Electric bike controller 24v. Basic Info.

Generic controller 250W 24V. 36V to repair any ebikes and mini scooter

Working with or without a handlebar housing, this controller can repair most electric bicycles of Asian origin, equipped with a brushless motor.

Dual sensored / sensorless it works with or without Hall sensors motors.

These controllers will allow you to repair at a good price any electric assisted bike equipped with a 250W brushless wheel motor. These controllers work in sensorless and sensored mode which will allow you to operate a motor which would have a problem of Hall sensors (sensor HS or wire cut). To simplify installation, we suggest using only the sensorless mode (only 3 wires to connect instead of 8). These controllers can be used only with an accelerator or only with a foot switch or with both systems in parallel.

Controller Wiring

For those who wish to use only the accelerator, it will not be necessary to take the handlebar box separately to be able to turn the system on and off at the handlebars or to have an autonomy gauge.

For those who want to use a bottom bracket sensor, we suggest you take a V7 bottom bracket sensor and the management box on the handlebars.

For the less handymen among you, we advise you to take the controller with an accelerator only.

With the generic controller, we provide different adapters for easy installation. This avoids cutting the plugs of the controller.

The shunt allows the controller to be used without a screen. It is installed in place of it.

L298N Driver

The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. The module can drive DC motors that have voltages between 5 and 35V, with a peak current up to 2A.

Let’s take a closer look at the pinout of L298N module and explain how it works. The module has two screw terminal blocks for the motor A and B, and another screw terminal block for the Ground pin, the VCC for motor and a 5V pin which can either be an input or output.

This depends on the voltage used at the motors VCC. The module have an onboard 5V regulator which is either enabled or disabled using a jumper. If the motor supply voltage is up to 12V we can enable the 5V regulator and the 5V pin can be used as output, for example for powering our Arduino board. But if the motor voltage is greater than 12V we must disconnect the jumper because those voltages will cause damage to the onboard 5V regulator. In this case the 5V pin will be used as input as we need connect it to a 5V power supply in order the IC to work properly.

We can note here that this IC makes a voltage drop of about 2V. So for example, if we use a 12V power supply, the voltage at motors terminals will be about 10V, which means that we won’t be able to get the maximum speed out of our 12V DC motor.

Next are the logic control inputs. The Enable A and Enable B pins are used for enabling and controlling the speed of the motor. If a jumper is present on this pin, the motor will be enabled and work at maximum speed, and if we remove the jumper we can connect a PWM input to this pin and in that way control the speed of the motor. If we connect this pin to a Ground the motor will be disabled.

Next, the Input 1 and Input 2 pins are used for controlling the rotation direction of the motor A, and the inputs 3 and 4 for the motor B. Using these pins we actually control the switches of the H-Bridge inside the L298N IC. If input 1 is LOW and input 2 is HIGH the motor will move forward, and vice versa, if input 1 is HIGH and input 2 is LOW the motor will move backward. In case both inputs are same, either LOW or HIGH the motor will stop. The same applies for the inputs 3 and 4 and the motor B.

Arduino and L298N Motor Driver

Now let’s make some practical applications. In the first example we will control the speed of the motor using a potentiometer and change the rotation direction using a push button. Here’s the circuit schematics.

So we need an L298N motor driver, a DC motor, a potentiometer, a push button and an Arduino board.

Arduino Code

/ Arduino DC Motor Control. PWM | H-Bridge | L298N. Example 01 by Dejan Nedelkovski, www.HowToMechatronics.com / #define enA 9 #define in1 6 #define in2 7 #define button 4 int rotDirection = 0; int pressed = false; void setup pinMode(enA, OUTPUT); pinMode(in1, OUTPUT); pinMode(in2, OUTPUT); pinMode(button, INPUT); // Set initial rotation direction digitalWrite(in1, LOW); digitalWrite(in2, HIGH); void loop int potValue = analogRead(A0); // Read potentiometer value int pwmOutput = map(potValue, 0, 1023, 0. 255); // Map the potentiometer value from 0 to 255 analogWrite(enA, pwmOutput); // Send PWM signal to L298N Enable pin // Read button. Debounce if (digitalRead(button) true) pressed = !pressed; while (digitalRead(button) true); delay(20); // If button is pressed. change rotation direction if (pressed true rotDirection 0) digitalWrite(in1, HIGH); digitalWrite(in2, LOW); rotDirection = 1; delay(20); // If button is pressed. change rotation direction if (pressed false rotDirection 1) digitalWrite(in1, LOW); digitalWrite(in2, HIGH); rotDirection = 0; delay(20); Code language: Arduino (arduino)

