I have a Blackberry Keypad, and a custom Gamepad. I am trying to make them into bluetooth HID(s). They will be part of a single physical unit/board. I need help to get those inputs into a bluetooth chip and transmitted accurately in real-time. (The...
The bi-color matrices I ordered turned out to be common-anode ones, and not common-cathode as I expected. This means that I can't drive them with the HT16K33 chip as I planned, as it only has 8 cathode pins. I can't even use two such chips to drive the...
2 years ago when I started my hexapod, I didn't have to much cash to spend, so i bought 12 of these https://hobbyking.com/en_us/turnigytm-tgy-s901d-ds-mg-robot-servo-13kg-0-14sec-58g.html from hobbyking. When I got them, one broke in a year,...
I'm on my wit's end, so I thought maybe I will ask for help here. I'm trying to get to work an ILI9340-based LCD display. One of the cheap ones, not the ones from Adafruit. It looks like this:I tried to use both the ILI9340...
I'm thinking of re-doing the electronics to an old shift-register based 8x8x8 LED cube (uses 5v LEDs). I want to instead do fast pwm in hardware.Unfortunately its built with the layers being common anode. So I need 64 individual pwm outputs which...
I have built a circuit that doesn't work. (This is not unusual for me.) The circuit uses relays to count pulses from an old rotary phone dial... or is supposed to. I'm using a combination of the following circuits from http://www.electronixandmore.com/projects/relaycomputertwo/index.html (their...
I'm not going to mention the brand incase there's any issues with that but a friend recently gave me a beat to hell electric longboard without the charger or controller. I'm not too worried about the charger since I'm probably going to open up the batteries...
I never check my arduino.cc account, and so I forgot my password. I'm usually on here, so i'll lay some error code here and if anyone can make sense of it, that would be great. On my project #12 Servo Hexapod , i'm 90% sure it's my mega that's screwing...
