A DC load is an essential testing tool for any electronic enthusiast, especially for testing and repairing power supplies. An adjustable DC load can limit the current at any desired level, which makes it suitable to perform various tests because some problems of the feedback loop are only...
JSON and XML are the most common data serialization formats. The Internet is a hub of billions of different devices, applications, and services. These devices and applications are built in different programming languages and around diverse platforms. For all these entirely different devices and...
Hello there,
I'm a newbie in Arduino, and I tried to make two battery-level indicators to be displayed on an OLED display. Once I uploaded the following Arduino code, it showed two battery level indicators with percentage values. One battery level indicator should only work with the voltage...
I have bought Xbee s2c modules for my project and I wish to transfer sensor data from one xbee to another in non-broadcast mode using arduino mega at transmitter side and arduino uno at receiver side. Please help me with the code for arduino mega and uno and the configuration parameters to be...
Hey guys,
Ive been working on a BMS using an LTc 6804-2 cotrolled with an arduino uno.
I am simulating the circuit throught proteus 8.10 and i have been having some issues.
While the proteus schematic seems not to have any problem, i have uploaded an arduino code to the arduino in proteus and...
Hello Community !!
My project is about doing a simulation of a circuit in order to display a signal related to my pulse sensor. Actually, I'm not quite familiar with coding using the C++ language, I tried to make a flowchart that describes what is the code doing in general. So what Do you...
Hello Community! I'm facing some problems to understand the code that I want to work with on my project. I found it hard to understand some comments on the code, that I found on Github. In brief, I'm looking forward to doing a simulation of a signal related to my heartbeat sensor. You'll find...
Hello community!
I'm new on this forum. I'm working on my heartbeat sensor (pulse sensor) that uses PPG technology, i've got some troubles to calibrate the sensor. Actually, i don't know how to choose a "threshold value" in order to have the shape of that ppg signal when i put my finger on it...
Hello, I am working on a vehicle speed detection system using the hb100 doppler radar sensor. I am simulating on proteus first before I start the construction process, i couldn't find the library of the hb100 sensor to add unto proteus, so i made use of an astable circuit to act as the HB100...
I have a flight instrument with several + 0 - meters with no inputs they are read 0. But they can be made to move by using the diode test on my Fluke.
I know I can use PWM to drive in only one direction at a time. so some times the wires need to be connected:
for + 1 pwm 2 ground
for - 2 pwm 1...
I am attempting to make a circuit with the KT3170 chip. Outputs from chip sent to Arduino pin. Arduino will receive 4 numbers and display them on the LCD screen. It's working
But sometimes the Arduino will take the value from a number 2 times.
Like I dial 1 . Arduino will receive a 11 .
I...
Hi, I have uploaded on my Arduino Uno the attached code, and I am facing the following issue: If the temperature is set to max (about 18mV on the Thermocouple) then if I rotate the pot to minimum temperature, the voltage on the TC starts to reduce, until it reach about 17mV. Then it goes very...
Hey everyone!
I am making an ESC of my own we have been using Mosfets,created our power supply and driver circuits using opto couplers, and using H-brigde for switching the mosfets in perfect order to run the motor
everything is going fine except the programming part. I have been doing it for...