Description: So first we need to define the pins and some variables needed for the program. In the setup section we need to set the pin modes and the initial rotation direction of the motor. In the loop section we start by reading the potentiometer value and then map the value that we get from it which is from 0 to 1023, to a value from 0 to 255 for the PWM signal, or that’s 0 to 100% duty cycle of the PWM signal. Then using the analogWrite function we send the PWM signal to the Enable pin of the L298N board, which actually drives the motor.

Next, we check whether we have pressed the button, and if that’s true, we will change the rotation direction of the motor by setting the Input 1 and Input 2 states inversely. The push button will work as toggle button and each time we press it, it will change the rotation direction of the motor.

Arduino Robot Car Control using L298N Motor Driver

So once we have learned this, now we can build our own Arduino robot car. Here’s the circuit schematic:

All we need is 2 DC Motors, the L298N motor driver, an Arduino board and a joystick for the control. As for the power supply, I chose to use three 3.7V Li-ion batteries, providing total of 11V. I made the chassis out of 3 mm tick plywood, attached the motors to it using metal brackets, attached wheels to the motors and in front attached a swivel wheel.

Now let’s take a look at the Arduino code and see how it works. (Down below you can find the complete code)

int xAxis = analogRead(A0); // Read Joysticks X-axis int yAxis = analogRead(A1); // Read Joysticks Y-axisCode language: Arduino (arduino)

After defining the pins, in the loop section, we start with reading the joystick X and Y axis values. The joystick is actually made of two potentiometers which are connected to the analog inputs of the Arduino and they have values from 0 to 1023. When the joystick stays in its center position the value of both potentiometers, or axes is around 512.

We will add a little tolerance and consider the values from 470 to 550 as center. So if we move the Y axis of joystick backward and the value goes below 470 we will set the two motors rotation direction to backward using the four input pins. Then, we will convert the declining values from 470 to 0 into increasing PWM values from 0 to 255 which is actually the speed of the motor.

// Y-axis used for forward and backward control if (yAxis 470) // Set Motor A backward digitalWrite(in1, HIGH); digitalWrite(in2, LOW); // Set Motor B backward digitalWrite(in3, HIGH); digitalWrite(in4, LOW); // Convert the declining Y-axis readings for going backward from 470 to 0 into 0 to 255 value for the PWM signal for increasing the motor speed motorSpeedA = map(yAxis, 470, 0, 0, 255); motorSpeedB = map(yAxis, 470, 0, 0, 255); Code language: Arduino (arduino)

Similar, if we move the Y axis of the joystick forward and the value goes above 550 we will set the motors to move forward and convert the readings from 550 to 1023 into PWM values from 0 to 255. If the joystick stays in its center the motors speed will be zero.

Next, let’s see how we use the X axis for the left and right control of the car.

// X-axis used for left and right control if (xAxis 470) // Convert the declining X-axis readings from 470 to 0 into increasing 0 to 255 value int xMapped = map(xAxis, 470, 0, 0, 255); // Move to left. decrease left motor speed, increase right motor speed motorSpeedA = motorSpeedA. xMapped; motorSpeedB = motorSpeedB xMapped; // Confine the range from 0 to 255 if (motorSpeedA 0) motorSpeedA = 0; if (motorSpeedB 255) motorSpeedB = 255; Code language: Arduino (arduino)

So again, first we need to convert the X axis readings into speed values from 0 to 255. For moving left, we use this value to decrease the left motor speed and increase the right motor speed. Here, because of the arithmetic functions we use two additional “if” statements to confine the range of the motor speed from 0 to 255.
