HI Everyone I have been seeing a few folks having troubles with the Raspberry PI B+ with regard to getting it up and running so in co-operation with E14 I have put together this video in the hopes it will show you how straight forward it should be.   I took a brand new PI B+, empty 64GB Micro SD Card and the old Wireless keyboard, mouse and WIFI dongle to use with the new board   The whole process took about 30 minutes to do (That does not remotely cover the time to prep the video of ...
back to the base project The Electronic Referee   OK, so you have done al the samples, used buttons on a breadboard etc. etc. Now you want to interface stuff from the real world into your microcontroller   If you have not watched the previous video, then please do for how to drive BIG loads from you microcontroller using OPTO Isolators. Drive BIG things with added safety. OPTO Isolators   The real world is an evil place for microcontrollers, loads of EMF to mess with you and bl ...
Back to the base project... The Electronic Referee   So if you have not watched the first video, go do that now and then come back to this one, you can find it here Driving BIG loads with your micro controller - no isolation   This video extends what you will have learned from the previous blog and adds an OPTO Isolator into the mix, for added safety and to protect the microcontroller from EMF and other bad things   The OPTO isolator provides over 4KV of isolation and is easily ...
Back to the base project The Electronic Referee So you have done blinky with an LED on the board, Now what   You want to drive a BIG LED like a 12V, 10W variety or something, well how you going to do that, the micro certainly cant do it without help and a Relay will still need a driver   You want to drive a BIG Servo or other motor up to 24V, well how you going to do that, the micro certainly cant do it without help and a Relay will still need a driver   These and many oth ...
