Output Devices
For this week assigmnement we had to :
- My group assignment was
- My individual assignment ws
The group assignment for this week is to:
measure the power consumption of an output device
V=IR This equation represents the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit Current: is the flow of electric charge in a circuit, measured in amperes (A), representing the rate at which charges move through a conductor. Power: is the rate at which energy is transferred or consumed in a circuit, measured in watts (W), indicating how quickly work is done or energy is converted. Resistance: is the property of a material or component that hinders the flow of electric current, measured in ohms (Ω), determining the degree to which the current is impeded in a circuit. Power is the rate at which work is done or energy is transferred, and it is calculated by multiplying the voltage (V) by the current (I) in a circuit. P=VI A motor is a device that converts electrical energy into mechanical motion or power. Motors are inductors because they contain coils of wire that generate a magnetic field when an electric current passes through them, which enables the conversion of electrical energy into mechanical energy for their operation.
Development Board Design¶
This week we had to work with output devices. Like last week, you can extend the capabilities of your microcontroller to the real world. This time not only to observe but to interact with the real world.
Introduction
Output device week i started from simple LED’s and traffic light to then OLED displays ans speakers, All those devices need to get the information what to do and that can be done by some protocol specific for this device, standard communication (I2C, SPI, UART), or just pulse width manipulation.
LCD¶
LCD : (liquid crystal display) is the technology used for displays in notebook and other smaller computers. Like light-emitting diode (LED) and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology. It’s pins are connected to Ground, VCC, Contrast, Register Select, Read/Write, Enable, Data bit 1, Data bit 2, Data bit 3, Data bit 4, Data bit 5, Data bit 6, Data bit 7. LCD Datasheet
