How to use ULN2003apg

I want to control a 30x1 array of pins through a raspberry pi B+. On a breadboard, I set up a series of shift registers (74HC595) to an array of 2V leds, which I can control as intended. After the leds, I'd like to increase the current from 4mA to 25mA. I installed a series of darlington transistor ...

Is it possible to establish communication between the device and the Arduino with RS232 interface

I have a device that is powered by the Arduino (+5V). https://i.stack.imgur.com/Z0423.png The device (a VC0706 Powered camera), incomporates a MAX3232 to convert to RS-232. Unfortunatly, I don't have the tools or dexterity to remove the TTL/RS232 conversion manually. My question is: is it possible t...

STM32 communicating with LCD module HY28B

Hello, I'm currently in trouble with displaying something on the HY28B LCD module . I configured my LCD module in 16bits mode by soldering the right short at the right place and I'm using an STM32 discovery board STM32 discovery board to drive the LCD module. I ported the source code given by the se...
