An affordable security alarm system utilizing light intensity detection for safeguarding cash boxes and lockers.

looking for a non-standard resistor that you can't find on the shelf? how about combining some of the resistors you have? this tool does it for you!

Single Channel Analog Read Over Digital Pin for Resistor-like Sensors

💡 A circuit that is used to control a room lighting automatically depending on the time of day, whether day or night. It uses an LDR(Light Dependent Resistor) that varies the resistance depending on the enviroment's light intensity, and thus controls the room light

Use the resistive divider to calculate the unknown resistor, and use the average filter to smooth the value.

If you want to build something using a Raspberry Pi, you'll probably use resistors. For this exercise, you need to know two things about them:

Build any resistor from standard E6 resistors
