Fundamentals Wk 3

I have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds. What's the procedure to connect the components? What's the Arduino code (C++) for this project?

Please explain detail, Thank you  List and explain types of Fire Extinguishers. What's the difference between Mechanical safety vs. Electrical safety Key Term: MSDS Key Term: Chemical spill

Write the types of fuses

ACTIVITY TITLE: SAFETY PRECAUTIONS ON ASSEMBLING ELECTRONIC LIGHT DIMMER DIRECTIONS: Look at the pictures below and write something about hazards, how it can harm someone and what OHS strategy to be follow. You can write your answers in English, Tagalog or combination of English and Tagalog. LOOK! THINK! WORKPLACE DO! HAZARD/ACCIDENT What is the Can the hazard OHS strategy? hazard? harm someone?

36. Electrical explosions directly into the face of a person working on or near energized electrical equipment can and will cause serious injury or death. OSHA laws and NFPA 70E have strict safety requirements for working on electrical equipment. The basic rules are to turn off the power before working on the equipment and to wear the proper type of nonflammable clothing. To further provide safety for the worker, the National Electrical Code has a requirement pertaining to arc-flash hazard warning. This requirement is found in a. 110.16 (A) b. 220.1 of the NEC C. 330.1 d. 410.5

2. An Ohm meter connected to a resistor reads 1.00523 KQ at 15°C and reads 1.00754 K at 55°C. What is the resistor reading (in KQ) at 37°C? 3. What does it mean for a sensor to have "Hysteresis"? Give an example. 4. Type J Thermocouple is used to indicate temperature. There is no separate “code junction" connect to the thermocouple; the connections are at 25°C. The thermocouple temperature measuring junction is placed at different temperatures. What is the Voltage reading at 0°C, 25°C and 75°C?

what is error in mesurement system? Also discuss its types

I have an O Gauge track and would like to convert it into a “sensored” track. Additionally, I would like to connect that track to an ESP-WROOM-32 board that should flash an LED whenever the track detects a non-moving train. Please list all the components (and how many of each) needed. Also, what’s the procedure for connecting the components?
