DIY / IoT electronics for students and hobbyists

I got stuff from my days in university, they’re all in working condition, and I don’t have time to use them anymore… What I got: - arduino mega 2560 -> $5 - arduino mega 2560 -> $5 - arduino mega 2560 -> $5 - arduino mega 2560 -> $5 - 2x breadboards -> $5 - 2x breadboards -> $5 - 2x breadboards -> $5 - 2x breadboards -> $5 - 2x breadboards -> $5 - 2x micro serve sg90 -> $5 - 2x micro serve sg90 -> $5 - 2x micro serve sg90 -> $5 - 2x micro serve sg90 -> $5 - 2x micro serve sg90 -> $5 - 2x micro serve sg90 -> $5 - 2x micro serve sg90 -> $5 - arduino uno -> $5 - arduino relay x4 hat (one hat, 4 relays) -> $5 - 2x 5vdc fans for arduino / raspberry pi -> $5 - 2x 12vdc fans for 3D printer mods -> $5 - 2x ultrasound sensors HC-SR04 -> $5 - 2x ultrasound sensors HC-SR04 -> $5 - 2x ultrasound sensors HC-SR04 -> $5 - 2x ultrasound sensors HC-SR04 -> $5 - 2x ultrasound sensors HC-SR04 -> $5 - 2x ultrasound sensors HC-SR04 -> $5 - Arduino xbee hat for sd and micro sd card -> $5 - 12x linear bearings for 3D printer mods -> $10 - tons of 10 wire and 6 wire ribbon cable -> $5 for both - Arduino lilipad -> $5 - Texas Instruments MSP EXP430G2 -> $5 - Arduino 3.5” tft r61581 -> $10 - Arduino 3.5” tft r61581 -> $10 - Arduino 3.5” tft r61581 -> $10 - Arduino 3.5” tft r61581 -> $10 - Adafruit Power relay feather wing hat -> $10 - 3x 5V DC motors -> $5 - Relay module for 4 relays -> $5 - L6470 AutoDriver (sparkfun) stepper driver for up to 24V-> $10 - L6470 AutoDriver (sparkfun) stepper driver for up to 24V-> $10 - L6470 AutoDriver (sparkfun) stepper driver for up to 24V-> $10 - L6470 AutoDriver (sparkfun) stepper driver for up to 24V-> $10 - 3x surface mount esp 8266 chips -> $5 - Arduino Ethernet hat -> $5 - 4x humidity sensors for plants -> $5 As mentioned all are working, in most cases unused. I’ll add in bonus stuff if you get multiples I also have actual components / chips like SMT LEDs and Arduino chips
