A small project of temperature controlled heater pads using ATMega microcontroller and relays.
This project is a simple example of DC motor control circuit using L293D driver. The main control board is UNO R3 with ATMega328P microcontroller. It is used to read data from water sensor and pass signals to L293D controller.
If you own LG 27GL850 and experience flickering issues while using integrated GPU on any frequency except 120Hz, you came to the right place.
Your laptop might develop overheating and / or noise issues over time. It could very well have these problems from the start (gaming laptops). You can very easily get the temperatures down by 5-8° by repasting the CPU and GPU.
