Electrical Engineering Jobs

Electrical engineering is a branch of engineering that involves the study of electricity, electromagnetism and electronics. An electrical engineer knows how to deal with a host of electrical appliances and devices. To ensure that your electrical device is compliant with the set standards, you need to hire a professional electrical engineer. For this, all you have to do is hire a professional electrical engineer. Once you have an experienced electrical engineer onboard you can hope to add a fillip to your business.

    This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects

    Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.

The connector on the upper left has 4 input, 12v, gnd, CAN+ and CAN- 3. The 4 connectors on the bottom is pretty much the same, it control 4 identical components. Each connector has 6 wires: Gnd, two output for dc motor, ws2812 data, 5v, and a switch trigger. 4. Whenever a switch is pulled to ground, it will trigger the motor to pull for 1 second. 5. Whenever a motor is pulled, the ws2812 will start to light up. 6. After 20 seconds, the motor should reverse back. And the Ws2812 strip should light off. 7. Whenever a certain CAN signal is received (will be provided), all the 4 motor should pull for a second. All 4 ws282 strip will...
