bt7csr on WRL-11664 - XBee Pro 900 XSC RPSMA
How difficult (or even possible) would it be to have this connected to an Arduino Micro? And, I don’t care if Sparkfun charges twice as much as digikey for this. The vast amount of information and...

I would like to know if this sensor could be connected to a phidget 8/8/8 as a simple analogic sensor? I already have the env-tmp made by Atlas scientific and it looks like the sensor must be told to...

This is only a guess, but if you’re using the I2C / TWI / “Wire” interface, I have occasionally had issues with the Arduino Wire library locking up due to an I2C transaction going bad and the library...

This is not an analog sensor like the TMP36. This sensor has a “1-Wire” digital interface, which requires the host system to send it a special digital command sequence to get the temperature reading,...

I just received my order and it appears mine came with the two servos. I ordered 2 claws (ROB-11525) and 2 medium servos (ROB-10333), the pan/tilt bracket (ROB-10335) for the head and 2 small servos...

This board runs at 3.3V, so if you are connecting it to a 5V device you will want a logic level converter. The Arduino Uno runs at 5V, not 3.3V so you will want a logic level converter to connect this...

It depends on what you mean by ‘software solution’. This outputs basic serial data, so you could use any program that reads serial data such as CoolTerm, TeraTerm, Hyperterminal, etc. You could also...

How can I use this to charge a lipo battery less than 500mah such as this guy? I don’t quite understand where I’d place a resistor to reduce the current coming in from the micro USB port.

+1 I’m also unclear how you’d add a resistor to the basic charger to step the current down to 15mA.
