    LM317 Help

    Hi, I have a SIM800L module with no voltage regulator on it. I have power it between 3.7V to 4.4V. I was using LM317 to regulate the power from the supply (4.6 to 5V) using two resistors 220Ω and 470Ω When building the circuit, the output voltage was 3.1V which lower than recommended and might...

    RFID PICC Write to blcok 0

    Hi, I've been exploring RFID and I'd like to do different stuffs. Knowing that in the PICC memory block 0 is a manufacturer's data, I would still like to know how to write in this block and change a PICC's UID Thanks!

    Solar Panel School Project

    I bought the solar panel at the local electronics store and the only detail I have for my solar panel is that the vendor said it is 3V and the size is about the size of a 5" phone. There were no any mark printed but when i checked on my multimeter, it produces 2-2.5V.

    Solar Panel School Project

    Hi, electronics newbie here, we currently have a project in school about creating a miniature city with generating electricity. I chose Solar energy. I bought a small one with max output of 2-3V. I hooked it up with a MT3608 Step Up module and wired parallel with my 5mm LED lights hoping that it...

    PID Corretion to PWM

    Oh yeah.. But how can I turn these corrections into PWM that such ESC's can understand? Thanks.

    PID Corretion to PWM

    Hi! I just got the concept and implementation of PID control loop. Right now, I'm having a problem how to turn PID corrections into PWM for ESC in a quadcopter. Thanks in advance for the awesome replies! :)

    ESC and Motor using Variable Power supply

    Let's say the supply has max of 30V, 5A and my ESC has a characteristic of 30A?

    ESC and Motor using Variable Power supply

    Hello everyone, I am planning to create my prototype of my AVR based drone. I'm first going to use two motors and ESC's on a balance platform to test the PID. I would like to ask if I can power the Motors, ESC's and the electronics with a variable power supply? Thanks! :)

    Learning PIC Microcontrollers

    I really want to proceed to PIC. I already have spent almost 2 years experience in experimenting and studying in arduino. It seems like I want to proceed to a faster performance than arduino and interfacing/programming it with original C language or if possible assembly.

    Learning PIC Microcontrollers

    Hi, I want to learn PIC Microcontrollers. About how to program with pickIt2 or pickit3, basic configure settings, PWM, MPLAB, I2C and SPI in PIC, and interfacing sensors. The book I found interest is this "PIC Micorontroller and Embedded Systems Using Assembly and C for PIC18 By: Muhammad Ali...

    Arduino PID Controller Help

    Hi, I've seen interest in creating my own quadcopter flight controller using Atmega328p(arduino) and some sensors. One feature a flight controller must have is a PID control (Proportional Integral Derivative) which makes a quadcopter stable. I've searched how to create one, however I only...
