The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. Motors are rated at certain voltages and can be damaged if the voltage is applied to heavily or if it is dropped quickly to slow the motor down. Using ST L298N chip can directly drive two 3-30V DC motor, and provides a 5V. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. L298N Dual H Bridge Stepper Motor Controller Module Arduino & Raspberry Pi.
In motors try to imagine the brush as a water wheel and electrons as a the flowing droplets of water. * Pulse Width Modulation is a means in controlling the duration of an electronic pulse. H-Bridge's are typically used in controlling motors speed and direction, but can be used for other projects such as driving the brightness of certain lighting projects such as high powered LED arrays.Īn H-Bridge is a circuit that can drive a current in either polarity and be controlled by *Pulse Width Modulation (PWM). Other Extensions: control of direction indicators, the logic part of the plate to take power interface. Storage temperature: -25 Deg C ~ +130 Deg C Maximum power consumption: 20W (when the temperature T = 75 Deg C) The logical part of the operating current range: 0 ~ 36mA It uses the popular L298 motor driver IC. The logical part of the terminal supply area Vss: +5 V ~ +7 V (can take power within the board +5 V) This L298N Based Motor Driver Module is a high power motor driver perfect for driving DC Motors and Stepper Motors. The L298N driver module, using ST's L298N chip can directly drive two 3-30V DC motor, and provides a 5V output interface can 5V single-chip circuitry to supply, support 3.3VMCU control, you can easily control the DC motor speed and direction, you can also control the 2-phase stepper motor, smart car essential.ĭriver: L298N Dual H Bridge DC Motor Driver ICĭriven part of the terminal supply area Vs: +5 V ~ +35 V such as the need to take power within the board, the supply area Vs: +7 V ~ +35 V
