Re: Sad to see that the Redboard is gone.

I know that an older revision of the Redboard and the SIK with the older revision Redboard. Can be purchased on a surplus electronic equipment and component web site.
So it looks like retired revisions where sold to the surplus electronics company.

Re: monster moto shield VNH2SP30 and matlab

It will not run with only D7 and D8 being used Other signals are needed to enable the IC's. I can't say exactly all that will be needed. As I have no experience with the IC's or the board. Just what the schematic and data sheet provided. The enable, PWM determines speed. INA, INB determine which dir...

Re: monster moto shield VNH2SP30 and matlab

Are you inputting the other signals that maybe needed to run the motor or are you expecting D7 and D8 signals alone will run the motor?
Although for Arduino. The example code also shows what other signals are used.

Re: Multimeter

Check your manual and see what the one line or two line markings mean.
If you have the meter set to measure AC. The DC voltage from a battery will read close to .001 volts.
If you are on the DC range. Check your manual. See if it may have a protective fuse in it. That maybe open.

Re: battery

Exactly what are you using to charge the battery?
Sparkfun does have a few charging boards listed on their sales site.
By chance are you using one of their USB to Lithium Battery charging boards? What it the part number if you are using one?

Re: battery

Did you see the charging warning on the batteries sales page. It requires a charger specially made for that type of battery. "These batteries require special charging. Do not attempt to charge these with anything but a specialized LiPo charger." I suspect its protective circuit is not allowing your ...

Re: Si470x breakout on 5V

I would say no.
Look at the data sheet again. VD and VA can be 5 volts. The VIO voltage is rated 1.5 to 3.6 volts.
The schematic shows VD,VA and VIO are all on one voltage input connection.

Re: What is Resistor and Its Function?

More information will be needed. It really depends on how the resistor is used. If it was the heating elements resistance and it is open. The thing is dead. If it was used in series with the heating element to lower the current into the element to lower its temperature. If it was in an electronic co...

Re: Rotary encoder on a motor

Do you have the encoders full model number?
The link you posted. Shows many options. Like pulses per revolution, operating voltage and output type. There is a chart on the page and downloadable manual to look at.

Re: BLE Mate 2 pairing

The sales page says Bluetooth 4.0 and will not connect with older devices. It also does not support the older Bluetooth Serial Port Protocol.
Maybe that has something to do with it.
