Here i have used IR in place of buttons. When I do this now, If I hold the one button and press another they both go up, but the state does not change when i released the pressed button. Pressing each button will activate the movement of the related motors and then the wheels. Arduino is a prototype platform (open-source) based on an easy-to-use hardware and software. It is pretty straight forward, but there are some intricacies worth noting. You can also copy and paste the following code into the Arduino IDE. Note that my relay module is 'low level. The clock is connected to her standard bedlamp (which uses a 12 V LED bulb for this purpose. The circuit also includes a buffer between the HC-05's Tx pin and the Arduino's Rx pin. MaxBotix MB1240 Arduino example code - Trigger with push button. Therefore, I make Wall-E wait for two seconds before he does anything. // play the pitch: tone(8, thisPitch, 10);. I also added a button to control the led matrix. In the eighth round, eight LEDs will flash, and the player will have to press eight buttons. That same leg of the button, on its other side, connects through the 10K resistor to the ground to form a complete circuit.
