    Projet personnel : on a plusieurs led que l'on veut allumer à des moments différents L'esp32 reçoit les informations du moniteur série (image), il faut parser le JSON qui contient la configuration (date, heures, minutes, box= led) , l'enregistrer sur une carte SD (liaison SPI) pour ensuite executer les configurations au moment voulu. Un accompagnement en écran partagé me convient aussi

    I want a samll aurdino or esp32 based board with schematic which can generate a alarm if distance above a threshold. I will like to use multiple ultrasonic sensors ( upto 6 ) and if any one of them give reading above a limit it should generate a hooter. System will work on 12 v dc supply. Like cost to be lowest. Work to be done in 1 week with testing. I will assemble and test unit as per details and guidance provided by developer.

Output voltage range: 0-3.3V. Midpoint Bias near V=1.65V (half of 3.3V) Operational Amplifier model will be defined before start the project. We have some circuits tested but with problems as clipping and sensitivity signal. Signal amplification should be the higer possible. In oder to avoid the noise, a 10-15Hz filter can be used. We can cut any input or output signal above a specific voltage threshold Battery used: 1x3.7V (voltage used as input for sensor = 3.3V) Software to use: KiCad for schematic and any other software for simulate it (for example LTspice).

In the attached photo you can see an ESP32 break-out board working as a sender. The main issue I have is the small range of all that (only around 15 meters)

    Hola, Tengo una esp32 conectada a un modulo led rgb, también tengo un calbe conectado a uno de los pines. Hice un codigo que cada vez que toco el pin, el led prende el color que deseo que prenda: si toque el cable 1 vez se prende el verde, si toque el cable otra vez se prende el rojo, si toco el cable nuevamnete se prende el azul y si toco nuevamente el cable, el led se apaga y vuelve y repite. La idea es conectarlo con los skill de amazon para que cuando le diga a Alexa que cambie el color, lo haga, y si lo toco con el cable, cambie según como lo describí arriba. Los cambios de color deben almacenarse en una bd: debe ir la fecha y el color que cambió. Gracias

    Hi Deep K., Hi Deep K., I'm looking for someone to help me with my project I'm doing on an ESP32 using WIFI AP and ESPNOW with a WEBSERVER interface 1. Communications of all ESP32s from the ESPNOW network to each other on events such as trigger input. 2. Communications between ESPNOW network and Webserver on a MASTER ESP32 now it only works in one direction so the master sends signals they execute but I have no tracing of the execution. 3. Interfacing with Android smartphone APP you should help me receive external inputs via WIFI server and respond to the execution of the required processes. Kind regards Philip

    Hi, We already have a working recorder which saves wav files to an SD card (CPU already reduced to 80Mhz). Worked great but we need to lower the power consumption (Now: 30mA). I wish to get less than 5mA. Hardware: Digital mic (I2S or PDM) and SD card connected to a ESP32 I am pretty sure it is possible to record wav files in light sleep mode. Here is what i have in mind using I2S in the example. But not 100% sure if that works: - In light sleep mode the I2S interface writes data from the I2S microphone to a buffer (I hope that DMA or any other memory is accessible) - A timer wakes up the main CPU when the buffer is full which writes the data to the SD card - I2S and the main CPU can't have access to the same buffer at the same time. So once the timer triggered. I2S starts ...

    I made an ESP32 receiver-webserver program (ESP-now protocol in Arduino IDE) but what is missing from my code is the following: I want when we make a refresh on the receiver's webpage the data to be preserved (imagine that 10 senders for example send each of them just a string as their own id for being recognized by the receiver and a char message like "free" or "duty" which make the corresponding region-square for the particular sender green (free) or red (duty) on receiver's webpage. What now happens is: If I refresh the page all the squares start from green. I thought as a solution: the senders to send every for example 30sec the last message that they have sent but that means the senders all the time are awaken up (via timer) so as to send again the...
