    Arduino Self-Driving Car

    I don't understand this: if (curDist < COLL_DIST) {changePath();} // if forward is blocked change directionmoveForward(); // move forwardShouldn't the moveForward call be in the if statement?. This of course would necessitate some changes to setup() to get thing started.The reason I ask this is that right now moveForward is getting called every single time through the loop instead of just after a change in path, even though the car is already "moving forward". Which means power to the motor is pulsing when the the speedset loop runs. Or am I missing something?Also why do you do speed ramping when you turn? It looks like you just slam the motors forward on one side or the other when the turn finishes but go back to doing the speed ramping once you reenter the loop.Overal...

I really do appreciate it.

    Sous Vide Cooker for Less Than $40

    I know it's been a year but this is not quite correct L means "LIVE" not "Load"The Live side is connected to the fuse and then is available right under the Nuetral post. There is no post on the "LIVE" side because you want to go through the fuse. I can't tell if there is an internal connection to the switch or not. I'm guessing probably not.be cool if the OP came back and indicated what they found.

    Ultimate DIY Breadboard Power Supply

    Using a linear regulator to provide power 1.5V of power from a 12 volt power supply isn't going to be anywhere close to efficient. You end up with a 10.5 volt volt drop across the regulator being burned off as heat. If your circuit uses 1 amp, then your circuit is using 1.5 Watts of power and your power supply is using 10.5 Watts. 7 times more than your circuit and a total of 12 watts of power. When you are burning that much power you are going to need a big heat sink on your 317. At lower currents, it might not be that big a deal but any time you have it set to 1.5 your power supply is going to be using 7 times as much power as your circuit whether it's 100 mW and 0.7 Watts or 1 Watt and 7 Watts.Might want to consider a variable switching regulator. While they are more expensive, ...

  • How To Burn a Bootloader to Clone Arduino Nano 3.0

    A couple issues:1- Nobody had to reverse engineer the Arduino. The wonderful people at Arduino released all the hardware files as open source. Making and selling clones is legal as long as you don't use the Arduino trademark or try to pass it off as an official "Arduino". Those that do are guilty of trademark infringement.More information here: https://blog.arduino.cc/2013/07/10/send-in-the-clo...2 - Your claim that "<Samsung>literally wait for a new iPhone to come on, then buy a few, and very quickly make the same thing or better versions in a different case and for the 3rd of the price..." Is outlandish and slanderous. I can't believe such a claim is allowed to be published here without any evidence to back it up. Apple makes phones, Samsung makes phone...

Is outlandish and slanderous. I can't believe such a claim is allowed to be published here without any evidence to back it up. Apple makes phones, Samsung makes phones. In the past, Samsung has stepped on the toes of Apple but Apple has been found guilty of infringing Samsung as well. The world of copyright, patent, and trademark infringement can be a very muddled place. I'd be very careful about making these types of claims. You could find yourself on the wrong end of a defamation lawsuit with a very big, very powerful company.
