Had a fun evening making a basic object avoidance robot.
Using an Arduino Nano (compatible) and a HC-SR04 ultra-sonic distance sensor.
Buried in there somewhere is an L298N dual h-bridge to control the motors.
I played with the ultra sonic sensor over 2 years ago (http://winkleink.blogspot.co.uk/2012/05/arduino-hc-sr04-ultrasonic-distance.html) and haven't used it since.
The motor deck/robot was only 6 months ago the last time I did anything with it (http://winkleink.blogspot.co.uk/2014/02/arduino-compatible-robot-for-15.html). That time I had it wired up to a Pro Mini. If you're comfortable with using a serial adapter to program a breadboard friendly Arduino type device these are great and really cheap. From Hong Kong they are less than £2.00. Important is to make sure your USB/Serial programmer has the DTR line as this is needed to reset the Arduino so it can go into programming mode. Regular Reset needs some effort to get it to work so just easier to get a USB to UART with DTR exposed.
If you look carefully at the picture you'll see the Nano is over hanging the breadboard. This is because the breadboard is only 170 tie and there wasn't enough ties left for the ultra sonic sensor. Not a big deal as obviously none of the pins not in the breadboard are needed.
I'm doing this to prepare for a computer club I'm running in the New Year at my kids school and this time this deck/Arduino will be the focus. (http://winkleink.blogspot.co.uk/2014/11/preparing-for-2015-after-school.html)
Good fun. Now I need to code it to be controlled by an Infra-red remote. Then do a line line following version as well. The kids over 10 weeks will do all 3 projects and depending on how they get on there are a few more that I've thought up based on this configuration.
Wires a bit mad, but all connected OK.
I’ve been considering the idea of migrating customer systems from on-premise Windows Server 2003 SBS to Windows Server 2012 r2 Essentials hosted on Azure for a while now. For one reason or another I’ve stuck to on-premises deployments, mainly due to lack…
I couldn't figure out a way of exporting the video in high-def while maintaining the slo-mo though.
Used about 5gb of storage on my iPhone yesterday, thank god I went for the 128gb model!
Google plus is for sure the right place for your Apply nay-saying, loads of people on here that can't afford a decent phone either.
