    wiring an arducam with the power line on a transistor

    I've set up an arducam mini 2MP plus with a nrf52DK (similar to an arduino for this set up) to take pictures. Ive got the board and camera working when the camera is wired with the VCC line and GND wired directly into the boards 3.3v line and ground pins. The arducam uses about 100 mAmps when...

    K thermocouple values not stable (Max31855) / Information on Relay

    Hello I have a max31855 Datasheet , using arduino (1.8.13) and I am seeing the values of the thermocouple bouncing, I would love to say that the problem lies in the code but the code uses a library that is a bit hard for me to understand . Or that the problem is in connection I also noticed...

    Hardware Board parameter missing in Matlab simulink

    Hello i am using Matlab simulink and the hardware board parameter section is missing, so i think that is why i am getting the error of "Could not execute target data map file 'template_grt_rtw\template_targ_data_map' or it does not exist. Stop the target, delete the template executable...

    110AC motor driver using arduino.

    Hello everyone, I am working on a project and don't know where to start. I worked with DC motors before but I haven't worked with AC motors, and I don't have much experience with 110VAC as well. What I have is a motor with 2 sensors. The sensors are used as end of travel switches. I already...

    Sparkfun Servo Trigger - Programming ATtiny84a from Arduino as ISP with Atmel Studios 7

    I cannot seem to program the ATtiny84a with Atmel Studios 7 with an Arduino Uno as the programmer. I got Atmel Studios 7. I opened the Sparkfun Servo Trigger solution. It asked me to upgrade or something so I said yes. I do not have a programmer but I do have an Arduino Uno with an ATMEGA328P...

    How do I send data to a Nintendo 64 (n64) console, from my computer?

    I have had this idea for a while now. "What if I could play with my friend on my n64 over the internet?". I realize I could just use an emulator, but I wanna do this with hardware. I can set up a program that can send controller data and I'll stream my TV, so basically all I need at this point...

    tennis racket/ball speed/impact detection using the MPU-6050

    I have a mini project I'm trying to accomplish using an arduino nano and an mpu-6050. What my code does is basically trying to find the speed of the racket on impact and perhaps the impact force on the ball. What I have at the moment is that it it detects the interval of the tennis stroke and...

    How do I manage voltage regulation for variable input

    Hey all! I'm trying to build an LED frequency counter. My input signal is an LED I'm using as a detector recieving from an output LED on my signal generator. I'm using square wave output to emulate pwm and my circuitry is going to process the signal to output a 5v logic output that can be read...

    Arduino PID soldering station with zero crossing detector

    I build on bread board the attached schematic and I uploaded the attached code to an Arduino Uno. I tested each part of the schematic (the pot, the OpAmp, the zero crossing detector, the optotriac) and they are working. The problem is that when I start the circuit I got the attached screenshot...

    Powering 10 servos from a single Li-Po

    I could use some perspective on a circuit I'm planning to build. It's a robot with 6 standard servomechanisms and 4 microservos. I'm set on using a single power source and three step-down converters to feed most of the servos + Arduino Uno + PWM driver with 5V but also supply 6V to two servos to...

    Darlington transistor POWER AMPLIFYING

    Hi all, I just couldn't find the answer on web so I had to ask you guys. Based on my understanding, input power is ideally equal to the output power of a circuit unless it is dissipated to heat. So I was looking at the ULN2003 Darlington controlling a 28byj-48 stepper motor using an Arduino...

    HC-05 Module AT command mode won't respond

    I've been trying to connect two HC-05 bluetooth modules together as master and slave devices. I know that to do this i need to establish one as a slave device and one as a master using the AT command mode. I am using an arduino nano with each of the modules and the circuit i have used is shown...

    How can a AC source be regulated to specific DC?

    Currently I am trying to power an Arduino project with a mechanical battery. I am using a stepper motor (NEMA23) as generator for it only needs low RPM to reach full potential (Around 600 RPM). Output of the stepper was determined at 1.8A AC @ 33V. This should be enough power for all the...

    MOSFETS not switching

    Hello all, Im having trouble switching my mosfet with an arduino within my asymmetrical h bridge. I had it working with an 8 channel relay and switched to a faster isolated switching device, (Dual high power mosfet trigger switch drive module (5v - 36V) 15A). I believe it's because my winding...

    connect the STONE module to the arduino

    I have the STVA070WT-01 model module from STONE technology I'm testing with an Arduino Leonardo or Uno. I also have a max3232 rs232 serial to TTL adapter to connect the display to the Arduino. Also, haven't looked up what pins to connect this to yet if anyone knows. I won't know how to send a...

    Arduino Motor Circuit Only Getting Less Than 1V

    Hello, I have built this motor circuit for my Arduino and when running it only gets less 1v and the motor spins very slowly and my bigger motor doesn't spin at all. I have attached the diagram that I followed below. The Motor should be getting 5v from the Arduino although something seems to be...
