Yes an Arduino can be used as Oscilloscope without any additional hardware. Burn this code to Arduino const int probePin = A0; void setup() { //Setup serial connection Serial.begin(9600); } void loop() { //Read analog pin int val = analogRead(probePin); //Write analog value to serial port: Serial.write( 0xff ); //can be skipped… Continue reading Arduino as an Oscilloscope

Burning Arduino Bootloader to Atmega8 or other Atmega
This is for all who are having problems in burning the Arduino Bootloader on an Atmega8 or any other Atmega Processor using a Arduino Board like Arduino Uno. The processor for the first time burning will have to be used with an external oscillator. I was trying without the external oscillator (was depending on the… Continue reading Burning Arduino Bootloader to Atmega8 or other Atmega
Eagle PCB Library for ESP8266 ESP-12
Eagle PCB Library for ESP-12 Please note though the library file is named as esp-12e, but it is for esp-12. The ESP-12E version will be published soon. Somehow I couldn’t find a proper a library on the internet. I found only one but that had wrong pin spacing. Download the esp-12e eagle library here For… Continue reading Eagle PCB Library for ESP8266 ESP-12
Eagle PCB Library Atmega8 TQFP32
The Atmega8 TQFP32 package that is mostly available, for Eagle PCB, has the pins too thick to be handled in DIY or Homemade PCBs. The Atmega8-AI package in the attached library has been modified such that the pins are wide enough for proper placement/soldering of the chip and thin enough so that there is sufficient… Continue reading Eagle PCB Library Atmega8 TQFP32
Eagle Library for XC6210 LDO Voltage Regulator SOT-89-5 Package
XC6210 is a LDO Voltage regulator from Torex Semiconductor. It is available for various preset voltages starting from 0.80V to 5.00V at 0.05v increments. It is capable of delivering 700mA. The 3.3v version has typical drop of 70mV at 100mA. Here is the datasheet attached. The chip is a bit delicate, I damaged two chips… Continue reading Eagle Library for XC6210 LDO Voltage Regulator SOT-89-5 Package
