Arduino Tut#16 – DC Motor Drives, Voltage, Direction, H-Bridge, PWM

By | 2016-09-23T22:44:32+00:00 May 4th, 2015|Arduino, Tutorials|

DC Motor Drives - Voltage, Frequency, PWM, H-Bridges and more... DC Motors are inexpensive, small and can be ran from very low voltages through a Motor Drive. This makes them attractive options for makers who are interested in robotics. You can run a DC motor by supplying a voltage difference across its leads. However, you [...]

Use 4 Arduino pins for 16 outputs! Serial to Parallel Demultiplexer

By | 2016-09-23T22:45:38+00:00 March 25th, 2015|Arduino, Tutorials|

Arduino Serial to Parallel Demultiplexer A demultiplexer is a great way to allow you to use more output pins for your Arduino. Its purpose is to take a Serial signal and convert it to a parallel one. This functionality is extremely simple to implement and can be a great alternative to shift registers discussed in [...]

Electronics #2 – MOSFET sizing challenges and considerations

By | 2016-06-24T20:07:28+00:00 March 3rd, 2015|Blog|

MOSFET sizing dilema I had to deal with an issue revolving around MOSFET sizing; hence today's video. The fact of the matter is that sizing a transistor should be one of the fundamentals an electrical engineer should know, but many struggle with the concept. Remember to ALWAYS read your datasheets and breadboard the circuit before [...]
