Thank you! 😃

Thank you for your feedback!

The code supports only up to 10 bits. However, you can edit the code to input a 14-bit value. For this, you should change the number of iterations in the for loops that are setting the pin mode and reading the binary value. By doing this, you can achieve your requirement. Also, note that since you will be using pins 0 and 1, you need to disconnect everything from these pins while uploading the code.

Resistors aur battery ki value check karye. Agar isme koi change hai to LED theek se respond nhi karega.

Hi, sorry for the delayed response. This is a common issue that occurs with some circuits such as NOT Gate using transistors. This problem might be because when the NOT gate is activated, it’s drawing too much current from the power supply, leaving insufficient power for other components. A possible solution is you could use a current limiting resistor. This resistor can be added to your circuit to limit the amount of current going into your NOT gate. Let me know if this solution works.

@@electronics_champ Thanks! I will try that solution.

Hi, you can change the distance between the sensors. You must also update the distance variable in the code. By default, it is set to 1 (metre). Ensure that you set it in metres and not any other units.

Link to the code is given in the description

You can find that out using Ohm’s Law, which is V = I * R. V is volts, I is amps, and R is resistance. You already have V (3.3); and a typical LED can handle 20 milliamps, so I is .02; so you want to know the resistor value. R = V/I or R = 3.3/.02 which is 165 ohms. 165 ohms is a reasonable resistor for any LED using a battery up to 9 volts

I would use a 165 ohm resistor (based on Ohm’s Law).

If you want to see the results on the Serial Monitor, just ignore the connections of the OLED display. You can use the same code. If you want to use any other display, the code needs a revision.

I have another problem, the time 1, it comes out very low@@electronics_champ

Audrino model bro?

If you are using Arduino NANO for the transmitter, then you have to first wait for the MPU6050 to calibrate. This will take about 20 seconds. After that, try to tilt the MPU6050 and check what is printed on the Serial Monitor.

@@electronics_champ Thank You sir for replying so quickly. So I have implemented your nrf24L01 latest video for transmitter and reciever so now the reciever is recieving the signal but motor driver is not working now. Please sir help me with the code I am making hand gesture car.

Motor drivers require enough power to drive the motors. If you are getting the correct values on the Serial Monitor of the receiver, then the problem might be with the battery that is used. Let me know the batteries that you are using to run the motor driver.

Sir now it worked really well.

Can you give me some more details about the issue?

If both the Serial Monitors are displaying property but the motors are not moving, the problem might be with the battery that is used to drive the motors. You have to use a lithium or alkaline battery that can drive the motors. Let me know which battery you are currently using.

@@electronics_champ it worked brother .. i had unpinned the speed control of motor driver .. thanks for your help

Glad you liked the video! Please consider subscribing!

The object has to cross both the sensors to calculate the speed. If it does not, nothing will be displayed.

Thank you so much for your kind words! I appreciate your support. Sometimes great content takes a little time to get the recognition it deserves, but with viewers like you, we hope to grow and reach more people in the future. 🌟😊

ive seen that this is because the current at the emitter is the sum of the base and collector currents. one way of fixing this is by putting the load before the transistor, but if i was trying to create multiple gates in series to form a logic circuit then this means that i have to effectively build my circuits backwards? i would like to know if there is a way i can fix this.

it seems to me that you have used a method of putting the load before the transistors which im not criticising as it works perfectly fine for the purpose of this video. but would there be any way to do what i am trying to achieve?

The LED glows because of these 3 reasons: *Leakage Current* : Tiny current can flow even when the transistor is off. *Input High without Vcc* : If A is high without Vcc, it can cause current to flow. *Resistor on Input A* : The 10k ohm resistor on A could allow some current to flow, lighting up the LED. This can be fixed by increasing the 10k resistor to a convenient resistance for your circuit. But it is important to test the changes first.

What is the purpose of the LED and the Buzzer in this project?

The resistors help ensure proper biasing of the transistors and limit the current to prevent damage to the components. For example, the 1K resistor works as a pull-down resistor to create a zero output when one of the inputs is zero.

@@electronics_champ thanks sir

Glad it helped. You can check out my other videos too!

I just checked the code again. You can use the same code by taking out the LEDs. Let me know if there are any errors while compiling for Arduino UNO.

Arduino UNO has less pins and cannot accommodate LEDs and Keypad together. However, you can use Arduino UNO by removing the LEDs and using only the OLED Display and Serial Monitor to view the output. This requires minor changes to the code.

OK,thanks for telling 🙂 So can you please send the edited code I will be very thankful for that. please

I have already made that video. You can check it out here: ua-cam.com/video/bYZcz1698lc/v-deo.html

Thank you

I have one more question that is,can we use arduino uno in place of arduino mega In that decimal to binary converter project ?

And where do you buy these transistors from? I don't know why but I can't seem to find discrete CMOS MOSFETS for a breadboard anywhere.

Hi, you’re correct. The method you mentioned can be used to build an AND Gate. However, this method doesn’t allow the output to be controlled by input from other circuits. If you want to turn on an LED when the output of two other circuits is high, then you’ll need to build the AND Gate using transistors. As for the components, I buy them from an offline store. You can check for them from websites such as Amazon or something like that.

When S and R are 1, Q and Q' are 0. This is an illegal state. The condition that causes both Q and Q' to have the same value is logically invalid and may cause problems in other logic that depends on valid values from these outputs.

Powering everything with a regular 9V battery would not work since the L298N motor driver would draw a lot of current. However, you can try to power everything with an alkaline 9V battery, which performs better in high-drain devices. But also note that the battery would drain very quickly. So it is recommended to use an alkaline 9V battery for the motor driver and another regular 9V battery (or any other power source between 7V - 12V) for the Arduino.

The OR Logic does not work in this case.

When using an NPN transistor as a switch, it is best to use it to pull down current by using a resistor. This is done by connecting the emitter to the lowest potential (GND). This configuration enables the transistor to control the flow of current from the collector to the emitter, thus acting as a switch. Hope this helps!
