Microcontroller Jobs
I have a bunch of board I need to make and have tested. I thought Mumbai would be a good option.
The device must be able to detect and discriminate pulses from an analog wave form, perform a counting function and transmitt the count via serial RS485 com protocol.
I would like to build a physical device that allows me to perform a simple ON/OFF action. I already have a Kinco HMI/PLC from here: [login untuk melihat URL] that is already programmed to do this operations: 1. Turn on a cooling fan - turn it off after 1 hour. The fan could be something like this: https://www.amazon.com/SUNON-EE92252B1-0000-A99-Ball-Bearing-51-5/dp/B00B8869PI/ref=sxts_sxwds-bia-w...

I would like to build a physical device that allows me to perform some actions in Zoom with an Arduino Device via a emulated Human Interface Device. When pressing the button, the LED should go on and go off again when the button is pressed again. If the button isn’t pressed in three minutes, turn off the LED. Some web examples include: Zoom Meetings Physical Mute Button : 7 Steps (with Pi...

System: Arduino Mega 2560 / ATmega2560 with GSM SIM900 attached Needed: FOTA Suggestion, what I would need: - Bootloader capable for FOTA (maybe most important part) - Firmware to integrate into my main project for handling the firmware download from the website via the SIM900 (the hex-file output by Arduino IDE) (medium important) - Rewrite the firmware with the downloaded new version (important...
Bipolar Light Emitting Diode (LED) is a special LED that has red and green output. It can be used in many applications such as streetlights with auto-intensity control, mobile phone camera flash, signage, automotive interior, home decoration and others. For instance, to have a green and red bicolor LED, specific driver circuit is needed to drive the terminals (green/red). This project involves des...

The main part of the circuit is finger print module. This sends commands to the controller when ever finger print is matched. The Microcontroller receives these commands from the finger print module and uses the internal memory to store the attendance. Keypad is used to send the requests to the controller either enroll the new one or to save the attendance or to exit. LCD display displays the mess...

This will be an ongoing project.
I build musical instruments. We build one instrument with a very high frequency that is annoying to practice, though it is used extensively in orchestral performance. We want to make it more accessible to the general playing population. My idea is to make headphones that drop the pitch of the instrument by FFT an octave lower. I wonder if it is possible to modify a pair of noise cancelling headpho...

You do *not* need an Arduino. You do *not* need an ESP32. You will normally work 1 hour/day for 10 US dollars/hour. But, I presume Freelancer will pay you 9 US dollars/hour after they deduct their 10% fee. You will normally work 20 days each month for 9 US dollars/hour. If you are very intelligent and if you solve engineering problems scientifically then I will pay you to learn C/C++ on Arduino...
Current system is successfully using SDIO based WIFI module with embedded Linux kernel 4.4.x. Recently we changed the wifi module from TI to RealTek.
