Also 2 analog inputs 0-5V for 2 kinds of safety edges. Find also the list of peripherals in the attachment. The pulse generated by the motorcontroller won’t exceed 500 Hz with our current motor/motorcontroller configuration. (see peripheral list: section motorcontroller) In total we need to have: Digital inputs: 12 Digital fast inputs (counter): 2 Analog inputs: 2 Digital outputs: 6 Analog outputs: 2 Key deliverable: A fully programmed NUCLEO-G491RE STM32 and ESP32-DEVKIT...

    ...alternately to represent the emergency lights. The motor will power the back wheels and the sound will play through a small speaker as a siren and horn. Here are the requirements for the project: I believe the Arduino MKR Zero would be a good fit since it has the integrated micro SD card holder and sound processing capabilities. It also has an integrated battery charger. The Arduino needs to be powered by a rechargeable Lithium Polymer battery like 3.7 Volts. - Control LEDs: I believe I can get by with two white 3mm LEDs. I will install fibre-optics to transfer the light from the LEDs to various lenses on the fire truck. The LEDs should flash alternately. - Control Motor: Apart from the LEDs, the circuit should also be able to control a small 3-4 V motor. A potentiome...

    Small ePaper Shelf Tag PCB Design Έχει λήξει left

    Hello I'd like you to create an ePaper module PCB used for an electronic shelf tag based on the ESP32 chip. This device is similar to what you would find at a modern retail store, dynamically updating the tag as prices change. Attached are schematics and references for my desired components. I'd like to use the new ESP32-C6-MINI-1-N4 unit as the main controller, as I'm very familiar with ESP programming already, and want to take advantage of its many connectivity options including BLE, Zigbee, and Thread. The ePaper display itself will be the Pervasive 2.13" display using the ZIF25 connector and SPI protocol. Schematics and additional reference details are attached, please read these carefully to ensure the ePaper display module functions accordingly. I...

The master device should feature four initialization LEDs, each corresponding to one of the four slave devices, indicating their readiness for communication. 2. A Timer button will initiate a countdown for three minutes upon first press and pause the timer upon the second press. LED indicators will signify the timer's status: red for off and green for on. 3. Four LEDs will blink in response to button signals received from each slave device, with a restriction that only signals received while the timer is active will trigger the LED response. 4. Two additional LEDs, one red and one blue, will blink upon receiving button signals from each team's respective slave devices (B1 to B3 for blue, R1 to R3 for red). ...
