Thanks for the link, very nice website. I am learning Faraday's law and I am trying to link motional emf to his law. I do understand that a squared loop of wire of length l moving with a velocity v into a stationnary magnetic field B will experience a Lorentz force and this force will induce an...
Hi,
I would like to know how to get the potential difference due to a constant local magnetic field acting on a wire moving at a constant speed perpendicular to the field. What is the link between F = q v ∧ B and the actual difference of potential in the circuit ? How to determine the induced...
Hello,
Here is how I finally did it! It works fine. Thanks a lot for your help. I learned a lot about a world that I didn't know about, electronics!
Thank you!

Hello, I used a the set and reset imput of a second JK flip flop to avoid the bouncing of my switch. It is still not working properly. I was wondering if I need a pulse detector at the imput of the clock of the JK flip flop ? What do you think ? Thank you very much,

Hello the switch story is not finished yet. It doesn't work sometimes. I think I am experiencing some switch bounce. Could you recommend me a component to overcome this problem ? What is hysteresis ? Thank you very much Bbruyne
Oh thank you all very much! I will order the NDP6020P today and try it as soon as possible. I am so pleased that forums like this one exist, they are fantastic! Thanks, I learned a lot!

Hello,
On the NDP6020P, I am reading the datasheet and it is saying that the max gate threshold voltage is -1V. Does that mean the the voltage Gate-Source can't be higher than -1V or that it has to be more that -1V to put the PMOS on ? The min max value are confusing me. Thank you very much! Bbruyne
Yes! This is fantastic, so close to understand how it works! Credits to you! Is that PMOS good for my project ?

So do you agree with the final schem ? I am so...
Thank you both, you are fantastic, I am learning so much. So, rbelli1, the PMOS that you recommended me will work with the signal coming from the Q1 output of my FF because the PMOS is specific for logic level gate, is that right ? No need for any transistor or buffer ? I won't need any...
Hello,
Thank you for your help,
What do you mean by low on resistance ? I haven't found any good tutorials on power mosftets, do you recommend any ? What are the resistance on your schem for ? I have drawn a full schem of my project with the PMOS, I used the same resistance as you did without...
Yes you are right, I didn't know that the flip flop output could not drive the chips. Thanks for this! I am new... Is a p-channel power fet similar to a transistor ? What is it exactly ? Thank you very much for your help.

Hello,
Thank you very much for your support, it is fantastic.
I have tried my ic with a led and my momentary push button as a clock and it toggles as expected. I have a schematic here. I decided to add a voltage regulator.
Thanks for your help,

Hello,
I am building a prototype of a balance indicator to prevent farm quadbike to roll on steep hills. I am using an arduino pro mini and 2 sets of assignable strips of 8 leds (https://www.adafruit.com/products/1426) and a gyro-accelerometer sensor. To power it, I am using the farm motor bike...
