Circuits, Third Edition Textbook helps students understand a wide range of timeless principles and problem techniques that are essential to circuit studies. Generally, circuit theory is the entry course in pursuing education in electrical and computer engineering. While this book is a great introductory text, a background in physics and elementary differential and integral calculus is assumed.

The PmodTMP2 is an ambient temperature sensor powered by the Analog Devices® ADT7420. Through the I2C interface, users may appreciate a resolution of 0.0078 °C through 16 bits of data.

Features:

• Uses the Analog Devices® ADT7420
• Up to 16-bit resolution
• Typical accuracy better than 0.25 °C
• I2C interface with 4 selectable addresses
• 240ms continuous conversion time
• Programmable overtemperature/undertemperature control pins
• No calibration required

The PmodSWT provides users with four slides switches for up to 16 different binary logic inputs to for the attached system board.

Features:

• 4 slide switches
• Add user input to host board or project
• Static binary logic input
• Small PCB size for flexible designs 1.3 in × 0.8 in (3.3 cm × 2.0 cm)
• 6-pin Pmod connector with GPIO interface
• Follows Digilent Pmod Interface Specification Type 1

The PmodSSD is a two-digit seven-segment display. Users can toggle through GPIO signals which digit is currently on at a rate of 50 Hz or greater to achieve persistence-of-vision to give the effect of both digits being lit up simultaneously.

The PmodMAXSONAR is a single-transducer ultrasonic range finder that uses the MaxBotix® LV-MaxSonar®-EZ1™. Users can measure how far away an object is with an accuracy within 1 inch to over 20 feet away. Information is sent in a variety of ways including UART, PWM, and analog signals.

Features:

• Ultrasonic range finder with effective detection range of 6 in - 255 in (15 cm - 648 cm)
• Detect object distance with 1.0 in (2.54 cm) resolution up to 20 ft away
• Continuous measurement (free run) operation
• Three options for sending range data: UART, analog and PWM
• Small PCB size for flexible designs 0.9 in × 0.8 in (2.3 cm × 2.0 cm)
• 6-pin Pmod connector with UART interface

PmodKYPD - 16-Button Keypad is a peripheral module featuring a 16-button keypad. The keys are numbered in a hexadecimal fashion (0-9, A-F). It uses a standard 12-pin Pmod header that will indicate which row and which column has been pressed in the array of buttons.

The PmodACL2 is a 3-axis MEMS accelerometer powered by the Analog Devices ADXL362. By communicating with the chip via the SPI protocol, users may receive up to 12 bits of resolution for each axis of acceleration.

Features:

• Based on the Analog Devices ADXL362 3-Axis MEMS Accelerometer
• Communicates via SPI
• User selectable resolution
• Less than 2 μA of current consumption at 100 Hz output data rate
• Single or double-tap detection capability
• Free-fall detection
