SMALL, CHEAP AUDIO AMPLIFIER
Basic and cheap circuit. Amplify any kind of sound signal, up to 8 ohms speacker and 1W.
PCB DESIGN - FIRST STEPS INTO DESIGN SPARK
First we will talk a bit about 8 bit registers of the arduinio, ATMEGA328p datasheet and how to find each register. Then we will see the difference between using Arduino functions or directly register control. Finnaly we will set the register of one timer of the arduino to make an interruption at 2KHz. Inside of that interruption we will create a sort of PWM signal using register control.
BASIC H-BRIDGE CIRCUIT
Small circuit to control the spin direction and speed of two DC motors. It works with voltages up top 14 volts and 2 ampers of curent.
