602 - SparkFun Electronics)
Yes, XBees have a few Analog (ADC) inputs. Check the XBee Documents on their Pin outs.If I were to use an xbee instead, is it possible to transmit potentiometer readings without a micro controller?
Note: The Series 1 XBees require an external ADC voltage reference.

You can instead nRF2401 by nRF24LE1 or other which consists the 51 MCU, no other external MCU is needed.
