Years ago I spent some time analyzing Candle-Flicker LEDs that contain an integrated circuit to mimic the flickering nature of real candles. Artificial candles have evolved quite a bit since then, …
Wow so many clueless people here seeing mcu and immediately thinking “remotely hackable device”. First of all, micro processors are used in all but the cheapest of your household electronics. They’re a cheap way of reducing the hardware design requirements for devices by replacing them with a bit of software.
Second, these devices don’t have or want a way to remotely connect to them. They don’t send or receive any wireless signals.
I don’t think people realize how common PIC12 uCs (and clones) are these days. A huge chunk of PIC12 uCs are OTP as well, so no one can ever change the code once its been written to. Its more cost-efficient to build one-time-programmable microcontrollers than to try to change an ASIC production line over-and-over for each different product line.
