I'm traying to build an existing project (Arduino Data Glasses for My Multimeter).I'm using Arduino Uno - Hm-11 Bluetooth module - OWON B35t+ multimeter - Micro OLED. I used the same code but it didn't work for me. The actual reading for the multimeter not shown on OLED. The OLED shows CONN when I open the Multimeter and LOST when I close it.

I'm looking to build a 20x20mm development board similar to the link below. Ideally, it would work with Arduino IDE and have the following features. 14 - Digital I/O Pins 2 - DAC Pins 4 - I2C Pins (2 pair) 8 - Analog I/O USB pins on the PCB

Only experts! Let's discuss over private chat.

My project is very similar to having a wristband on, that +1 counts each time a user walks through a door, so the frame has a 'hub' with tracking technology on, so does the wristband, both will need battery features and to be charged. Please ask for more questions but I am flexible with the technology, the information should also feedback through to an app. Each user will have a wristband, so there are multiple wristbands, and there are a few 'hubs' too. So it's 2 parts, a wristband and a 'hub', that connects to apps etc.

I want to have possibility to change CID number on any SD Card. It can be Arduino or combination of hardware (PCB) and software - it doesn't matter. The project will be closed when I will see that device or hardware can changes a CID number of a card that I will send to the developer. P.S: You do not need to suggest a solution for Samsung EVO+ SD cards because I already have it. I need solution for any SD card brand. Please that you do not waste my time for trying ! Sign up only if you have guaranteed Solution.

I need a simple sketch that will run on an Arduino with ATMega328PB processor. The sketch is very simple in that it must do the following: Sleep pwrDownMode(); for XXX seconds Wake Up after XXX seconds Increase a counter (countWakeUp) If Interrupt 0 is pulled low for XXXX milliseconds write to Serial "Short Press" If Interrupt 0 is pulled low for >XXXX milliseconds write to Serial "Long Press" Go back to Sleep pwrDownMode(); for XXX seconds

We need someone to build a simple Arduino solution. The unit has to detect a Bluetooth signal from a Bluetooth Beacon if the field transmitted is a 1 then the Arduino turns on a green LED. If the field transmitted is a 0 then the Arduino turns on a red LED. If the field transmitted is a NULL then the Arduino turns no lights at all. The solution must include all hardware and software including housing for the unit.

GSM and low power experience is a must for this job; We would like to improve our existing PCB -Convert to full SMD design (2 layer is enough even can be 1 layer) -Convert to low power design -Convert to cost effective design -Arduino to Atmega328P or 328PB conversion -Add PCB GSM antenna (currently using external) -All external I/O should be on PCB PCB dimensions can be changed but limited to our box. (there is enough space)

We require suitable logic and corresponding Arduino sketch for controlling a pump and valve based on the required pressure. We will be using an ESP32 board for this project and we require precise pressure control. As this system has to be used with different types of pumps and environment, we need the system to learn itself each time before we start pressurisation or depressurisation. Also, the pressure can be checked only after switching on and off the Pump or valve (Simultaneous checking not possible) and we have to avoid frequent switching on and off hence we need a system to adapt itself and reach the objective. We require suitable logic and Arduino code only we will take care of all associated electronics.

I need to control the functioning of a tangential fan at a very low cost: this can be done by connecting a mass air flow sensor with a controller (probably Arduino/DM1 or similar), so as to close a circuit and getting a led on and a small alarm buzzing when the quantity of air expelled by the fan lowers more than 5% of the normal flow. I would like to use this mass air flow sensor https://www.amazon.it/Flussometro-aria-debimetro-stufe-pellet/dp/B08GQ9P93Z/ref=pd_sbs_79_4/260-9400044-9712829?_encoding=UTF8&pd_rd_i=B08GQ9P93Z&pd_rd_r=039e4495-4794-47d7-8af2-df329b7ed5a7&pd_rd_w=JWNaH&pd_rd_wg=D4eep&pf_rd_p=26de63c3-766e-46eb-a5d4-5196554180e1&pf_rd_r=M9AHA4M4PZGYC5S36138&psc=1&refRID=M9AHA4M4PZGYC5S36138 The fan sample is like the attachment shows

have a 63" wide drum sander with a table that needs precise speeds. want to run table in one direction for about 120" pause and reverse. need to be able to change speed of travel, pause time. need to be able to fine tune travel amount. person who started arduino controls disappeared. table is assembled, with a nema 34 motor 200 steps, DM860T stepper driver, 36 volts dc converter. tried programming myself from library and get problems with overflow. ran OK but not enough travel. changed from uno to mega board, still had overflow issues. need to spend my time on marketing, rather than learning how to code. will have other projects to automate material handling in coming months as we are dealing with large and heavy pieces that need to be loaded into jigs.

I need a test program that can send data over i2c and receive responses. The program should run on Arduino OS (specifically Argon board). I must meet the industry specification for communication: 3.3V i2c with standard mode transmission , 100kHz. See the attachment. This is a subset of the full document. there is a similar structure for reading and writing data which is also described in the document. The user (me) should be able to send a command to the first board via Serial input over USB. For example "0x200610" which should request a response. The first board will send this request on to a second board which is already programmed to send a response. The program needs to print the response (in this example it isn't clear what the response will be but p...

Hi -- I am a DIY maker -- with access to a wood CNC router -- I really want to make a replica version of this kinetic art I have fallen in love with -- on a fairly large scale, 4'x8'+. There is a couple versions -- but its usually controlled by 8-16 servos. I found a way to make the mechanism to move the hands in 2 directions on 1 spindle (like a clock) The problem is I don't know what kind of servos to get... how to control them... and how to find or make software that allows me to visually program the patterns. I would really like your help me to order the right parts, controller, and software to make it happen.

So currently I am trying to build a custom microbalance based on the Arduino MEGA 2560 chip, some At-cut quartz crystals with a 6MHz resonance frequency and a crystal oscillator driver (SN74LVC1GX04). Firstly, I want to try and make a prototype that prints the frequency value through the serial port. If this works properly I will try to add a display, an SD card and maybe some Wi-Fi if it's not too complicated. However, before trying to connect the crystal I wanted to see how accurate and stable can the frequency measurement of the ATMega 2560 can be since for this application they should be as good as possible. Main problem that I am encountering is that arduino Mega 2560 is running on a 16MHz ceramic resonator and frequency mesurements are not accurate or stable. M...
