the circut for the talking robot code for the talking robot int motorPlus = 5; int motorMinus = 4; void setup() { pinMode(motorPlus,OUTPUT); pinMode(motorMinus,OUTPUT); } void loop() { digitalWrite(motorPlus,HIGH); digitalWrite(motorMinus,LOW); delay(500); digitalWrite(motorPlus,LOW); digitalWrite(motorMinus,HIGH); delay(500); } copy and past this code to arduino and upload it channel link : https://www.youtube.com/channel/UCOgVFoF3Vkw3aicoAjDfRng meet u in next blog
