Hi, I am new to electronics, trying to build a whac-a-mole machine based on this tutorial Circuit of the tutorial I am currently just working on one of the solenoid actuator, hoping to make it responding to the state of the limit switch. Circuit of my attempt of making one solenoid work...

I need to recognize a signal from an IR remote, not to use a library for working with IR remotes/receivers. How can when the button is clicked to display its name. I have PIC12F615 microcontroller with this code: code and 5 buttons connected to him and I need recognise which button pressed. Why...

Dear readers, I followed this code at here and built its circuit. However, the stepper motor does not get enough power or even torque or speed so that when I can stop the wheels easily by slightly touching them? Are there any solutions for this? I have checked that my battery are all...

Hello! I am a beginner at Arduino. I need to implement a simple circuit to control various LED glow scenarios and their reset using tact switches. I request to please help me with this project. I am attaching the image of the assembly done on bread board. The circuit is intended to function...

Hi everyone, There are boards with IR sensors on the market that looks like this: the IR.PNG picture I have all the components to build one myself with the Arduino Uno, VCNT2020 sensor and LM393. The schematic is the example.jpg picture (it's the schematic of the sensors on the market) The...

I’m dabbling in Arduino and having trouble running two sketches on my Arduino UNO simultaneously. The first is about a program that reads temperature and relative humidity and the second is a program that reads barometric pressure. Both programs work independently, but when I try to combine the...

This is the problem I am trying to solve: I have two Arduinos , side by side running the same sketch for led panels which are also side by side. It is an art work hanging on a wall. Each Arduino is running two 16X16 panels . The Arduinos need to work in sync to keep the pattern changes...

I have a marble sorting project in which I want to use a load cell to move my servo motor a certain degree. I have calibrated the load cell so it measures my weights accurately, but I need to incorporate code that uses this measurement to move the servo. I'm using the Arduino app with an HX711...

Hi everyone,I have been working this lasts month on a little Arduino project about making a remote control car. I'm using 2 Arduino Uno boards, one for the car and the other for the remote controller. I'm also using the module ESP8266 12-f for sending and receiving orders (I use the AT...

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...
