    Hi Everybody The project i have is a controlling 5 leds from a ESP8266 using the pwm. I had a prototype pcb milled out by a friend with a LDR circuit to the A/DC IN pin, a motion sensor input, & 5 x Mosfets to pwm the leds WRGBW. I can program the esp and had a play with MCU/Lua. but due to work and family i don't have enough hours to get it

    The challenge is to explain how you would design a circuit that measures light intensity and the speed of a rotating object, the output will be displayed on a computer. The expected documents are : -A simplified diagram that will represent the general idea of the wiring (just specify core components, and only use V+, GND and a theoretical wire that

    This project is to be completed in Kicad software; the schematic and pcb layout. It is a 300amp motor controller for 3 phase AC induction motor. The battery voltage will vary between 3volts and 25 volts. It must be able to operate all the way down to 3 volts! Some boost circuitry will need to be designed for gate drive. There will be 6 mosfets total in the power stage. We are specifying to us...

    The objective is to create a 1m delay circuit in EAGLE to delayed power that feeds an array of P MOSFET transistors. The delay is to allow enough time for the microcontroller to boot up without causing any P MOSFET to activate during bootup. Updating the firmware on the microcontroller is NOT an option. The current delay can be accomplished

    Requirement for the project - 1. A slow rotating platform with a rotation speed between 15-20 sec for 10 degree and max weight to rotate will be 700 g. 2. A timer is required as the rotation should work for 3-4 mins and then stop. 3. A relay which is active for that 3-4 mins and then stops. 4. The whole setup will be in a box so if the box lid is opened then the rotation should stop and re...

    ...design has some end-of-live components and I want an alarm (piezo buzzer) added to the layout as an option. The current PCB has been reversed engineered in China, so the circuit diagram, PCB layout and BOM will be provided (in a ancient Eagle version). The PIC or microprocessor used, is the ST6210/HWD. It's no longer in production, but I've got

    We have a noise problem on an input monitor...counting noise in the background. We need an electronics engineer to look at the datasheet of the sensor we are using and how we have it interfaced to the Arduino input. This circuit operates in an industrial environment and need to be robust. the Engineer needs to look at the setup and recommend a fix.
