How to control a Meccanoid Personnal Robot via Arduino, using 2 Arduino Uno, 1 Arduino Esplora, 4x SRD05VDC relays, 2x BD135 NPN Transistor, 2x HM10 Bluetooth Serial Devices. 2 DC motors are controlled over H-Bridge using 4 Relays and 2 NPN transistors. All servos motors are controlled via LIM, a protocol for linking servo motors. Check the project on my Github to get more informations :
