i want to make a small form of this circuit ( both receiver and transmitter circuits ) which can works on 1.5v
or , is there any idea to make it smaller and simpler than that ?
or , is there simillar simple circuits which can dose the same action ?
any information or links or circuits schematics which can help me abt this subject
