Customer #405641 on BOB-10616 - TLC5940 Breakout

Can I use one of these with a raspberry pi to control an electronic speed controller, ESC, for outrunner brushless motors? Sorry I don’t have a lot of experience with electronics but it would seem that...

Customer #440983 on SEN-09405 - LPG Gas Sensor - MQ-6

The distance measured is probably 0 units of measurement from the interior of the sensor! It does not use radiated or reflected spectral analysis. The wind screen is a good indicator that it needs...

LarryV on LCD-09352 - Graphic LCD Serial Backpack

Does anyone know what the required code changes are to use the code at (http://serialglcd.sourceforge.net/) for use with the 160x128. Is it just the hard coded display size or is driving the 160x128...

MikeGrusin on COM-11323 - EL Sequencer

OK, I’ll try to clarify things. There is one hardware serial port on the Arduino built into the EL Sequencer, and that single port is connected to both the XBee and the FTDI header. You can use either...

Customer #412170 on DEV-11851 - LCD Button Shield

Is this shield compatible with the official Arduino Wi-Fi shield? I’m not sure if they’ll work fine together because of pins 10 and 7… (Arduino UNO)

You do realize that the problem then becomes who’s coin to use? Or maybe we should take multiple photos with multiple world coins and just show you yours based on your location? (IT get on that! ;)But...

Customer #312998 on PGM-11460 - Tiny AVR Programmer

The computer being used is a Dell Vostro desktop, I think that the problem is one of insufficient power being outsourced from the USB port. If a USB 3 port is used then the programmer does not start to...

NAND is not the same as XOR. You can create a XOR with a few NANDs though.

Customer #405641 on SEN-11486 - 9 Degrees of Freedom - MPU-9150 Breakout

Yep mine did as well. You need to multiply and add offsets to the values to get a sphere. I have an old spreadsheet that ran a regression to get the offsets and factors..

liudr on DEV-11851 - LCD Button Shield

I wouldn’t bother. Arduino wifi shield has an antenna made of copper trace on the board, which is pretty weak. I don’t want to put anything above it. To answer your question, no pin 7 is used on both...

To drive this off a 5V Arduino pin, what resistor should I use? Thanks!

Customer #355602 on According to Pete - Analog to Digital Conversion

Pete, you had it right the first time it’s 1023 (i.e. 1111111111) not 1024! Common mistake.

Customer #414061 on LCD-09394 - Serial Enabled 16x2 LCD - Red on Black 5V

Just a helpful note to anyone who might run into this later: I connected the serial lcd to my arduino and wrote a sketch to cycle through the brightness settings on the backlight. Somehow in my...

Kamiquasi on COM-09469 - LED - Infrared 850nm

If you don’t mind running it at 20mA, then the usual calculations apply: R = (Vsupply – Vf) / If: R = (5V – 1.5V) / 0.02 = 175 Ohm. Nearest R12 series: 180 Ohm.The reason I mention the 20mA is because...

Customer #427317 on SEN-11234 - MPU-6000

Too bad it’s going to take that long. I’d be interested in making my own, but the overhead of SMD is kinda heavy. What is the difference between this MPU6050.

Kamiquasi on SEN-11234 - MPU-6000

The New Product Friday post from 2013/May/24 happened to mention:The MPU-6000 is similar to the MPU-6050, but the 6000 has both I2C as well as SPI (the MPU-6050 only has I2C).

bladE_666 on BOB-10160 - DeadOn RTC - DS3234 Breakout

Dunno, but regarding to my earlier post, accuracy seems to be pretty good in long term scale. It may fluctuate more than 2 ppm on a single day, but overall stability seems to be far more better instead...

JohnGalt on LCD-11743 - Raspberry Pi Display Module - 3.2" Touchscreen LCD

Could Sparkfun offer a real live honest to goodness touchscreen only for the RPi (DSI based) rather than this 4d systems visi-genie crap. I can understand it for the arduino platform…. but the RPi is a...
