Hello,
I was hoping to get some help/advice on a personal project I'm working on that requires quite a bit more electronic hardware involvement than I'm used to. I can manage code, computers, microcontrollers etc fine but I'm not very well educated in general electronic hardware at all besides...
I'm trying to understand how to drive the MOSFET's in the two-switch forward, I designed a 200W DC-DC converter, 50V input 100V output but I was looking for using an MCU and IC in this case I have an IR2110 high side low side for the gate drive, I don't know if it is possible to use it? and if...
I've been looking at UCC28C43 models provided by TI. Why do we need two different Spice models such as "Transient steady-state" & "transient start-up" for MOSFET driver IC? How do we use them? When do we need these analyses?
Do all microcontrollers in power electronics have such separate models...
Hello all,
Caution, I am a newbie to MCUs. I am looking for a low cost MCU board with Bluetooth for communication with mobile app. I have purchased NodeMCU which comes with onboard WiFi. However, I would like to talk to MCU via Bluetooth directly. If I use NodeMCU or ArduinoNano, I would have...
I am using an Arduino mega to switch several of these very common relays with a 24v inductive load on pretty much all of them and I am having a peculiar and extremely frustrating issue where during switching (frequently but not always) the Arduino will reset, when monitoring the arduino's 5v...
Hi, everyone! I have a problem with a picking a microcontroller that are going to manage DEC Module 50/5. I want to use DEC Module 50/5 to manage motor made from Maxon. One problem is that DEC Module 50/5 isn't programmable. I also want to remotely control the engine using computer commands.
Do...
Hello,
I am newbie in programming the microcontroller. I would like to test the micro by blinking the LED in a pin. The micro is SAMR35J18B and I am using ATMEL ICE programmer and ATMEL studio software for the programming. I am able to detect the micro in the software but I could not find proper...
Consider a typical autonomous embedded Steering Control Module. This controller is mounted in a Commercial Truck. It assists in keeping the vehicle in it's lane.
During transition to sleep mode, real camera calibration data is written from RAM to NVM. This data written to NVM is corrupted...
Hi guys. What is the difference between these two procedures for the reset and interrupt vector. One in mplab and one in the Proteus?
org 0x00 ;reset vector
goto Start
org 0x04 ;interruption vector
goto Start
PGM code 0x0
Goto Start
ORG 4
;some code here
PGM code

Hi,
I am doing a small smart home project (model). I'm going to use an LCD, 2 led strips, 4 sensors, 2 micro servos and 4 leds. I counted that I would need about 29 pins and now I wonder what microcontroller is best to use, from the beginning I thought about Esp32 but one Esp32 is not enough and...
Hello, I am trying to implement a weight sensor. Tension simulates weight, and I've already made a sensor which is working. But when I try to enable conversion on the other sensors, ie the other AN ports, it doesn't recognize when I call adcon1,adcon2, etc. I appreciate if you can help me...
Hello guys,
I am not sure if this is the correct thread to post this topic on, but it is related to microcontroller, so here is goes.
I have a 120vac input signal coming from an existing sensor that i need to sense to my controller and then act accordingly. I have tried 2 circuitries and have...
Im trying to finish a dice game code on a PIC 18F452 microcontroller using assembly language by tomorrow morning and only have 7 errors left in his code. If i can fix the remaining 7 errors, i won’t have to drop the class so if anyone can help out tonight that would be greatly appreciated. Here...
hi
I am developing simple circuit where I am trying to detect pressure when arms coming together when hand bended. the device will be placed near the L bow of hand and when user bend the arm, the device measure the pressure and beep if pressure is higher than set limit.
I know micro controller...
Hi all,
A begineer here. I am making a simple DC motor based car. I am using the following components,
Two 12v DC motor (1000RPM, No-Load Current: 70mA (max) )
L239D Motor Driver
Arduino D1 board
Eight 3.7v 3800mah Li Battery (4 batteries for each motor )
My doubt is,

Hi, I want to measure the voltage of the fan regulator and feed into ADC pin of ESP 8266, The range of ADC is 0 to 1V, theoretically I can use the below circuit. VG1 being the load voltage taken from the fan regulator, VF1 will be driven into my ADC pin , My doubt is, can i go with this circuit...
Hello guys,
I am currently working with a mircocontroller for the first time. My goal is to achieve a PWM-signal (1kHz). While trying to generate the signal I encountered the problem that my signal seems to be moving horizontal due to inconsistancy in time up to 100 µs. The goal was to...
Update: The issue is resolved now. Please check my update here: https://forum.allaboutcircuits.com/threads/8051-not-working-after-flashing-the-program.177718/post-1613102 for details on the issue. The circuit is now successfully implemented, even on hardware.

I've been learning to program 32-bit ARM cortex-M controllers with an STM32 Nucleo (L476rg Nucleo). I've been playing with interfacing and controlling stepper motors so far. My next step is to move on to machine/computer vision and incorporate image sensing however upon some searching (hopefully...
