...eight 28BYJ-48 5V stepper motors (sixteen total), with a ULN2003 driver board for each motor. - Each group will be controlled using four cascading 74HC595 shift registers (eight total 74HC595s), and all motors will run for a set amount of time (~5 seconds) then stop, until the button is pressed again. - Group one motors (eight total) will run clockwise for ~5 seconds then stop. Group two motors (eight total) will run counterclockwise for ~5 seconds then stop. - A debouncing routine will lock out the button for a 5 second delay to prevent the button from accidentally retriggering. 2. **Project Specifics:** - Arduino Uno with eight 74HC595 shift registers. - Motors to be controlled: 28BYJ-48 5V Stepper motors. - Number of motors: 16 motors, 16 ULN2003 dri...

...Necesito un skech Arduino para el control de luces mediante el microcontrolador ESP8266, en concreto, el módulo ESP01. El programa deberá ser capaz de conectar 3 de estos módulos, uno actuará como servidor y los otros dos como clientes, los dos clientes serán iguales y con una serie de leds conectados. Para aumentar el número de salidas del ESP01 en los clientes, se utilizarán shift register, 74HC595. Los tres equipos estarán alimentados independientemente mediante baterías lipo de 3.7V y capaces de soportar carga micro-usb. (¿Qué equipos necesito para esto?)

I need s...should control 15 identical switches. Communication between the MCU and the host PC should happen via USB. USB should also be be used for the power supply. The whole design should be optimized for minimum power consumption. Min. 2 extra output pins of the MCU should kept unused to allow for future extensions. Open questions: - What's a suitable MCU? Maybe a Digispark (ATtiny85) with two cascaded 74HC595 shift registers to achieve the required number of output pins? Or maybe another ATtiny with more native output pins like the ATtiny4313? Are there any suitable minimalistic, Digispark-like ATtiny development boards with more output pins and USB support? - What's a suitable transistor? I'd like to buy and assemble the parts by myself.

led cube 16*16*16 построенный на базе 74hc595

I need an AVR code for atmega328p to be able to read PITCH angle, use LED to display sign (-). Display results on Two 7-Segment displays (-90 to 90) with help of Two shift registers (74hc595). Code needs to make use of LOW Power Mode, The <avr/sleep.h> and <avr/power.h> libraries have useful functions you can call to do this, or you can implement register writes directly by yourself. Add a tare button that, when pressed and held for one to three seconds, re-zeros the display to whatever current angle the board is being held at. If the button is held down for at least three seconds, this tare value should be reset to zero. Write this value to EEPROM so that when the board is powered on, it loads the value from EEPROM to recall this setting. You should provide an LED that ...

Instead of having the shift register count up continuously, I need to build a "bar graph" to visualize the value of an ADC pin. Start by adding a potentiometer to your breadboard, wiring it into one of the ADC pins. Using the format of the ledArray module as a guide, create adc.h" and " files, and provide appropriate function(s) for getting an ADC reading. Hint: you'll need a function that performs an ADC conversion and returns the result. Call into this ADC module from your sketch to get a current ADC reading, and visualize this by writing appropriate values to the ledArray module. Do this continuously at a reasonable sample period (say, 50ms). Note that bar graph should be lled | i.e., all LEDs up to the appropriate mark should be illuminated.

i need a timer with 3 units of 7 segment with 3 shift register (74HC595), the timer shuld start with a trigger (like button) and tone, and when the count down is finish there need to be a tone and action (like open relay). i have a basketball game that the display is work the same and there is a counter of 59 sec, you can copy most of the work from there, you just need to add the min digit.

Looking for a circuit created using Eagle CAD for schematic with PCB. Based off Arduino prototype using ATMega382 with 74HC595 shift register. Power: 12v 7.2ah sealed-lead battery, Inputs: 4 buttons, Output: 16x2 LCD (connected to register), 2-12v 2.4 brushed motors using H-bridge (MOSFET).

...was disconnected, i.e. the latching aspect of the relays means they will still be connected until the reset (Normally Closed) function is triggered. I would also like to be able to include an audio Bluetooth connection as one of the switched inputs but I’m not sure how to accomplish this, perhaps a separate board. I am thinking of accomplishing the switching through shift register chips (e.g. 74HC595) triggering DTDP bipolar relays. The relays will most likely all be 5 volt dual coil and be powered separately. As best as I can work out a 4 input - 4 output setup using DTDP relays will need 16 relays with each relay requiring 2 switch pins (one to latch and one to release the relay) making a minimum of 32 shift register pins (so 4 shift register chips) . For reference, ...

To operate a 6 single digit score board by one momentary push button for each 7 segment digit. One push on any of 6 button input/interrupt need to count up that corresponding digit by 1(one) rewrite the multiplexed digits's driver (74HC595). You may need to include: debouncing and/or interrupt routine and re writing the above 6 of 8 bit shift registers. Arrays to store updated output values. Reset when power turned on to 000000 display values. Displayed values are decimal 0-9 than again 0-9... This code should run standalone on a ATmega2560. Output Ser.
