Int statusSensor = digitalRead (soundSensor) //define variable of the Sound Sensor status PinMode (LED, OUTPUT) //define LED Strip as output PinMode (soundSensor, INPUT) //define Sound Sensor as input Int soundSensor = 8 //define Sound Sensor Pin The Drain output of the transistor then triggers the LED strip corresponding to the input sound signal. It also has a low Rds value which will help in increasing the efficiency of switching circuits.

I need to read the old eprom and then modify the old ecu to fit a more modern 28C. Though my main goal is to modify an old Renix ECU that uses a Bi polar prom 82S147AN. I have built the circuit purely to educate myself.I RFZ44NВ is known for its high drain current and low switching time. Arduino based parallel EEPROM programmer Live The collector output of the transistor goes to the Gate of the IRFZ44N transistor. When D9 is set to high, the outDC signal acts as a control signal to the base of the BC547 transistor. Now, using the digitalRead() command, each time the sound sensor detects a sound (status sensor = 1) it sets the pin D9 of the controller to high using DigitalWrite(). I will be attempting to use an Arduino to program a parallel EEPROM / NOR Flash which can then be used to replace the ROM in older games such as those for the Gameboy, NES or the SNES. Now to the working of the controller, D8 is defined as the sound sensor input while D9 is defined as the LED strip out using the pinMode() command. The module feeds the analog out at pin A0 of the controller & the digital out to pin D8 of the micro-controller. An AC audio Signal is taken as input by the KY вЂ“ 038 sound sensor module. Arduino parallel EEPROM programmer (Ben Eater design) for at28c256. The working of this circuit is pretty simple. Arduino parallel EEPROM programmer (Ben Eater design) for at28c256.
