First time here.
I have the Elegoo Most Complete Starter Kit with the Arduino Mega. I went through the PDF it came with and did all of those. But I want to actually make something now with the components included in the box.
I have a 3D printer, and I have some cardboard if i wanted to make anything to go with my circuits.
I am dead broke so I don't have any money to buy extra parts I was hoping to use just what I have in the most complete kit with the Arduino Mega and other sorts and maybe even what i can 3D print or what I scrounge around the house.
Any suggestions would be greatly appreciated thank you all very much
You could 3D print a bracket for the ultrasonic sensor, to mount the sensor on the servo motor: then you can do the radar project. Add the LCD screen into the equation and display a message when something is sensed.
The OLED can be used to tell when the next train will arrive.
The RTC could show on the OLED the time.
The DHT could show the "weather on the OLED.
The LEDs can be used to tell cars, people and trains when to stop, go, proceed with caution.
The resistors could be used for multiple pushbuttons on one pin (voltage divider)
The transistors could power more LEDs... in the windows of model buildings
The servo motor could open and close a gate.
The PIR could sense when you are around to flash a warning light/LED
... you get the drift... make a whole city.
