electronics projects

Hello guys You will find circuit diagram, firmware , and other necessary information the link, which is given below.   here is main link of this project : https://www.fischl.de/usbasp/ Here is the diagram for basic microcontroller circuit : THANK YOU

 HELLO guys. what we need :- Arduino uno apds-9960 Breadboard  Jumper wires here is the connection :- here is the code link :- https://github.com/vivek-chauhan7/APDS9960 here is the library :-  https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor

Hi ---------------------------------------------------------  here is the circuit diagram ---------------------------------------------------------- HERE is the code for without library -------------------------------------------------------------------------------------- /*  * ER BROS LAB  */ #define a 6 #define b 7 #define c 8 #define d 9 #define e 10 #define f 11 #define g 12 #define dp 13 void setup() {   pinMode(a, OUTPUT);   pinMode(b, OUTPUT);   pinMode(c, OUTPUT);   pinMode(d, OUTPUT);   pinMode(e, OUTPUT);   pinMode(f, OUTPUT);   pinMode(g, OUTPUT);   pinMode(dp, OUTPUT); } void n0() {   digitalWrite(a,LOW);   digitalWrite(b,LOW);   digitalWrite(c,LOW);   digitalWrite(d,LOW);   digitalWrite(e,LOW);   digitalWrite(f,LOW);   digitalWrite(g,HIGH);   digitalWrite(dp,HIGH); } void n1() {   digitalWrite(a,HIGH);   digitalWrite(b,LOW);   digitalWrite(c,LOW);   digitalWrite(d,HIGH);   digitalWri

Hi here is the simple and very useful project. parts list ATMEGA8 (you can use atmrga328p, or any other arduino) - 1 22pf capacitor -2 16MHz crystal - 1 10K resistor - 1 100E resistors -8 push button - 1 rotary encoder with push button - 1 4 digit seven segment display - 1 relay- 1 bc547 transistor - 2 buzzer - 1 zero pcb - 1 10uf capacitor - 1 100nf capacitor - 1 some wires and male or female header pins here is the  schematic diagram here is the code link https://github.com/vivek-chauhan7/Timer-Switch YOUTUBE LINK https://www.youtube.com/channel/UCY6KA8oFk1s36fyPiFEmedQ

Hello guys here you can see how interface PIR sensor with and without arduino board. use of this sensor is very easy , by connecting some wires as shown in diagram you can use this sensor. here is circuit diagram :- After connection as per diagram you need to upload this simple code :- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- #define pir 10 #define op 13 int val; void setup() {   pinMode(pir, INPUT);   pinMode(op, OUTPUT); } void loop() {   val = digitalRead(pir);   if(val == HIGH) {     digitalWrite(op, HIGH);   }   else {     digitalWrite(op, LOW);   } } -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Hi This is the simplest home automation using HC-05 Bluetooth module. parts you need...              components                                                                                  buy link Arduino Uno (any arduino works)                                 https://amzn.to/2MUYONt Bluetooth module                                                           https://amzn.to/2AyfN5t Relay module                                                                  Zero PCB 1K resistors 2K resistor 817 optocouplers  circuit diagram  here is how to connect any load or appliances with relay here is the link for code https://github.com/vivek-chauhan7/BT-automation here is the link for Android app. https://play.google.com/store/apps/details?id=com.appsvalley.bluetooth.arduinocontroller thank you for watching
