Hi, I'm fairly new to microcontrollers and have read multiple guides, although still asking the question. I have used Arduino for quite a long time and have developed some product concept. I am only 14 years old though. I am currently developing a wearable project, therefore size, weight, and battery are huge constraints. My project will include; Touch OLED, Gyro, IR LED and receiver. As I have used Arduino, I am quite familiar with the Arduino offset of C++. It will be appreciated if the MCU has example codes/ others have used similar components. Could you please help me on both; hardware and software. Thankyou in advance.
I need a simple IR extender; it's for just a few feet, but it would make watching TV better. I have a blaster (from an old TV); it has several feet of wire attached, which will be plenty. I'm hoping to use it for this project. I found this project: http://www.electronics-lab.com/project/ir-remote-extender/ Is this the simplest that such a project can be? That is, could I get an IR sensor and the appropriate PS for it and the blaster, and then feed the sensor's out to the blaster's in? Or, does the signal have to be demodulated? If so, could I just use a TSOP1738 (or similar), and feed it into the blaster (perhaps with some extra components, like Q2)? So, why does that circuit need a 555?
