Study Notes
Breadboards and Components
- Breadboards allow for easy construction and testing of electronic circuits without soldering.
- An LED (light-emitting diode) glows when a voltage is applied to it, indicating the flow of current.
- Resistance in electrical components is measured in ohms (Ω) using a multimeter.
Thermistors and Sensors
- A thermistor's resistance varies significantly with temperature, making it useful for temperature sensing.
- A photoresistor (or LDR - light-dependent resistor) changes its resistance based on light exposure.
Varistors and Resistors
- A varistor's resistance varies with the voltage applied across it, providing protection against voltage spikes.
- Surface-mount resistors are space-efficient components that save space on printed circuit boards.
Jumper Wires and Photocells
- Jumper wires are used to make connections between different components in a circuit.
- A photocell decreases its resistance when light shines on it, allowing more current to flow.
Arduino UNO Board Functions and Memory
- Jumper wires colored brown typically indicate a connection to Ground (GND).
- Red jumper wires are usually connected to a source of power, such as voltage supply.
- 'TX' stands for transmit on an Arduino UNO board, used for serial communication.
- The microcontroller (Atmega328P) fetches program instructions from the flash memory on an Arduino board.
Value Ranges and Programming
- An analog quantity can take any value between its minimum and maximum limits.
- 'RX' on an Arduino UNO board stands for receive, also related to serial communication.
- Arduino IDE uses a simplified version of C/C++ programming language, making it accessible for users.
- The Atmega328P in an Arduino board has 32 kilobytes of flash memory for storing programs.
- Analog pins on an Arduino UNO board are labeled A0 to A5 for input of varying voltage levels.
- The CPU controls operations in an Arduino board, supported by SRAM (static random-access memory) for processing and temporary storage.
