No datasheet link so I measured the forward voltage of each: Red = 1.7 V, Orange = 1.7 V, Yellow = 1.8 V, Green = 1.8 V, Blue = 2.5 V, Purple = 3 V.
I just uploaded a video of this robot walking, I control it via WiFi with arrow keys on keyboard.
Why no quantity price breaks? :(
Am I the first one to notice this... the JST polarity is the wrong way round!
I don’t think this is being too picky. I was actually confused by “a rate of 500mA per hour”, I assumed it meant that the current drops by 500mA per hour as some kind of safety feature.
Found the problem. The Arduino was sending strings to the RFID instead of bytes. Need to change rfid.print(number) to rfid.write((uint8_t)number) in functions: halt() and seek(). Works great now!
I uploaded working code to: https://github.com/SebMadgwick/RFID_Eval_13_56MHz
Sparkfun must be the coolest company I know but if I saw you guys dancing like that, for this meme, I would defiantly lose some respect for you guys.
I did this and I get the "START" message but that's it. The "Found" and "Search" LEDs don't do anything and nothing new appears more on the serial terminal. I testing it with the tag SEN-10128 but have also tried various cards in my wallet.
Any idea what's going wrong?
I like the black JST, do you have a part# for that?
I just powered my up and it appeared as a keyboard. I sent the "S~,0" command to revert to SPP and it now appears as "Other". This would seem to indicate it has HID firmware installed and that HID mode is default.
