Attached schematic shows one circuit of 4 identical circuits connected end on end. Not shown is a single opamp buffer with 220R resistor and 2.2uF film cap on the output. The power bus is +/- 15v with ground. There are no pots on the board; wires will be soldered into three adjacent holes for the Boost/Cut pot--same goes for all external connections. The Q, and the a and b Freq pots, with be replaced with 2 RN 55 resistors connected in series to the wiper terminal from terminals 1 and 3. Not shown are 4 - 10uF electrolytic caps on the power bus near each circuit with 2.54mm centers. All of the resistors are Vishay RN 55, except the two 5.1k at the bottom which are RN 60. The 10uF caps are small bi-polar with 2.54mm centers. The rest of the caps are film with 5.08mm centers. The ...

I have a simple NeoPixel Sketch for the Arduino Nano. This is loosely based on the NeoPixel Adafruit buttoncycler example sketch and the tweaking4all examples This sketch cycles through 4 different NeoPixel effects at the press of a button. The button uses the ezbutton library for debounce. The limitations of the current sketch is that I have to wait for each NeoPixel pattern in the cycle to complete before I can press the button and cycle forward to the next pattern. Each pattern has a delay(), which I understand to be not best practice. Sketch to be modified is attached to the Project. Project requirements: Refactor the sketch so that: - Each pattern loops indefinitely (currently each pattern only plays once)

We designed a simple circuit to illuminate some LEDs. However, once we wire more than 7, the circuit no longer works. The goal is to get to 10 LEDs with this configuration. We would like help in selecting the correct resistor values and LEDs for this application. It would be nice if someone could simulate this using some software to ensure that it works as well. I will attach the schematic below.

I need a digital true rms to digital converter. Source is a current transformer 0-1vac for rated turns ratio.

The project presents the use of correct soil moisture sensors which helps to ease out the pain to monitor and keep records about the changes in soil moisture. Using the Arduino Mega microcontroller with Light-Depended Resistor sensor, moisture sensor, and temperature sensor, the temperature is measured and analyzed. The soil for a certain duration provides information related to the moisture status of the soil. The Arduino Mega will collect and process the data received from the Sensors. When a threshold moisture level of the soil is reached, the water will supply accordingly. This is essential because water must be provided to the plant at a particular time for a good yield. This project is highly used for farmers, Nursery professionals by eradicating traditional or manual methods ...

Unit “A” features a printed circuit board (PCB) which’s ground potential is grounded to chassis potential via a 2kOhm resistor. Unit “B” contains a PCB which’s ground potential is connected to chassis potential directly, resulting in a 0Ohm resistance. Unit A supplies unit B un-isolated with 100V, 20W of power. The wire used is one shielded pair of 20AWG copper cable of 15m length. The shield is connected to the chassis of both units. Assume room temperature. Calculate the current flowing over the cable shield by assuming the shield behaving like a third conductor in terms of resistance, explain the methods you used and describe what downsides there are in the demonstrated setup. Additionally suggest 3 measures to improve the setup
