The input(IN2) pin of the motor driver is connected to the digital Write pin(P3) of the Arduino. The input(IN1) pin of the motor driver is connected to the digital Write pin(P2) of the Arduino. The black wire(Negative terminal) of the Lipo battery is connected to the input of the L298n Motor Driver.Įnable(ENA) pin of the motor driver is connected to the digital write pin(P6) of the Arduino. The red wire(positive terminal) of the Lipo battery is connected to the input of the L298n Motor Driver. And if the motor requires to be run at half speed, then you will set the value 511 or 512 - half of the maximum value that will cause the motor to be running at half speed. Similarly, setting the value as '0' will be sending no signal and the motor won't start.

the maximum value it can handle that will ultimately run the motor at full speed. The output voltage on that pin is 2.475V.Įxample: If you intend to run the motor at full speed, you will set the value 1023 i.e. The output voltage on that pin is 0.825V.įor a 75% duty cycle, it would be generated with analogWrite(767). The output voltage on that pin is 1.65 volt.įor a 25% duty cycle, it would be generated with analogWrite(255). The output voltage for 50% duty cycle = 3.3 volt * 50 = 1.65 volt Duty cycle = (Active Time of the signal)/(Time-period).Įxample: Set the LED to blink 1 second for ON and 1 second for OFF.ĭuty Cycle (in percentage) = ( ON Time/Total Time period)*100 Repeat the toggling for some more time and you will observe that the speed keeps decreasing with the increase in toggle and this is the main objective of 'PWM'.ĭuty-cycle: The duty cycle is described as the amount of time the signal switches between ON and OFF conditions. Now switch on the fan again, but this time you try to toggle the switch between on and off quickly for some time, now we will observe some reduction in the speed of the fan. After some time the fan attains a constant speed and now switches off the fan and lets it come to rest. This is done by analog_write block.Įxample: When you enter a room and switch on the fan for some time. It is possible to control the brightness of the LEDs or speed of a motor, by switching the given voltage ON and OFF very fast and controlling how long it is ON and how long it is OFF. Generating an analog signal using a digital source. PWM Signal: Controlling the speed of the motorĪ Pulse Width Modulation (PWM) Signal is a method for

Transistors or MOSFET switch the motor at the center forming an H-like configuration.īy activating two particular switches at the same time we can change the direction of the current flow, thus change the rotation direction of the motor. H-bridge circuit: Controlling direction(Forward and Backward)įor controlling the rotation direction, we just need to inverse the direction of the current flow through the motor, this method can be done by H bridge circuit.Ģ. The module can drive DC motors that have voltages between 5 and 35V, with a peak current up to 2A. we can even send data to computer or App, so your customer can read the data on time.The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. Our BMS can monitor many more factors such as temperature, humidity,etc. In case battery cell are already charged full, the BMS will shut down the power flow, in case there is no BMS, the already filled charged battery cell will go on with the charging and thus will short its life or even cause heat or fire. and it will stop charging when the desired voltage is reached.įor example, in 10 cells pack, some battery cell may reach its full capacity already, while others might only 80% full. A BMS is a simple electronics system to measure and control voltage and current. Battery Management System (usually short for BMS), which is an electronic regulator that mainly designed to monitor and control the charging and discharging voltage and current of lithium battery cells or other rechargeable cells.įor Battery packs that contain too many battery cells, since battery cells voltage and capacity are not performing the same all the time, that’s why BMS comes out.
