I use the pressure sensor to control two LEDs.
My circuit chart for series connection, parallel connection, and transistor connection with LED.
This week is the flashlight assignment which I start from connecting several LEDs with 9v battery and resistors. Then tried to use button and potentiometer to turn on and off of led lights. Attached are circuits and photo for these explorations.
These are the circuit schematics I drew for flashlights3, 5, 7. This really helped me the understand how currents & voltage work.
