TF2 Sentry Gun - Scans and Beeps
Description
Here's a TF2 level 1 sentry gun that rotates and beeps like in the game! It's intended to be used as a sort of desktop trinket to look at. The sentry gun is motorized using a 28BYJ-48 stepper motor + ULN2003 driver board. The audio is provided using a micro SD card module, a LM386 op-amp, and a 0.5W 8Ω speaker (larger ones can be used). I've also made it so that pushing a button will stop the scanning process dead center so the entire assembly can be unplugged. The entire thing is controlled by an Arduino Nano because this project requires a surprising amount of pins. **You can access the code here** https://github.com/Xavi009/tf2_sentry_gun_code
